Shubham Chopra fa7c582e94 [SPARK-15355][CORE] Proactive block replication
## What changes were proposed in this pull request?

We are proposing addition of pro-active block replication in case of executor failures. BlockManagerMasterEndpoint does all the book-keeping to keep a track of all the executors and the blocks they hold. It also keeps a track of which executors are alive through heartbeats. When an executor is removed, all this book-keeping state is updated to reflect the lost executor. This step can be used to identify executors that are still in possession of a copy of the cached data and a message could be sent to them to use the existing "replicate" function to find and place new replicas on other suitable hosts. Blocks replicated this way will let the master know of their existence.

This can happen when an executor is lost, and would that way be pro-active as opposed be being done at query time.
## How was this patch tested?

This patch was tested with existing unit tests along with new unit tests added to test the functionality.

Kay Ousterhout 5cbd3b59ba [SPARK-19560] Improve DAGScheduler tests.
This commit improves the tests that check the case when a
ShuffleMapTask completes successfully on an executor that has
failed.  This commit improves the commenting around the existing
test for this, and adds some additional checks to make it more
clear what went wrong if the tests fail (the fact that these
tests are hard to understand came up in the context of markhamstra's
proposed fix for #16620).

This commit also removes a test that I realized tested exactly
the same functionality.

markhamstra, I verified that the new version of the test still fails (and
in a more helpful way) for your proposed change for #16620.

Currently we can only check the estimated stats in logical plans by debugging. We need to provide an easier and more efficient way for developers/users.

In this pr, we add EXPLAIN COST command to show stats in the optimized logical plan.
E.g.
```
spark-sql> EXPLAIN COST select count(1) from store_returns;

...

jerryshao b0a8c16fec [SPARK-19707][CORE] Improve the invalid path check for sc.addJar
## What changes were proposed in this pull request?

Currently in Spark there're two issues when we add jars with invalid path:

* If the jar path is a empty string {--jar ",dummy.jar"}, then Spark will resolve it to the current directory path and add to classpath / file server, which is unwanted. This is happened in our programatic way to submit Spark application. From my understanding Spark should defensively filter out such empty path.
* If the jar path is a invalid path (file doesn't exist), `addJar` doesn't check it and will still add to file server, the exception will be delayed until job running. Actually this local path could be checked beforehand, no need to wait until task running. We have similar check in `addFile`, but lacks similar similar mechanism in `addJar`.

## How was this patch tested?

Add unit test and local manual verification.

Marcelo Vanzin 17d83e1ee5 [SPARK-19652][UI] Do auth checks for REST API access.
The REST API has a security filter that performs auth checks
based on the UI root's security manager. That works fine when
the UI root is the app's UI, but not when it's the history server.

In the SHS case, all users would be allowed to see all applications
through the REST API, even if the UI itself wouldn't be available
to them.

This change adds auth checks for each app access through the API
too, so that only authorized users can see the app's data.

The change also modifies the existing security filter to use
`HttpServletRequest.getRemoteUser()`, which is used in other
places. That is not necessarily the same as the principal's
name; for example, when using Hadoop's SPNEGO auth filter,
the remote user strips the realm information, which then matches
the user name registered as the owner of the application.

I also renamed the UIRootFromServletContext trait to a more generic
name since I'm using it to store more context information now.

Tested manually with an authentication filter enabled.

[SPARK-19450] Replace askWithRetry with askSync.
## What changes were proposed in this pull request?

`askSync` is already added in `RpcEndpointRef` (see SPARK-19347 and https://github.com/apache/spark/pull/16690#issuecomment-276850068) and `askWithRetry` is marked as deprecated.
As mentioned SPARK-18113(https://github.com/apache/spark/pull/16503#event-927953218):

>askWithRetry is basically an unneeded API, and a leftover from the akka days that doesn't make sense anymore. It's prone to cause deadlocks (exactly because it's blocking), it imposes restrictions on the caller (e.g. idempotency) and other things that people generally don't pay that much attention to when using it.

Since `askWithRetry` is just used inside spark and not in user logic. It might make sense to replace all of them with `askSync`.

## How was this patch tested?
This PR doesn't change code logic, existing unit test can cover.

jinxing 729ce37032 [SPARK-19263] DAGScheduler should avoid sending conflicting task set.
In current `DAGScheduler handleTaskCompletion` code, when event.reason is `Success`, it will first do `stage.pendingPartitions -= task.partitionId`, which maybe a bug when `FetchFailed` happens.

**Think about below**

1.  Stage 0 runs and generates shuffle output data.
2. Stage 1 reads the output from stage 0 and generates more shuffle data. It has two tasks: ShuffleMapTask1 and ShuffleMapTask2, and these tasks are launched on executorA.
3. ShuffleMapTask1 fails to fetch blocks locally and sends a FetchFailed to the driver. The driver marks executorA as lost and updates failedEpoch;
4. The driver resubmits stage 0 so the missing output can be re-generated, and then once it completes, resubmits stage 1 with ShuffleMapTask1x and ShuffleMapTask2x.
5. ShuffleMapTask2 (from the original attempt of stage 1) successfully finishes on executorA and sends Success back to driver. This causes DAGScheduler::handleTaskCompletion to remove partition 2 from stage.pendingPartitions (line 1149), but it does not add the partition to the set of output locations (line 1192), because the task’s epoch is less than the failure epoch for the executor (because of the earlier failure on executor A)
6. ShuffleMapTask1x successfully finishes on executorB, causing the driver to remove partition 1 from stage.pendingPartitions. Combined with the previous step, this means that there are no more pending partitions for the stage, so the DAGScheduler marks the stage as finished (line 1196). However, the shuffle stage is not available (line 1215) because the completion for ShuffleMapTask2 was ignored because of its epoch, so the DAGScheduler resubmits the stage.
7. ShuffleMapTask2x is still running, so when TaskSchedulerImpl::submitTasks is called for the re-submitted stage, it throws an error, because there’s an existing active task set

**In this fix**

If a task completion is from a previous stage attempt and the epoch is too low
(i.e., it was from a failed executor), don't remove the corresponding partition
from pendingPartitions.

Liang-Chi Hsieh 4cc06f4eb1 [SPARK-18986][CORE] ExternalAppendOnlyMap shouldn't fail when forced to spill before calling its iterator
## What changes were proposed in this pull request?

`ExternalAppendOnlyMap.forceSpill` now uses an assert to check if an iterator is not null in the map. However, the assertion is only true after the map is asked for iterator. Before it, if another memory consumer asks more memory than currently available, `ExternalAppendOnlyMap.forceSpill` is also be called too. In this case, we will see failure like this:

    [info]   java.lang.AssertionError: assertion failed
    [info]   at scala.Predef$.assert(Predef.scala:156)
    [info]   at org.apache.spark.util.collection.ExternalAppendOnlyMap.forceSpill(ExternalAppendOnlyMap.scala:196)

José Hiram Soltren 6287c94f08 [SPARK-16554][CORE] Automatically Kill Executors and Nodes when they are Blacklisted
## What changes were proposed in this pull request?

In SPARK-8425, we introduced a mechanism for blacklisting executors and nodes (hosts). After a certain number of failures, these resources would be "blacklisted" and no further work would be assigned to them for some period of time.

In some scenarios, it is better to fail fast, and to simply kill these unreliable resources. This changes proposes to do so by having the BlacklistTracker kill unreliable resources when they would otherwise be "blacklisted".

In order to be thread safe, this code depends on the CoarseGrainedSchedulerBackend sending a message to the driver backend in order to do the actual killing. This also helps to prevent a race which would permit work to begin on a resource (executor or node), between the time the resource is marked for killing and the time at which it is finally killed.

## How was this patch tested?

./dev/run-tests
Ran https://github.com/jsoltren/jose-utils/blob/master/blacklist/test-blacklist.sh, and checked logs to see executors and nodes being killed.

Testing can likely be improved here; suggestions welcome.

Marcelo Vanzin 3fc8e8caf8 [SPARK-17874][CORE] Add SSL port configuration.
Make the SSL port configuration explicit, instead of deriving it
from the non-SSL port, but retain the existing functionality in
case anyone depends on it.

The change starts the HTTPS and HTTP connectors separately, so
that it's possible to use independent ports for each. For that to
work, the initialization of the server needs to be shuffled around
a bit. The change also makes it so the initialization of both
connectors is similar, and end up using the same Scheduler - previously
only the HTTP connector would use the correct one.

Also fixed some outdated documentation about a couple of services
that were removed long ago.

Tested with unit tests and by running spark-shell with SSL configs.

[SPARK-19260] Spaces or "%20" in path parameter are not correctly handled with…
JIRA Issue: https://issues.apache.org/jira/browse/SPARK-19260

## What changes were proposed in this pull request?

1. “spark.history.fs.logDirectory” supports with space character and “%20” characters.
2. As usually, if the run classpath includes hdfs-site.xml and core-site.xml files, the supplied path eg."/test" which does not contain a scheme should be taken as a HDFS path rather than a local path since the path parameter is a Hadoop dir.

## How was this patch tested?

erenavsarogullari 7beb227cc8 [SPARK-17663][CORE] SchedulableBuilder should handle invalid data access via scheduler.allocation.file
## What changes were proposed in this pull request?

If `spark.scheduler.allocation.file` has invalid `minShare` or/and `weight` values, these cause :
- `NumberFormatException` due to `toInt` function
- `SparkContext` can not be initialized.
- It does not show meaningful error message to user.

In a nutshell, this functionality can be more robust by selecting one of the following flows :

**1-** Currently, if `schedulingMode` has an invalid value, a warning message is logged and default value is set as `FIFO`. Same pattern can be used for `minShare`(default: 0) and `weight`(default: 1) as well
**2-** Meaningful error message can be shown to the user for all invalid cases.

PR offers :
- `schedulingMode` handles just empty values. It also needs to be supported for **whitespace**, **non-uppercase**(fair, FaIr etc...) or `SchedulingMode.NONE` cases by setting default value(`FIFO`)
- `minShare` and `weight` handle just empty values. They also need to be supported for **non-integer** cases by setting default values.
- Some refactoring of `PoolSuite`.

**Code to Reproduce :**

```
val conf = new SparkConf().setAppName("spark-fairscheduler").setMaster("local")
conf.set("spark.scheduler.mode", "FAIR")
conf.set("spark.scheduler.allocation.file", "src/main/resources/fairscheduler-invalid-data.xml")
val sc = new SparkContext(conf)
```

**fairscheduler-invalid-data.xml :**

```
<allocations>
    <pool name="production">
        <schedulingMode>FIFO</schedulingMode>
        <weight>invalid_weight</weight>
        <minShare>2</minShare>
    </pool>
</allocations>
```

**Stacktrace :**

Liang-Chi Hsieh 2f523fa0c9 [SPARK-19244][CORE] Sort MemoryConsumers according to their memory usage when spilling
## What changes were proposed in this pull request?

In `TaskMemoryManager `, when we acquire memory by calling `acquireExecutionMemory` and we can't acquire required memory, we will try to spill other memory consumers.

Currently, we simply iterates the memory consumers in a hash set. Normally each time the consumer will be iterated in the same order.

The first issue is that we might spill additional consumers. For example, if consumer 1 uses 10MB, consumer 2 uses 50MB, then consumer 3 acquires 100MB but we can only get 60MB and spilling is needed. We might spill both consumer 1 and consumer 2. But we actually just need to spill consumer 2 and get the required 100MB.

The second issue is that if we spill consumer 1 in first time spilling. After a while, consumer 1 now uses 5MB. Then consumer 4 may acquire some memory and spilling is needed again. Because we iterate the memory consumers in the same order, we will spill consumer 1 again. So for consumer 1, we will produce many small spilling files.

This patch modifies the way iterating the memory consumers. It sorts the memory consumers by their memory usage. So the consumer using more memory will spill first. Once it is spilled, even it acquires few memory again, in next time spilling happens it will not be the consumers to spill again if there are other consumers using more memory than it.

jinxing c86a57f4d1 [SPARK-19437] Rectify spark executor id in HeartbeatReceiverSuite.
## What changes were proposed in this pull request?

The current code in `HeartbeatReceiverSuite`, executorId is set as below:
```
  private val executorId1 = "executor-1"
  private val executorId2 = "executor-2"
```

The executorId is sent to driver when register as below:

```
test("expire dead hosts should kill executors with replacement (SPARK-8119)")  {
  ...
  fakeSchedulerBackend.driverEndpoint.askSync[Boolean](
      RegisterExecutor(executorId1, dummyExecutorEndpointRef1, "1.2.3.4", 0, Map.empty))
  ...
}
```

Receiving `RegisterExecutor` in `CoarseGrainedSchedulerBackend`, the executorId will be compared with `currentExecutorIdCounter` as below:
```
case RegisterExecutor(executorId, executorRef, hostname, cores, logUrls)  =>
  if (executorDataMap.contains(executorId)) {
    executorRef.send(RegisterExecutorFailed("Duplicate executor ID: " + executorId))
    context.reply(true)
  } else {
  ...
  executorDataMap.put(executorId, data)
  if (currentExecutorIdCounter < executorId.toInt) {
    currentExecutorIdCounter = executorId.toInt
  }
  ...
```

`executorId.toInt` will cause NumberformatException.

This unit test can pass currently because of `askWithRetry`, when catching exception, RPC will call again, thus it will go `if` branch and return true.

**To fix**
Rectify executorId and replace `askWithRetry` with `askSync`, refer to https://github.com/apache/spark/pull/16690

Shixiong Zhu 21aa8c32ba [SPARK-19365][CORE] Optimize RequestMessage serialization
## What changes were proposed in this pull request?

Right now Netty PRC serializes `RequestMessage` using Java serialization, and the size of a single message (e.g., RequestMessage(..., "hello")`) is almost 1KB.

This PR optimizes it by serializing `RequestMessage` manually (eliminate unnecessary information from most messages, e.g., class names of `RequestMessage`, `NettyRpcEndpointRef`, ...), and reduces the above message size to 100+ bytes.

## How was this patch tested?

Marcelo Vanzin d3dcb63b97 [SPARK-19220][UI] Make redirection to HTTPS apply to all URIs.
The redirect handler was installed only for the root of the server;
any other context ended up being served directly through the HTTP
port. Since every sub page (e.g. application UIs in the history
server) is a separate servlet context, this meant that everything
but the root was accessible via HTTP still.

The change adds separate names to each connector, and binds contexts
to specific connectors so that content is only served through the
HTTPS connector when it's enabled. In that case, the only thing that
binds to the HTTP connector is the redirect handler.

Tested with new unit tests and by checking a live history server.

Marcelo Vanzin 8f3f73abc1 [SPARK-19139][CORE] New auth mechanism for transport library.
This change introduces a new auth mechanism to the transport library,
to be used when users enable strong encryption. This auth mechanism
has better security than the currently used DIGEST-MD5.

The new protocol uses symmetric key encryption to mutually authenticate
the endpoints, and is very loosely based on ISO/IEC 9798.

The new protocol falls back to SASL when it thinks the remote end is old.
Because SASL does not support asking the server for multiple auth protocols,
which would mean we could re-use the existing SASL code by just adding a
new SASL provider, the protocol is implemented outside of the SASL API
to avoid the boilerplate of adding a new provider.

Details of the auth protocol are discussed in the included README.md
file.

This change partly undos the changes added in SPARK-13331; AES encryption
is now decoupled from SASL authentication. The encryption code itself,
though, has been re-used as part of this change.

Parag Chaudhari 0ff67a1cf9 [SPARK-14049][CORE] Add functionality in spark history sever API to query applications by end time
## What changes were proposed in this pull request?

Currently, spark history server REST API provides functionality to query applications by application start time range based on minDate and maxDate query parameters, but it  lacks support to query applications by their end time. In this pull request we are proposing optional minEndDate and maxEndDate query parameters and filtering capability based on these parameters to spark history server REST API. This functionality can be used for following queries,
1. Applications finished in last 'x' minutes
2. Applications finished before 'y' time
3. Applications finished between 'x' time to 'y' time
4. Applications started from 'x' time and finished before 'y' time.

For backward compatibility, we can keep existing minDate and maxDate query parameters as they are and they can continue support filtering based on start time range.

Existing unit tests and 4 new unit tests.

- adding JSON (de)serialization code for these events;
- augmenting the Executors UI page to show which, and how many, executors are blacklisted;
- adding a unit test to make sure events are being fired;
- adding HistoryServerSuite coverage to verify that the SHS reads these events correctly.
- updates the Executor UI to show Blacklisted/Active/Dead as a tri-state in Executors Status

Updates .rat-excludes to pass tests.

jinxing 33791a8ced [SPARK-18113] Use ask to replace askWithRetry in canCommit and make receiver idempotent.
## What changes were proposed in this pull request?

Method canCommit sends AskPermissionToCommitOutput using askWithRetry. If timeout, it will send again. Thus AskPermissionToCommitOutput can be received multi times. Method canCommit should return the same value when called by the same attempt multi times.

In implementation before this fix, method handleAskPermissionToCommit just check if there is committer already registered, which is not enough. When worker retries AskPermissionToCommitOutput it will get CommitDeniedException, then the task will fail with reason TaskCommitDenied, which is not regarded as a task failure(SPARK-11178), so TaskScheduler will schedule this task infinitely.

In this fix, use `ask` to replace `askWithRetry` in `canCommit` and make receiver idempotent.

Bryan Cutler 3bc2eff888 [SPARK-17568][CORE][DEPLOY] Add spark-submit option to override ivy settings used to resolve packages/artifacts
## What changes were proposed in this pull request?

Adding option in spark-submit to allow overriding the default IvySettings used to resolve artifacts as part of the Spark Packages functionality.  This will allow all artifact resolution to go through a central managed repository, such as Nexus or Artifactory, where site admins can better approve and control what is used with Spark apps.

This change restructures the creation of the IvySettings object in two distinct ways.  First, if the `spark.ivy.settings` option is not defined then `buildIvySettings` will create a default settings instance, as before, with defined repositories (Maven Central) included.  Second, if the option is defined, the ivy settings file will be loaded from the given path and only repositories defined within will be used for artifact resolution.
## How was this patch tested?

Existing tests for default behaviour, Manual tests that load a ivysettings.xml file with local and Nexus repositories defined.  Added new test to load a simple Ivy settings file with a local filesystem resolver.

Kay Ousterhout 2e139eed31 [SPARK-17931] Eliminate unnecessary task (de) serialization
In the existing code, there are three layers of serialization
    involved in sending a task from the scheduler to an executor:
        - A Task object is serialized
        - The Task object is copied to a byte buffer that also
          contains serialized information about any additional JARs,
          files, and Properties needed for the task to execute. This
          byte buffer is stored as the member variable serializedTask
          in the TaskDescription class.
        - The TaskDescription is serialized (in addition to the serialized
          task + JARs, the TaskDescription class contains the task ID and
          other metadata) and sent in a LaunchTask message.

While it *is* necessary to have two layers of serialization, so that
the JAR, file, and Property info can be deserialized prior to
deserializing the Task object, the third layer of deserialization is
unnecessary.  This commit eliminates a layer of serialization by moving
the JARs, files, and Properties into the TaskDescription class.

This commit also serializes the Properties manually (by traversing the map),
as is done with the JARs and files, which reduces the final serialized size.

Unit tests

This is a simpler alternative to the approach proposed in #15505.

shivaram and I did some benchmarking of this and #15505 on a 20-machine m2.4xlarge EC2 machines (160 cores). We ran ~30 trials of code [1] (a very simple job with 10K tasks per stage) and measured the average time per stage:

Before this change: 2490ms
With this change: 2345 ms (so ~6% improvement over the baseline)
With witgo's approach in #15505: 2046 ms (~18% improvement over baseline)

The reason that #15505 has a more significant improvement is that it also moves the serialization from the TaskSchedulerImpl thread to the CoarseGrainedSchedulerBackend thread. I added that functionality on top of this change, and got almost the same improvement [1] as #15505 (average of 2103ms). I think we should decouple these two changes, both so we have some record of the improvement form each individual improvement, and because this change is more about simplifying the code base (the improvement is negligible) while the other is about performance improvement.  The plan, currently, is to merge this PR and then merge the remaining part of #15505 that moves serialization.

[1] The reason the improvement wasn't quite as good as with #15505 when we ran the benchmarks is almost certainly because, at the point when we ran the benchmarks, I hadn't updated the code to manually serialize the Properties (instead the code was using Java's default serialization for the Properties object, whereas #15505 manually serialized the Properties).  This PR has since been updated to manually serialize the Properties, just like the other maps.

jerryshao 4a4c3dc9ca [SPARK-19033][CORE] Add admin acls for history server
## What changes were proposed in this pull request?

Current HistoryServer's ACLs is derived from application event-log, which means the newly changed ACLs cannot be applied to the old data, this will become a problem where newly added admin cannot access the old application history UI, only the new application can be affected.

So here propose to add admin ACLs for history server, any configured user/group could have the view access to all the applications, while the view ACLs derived from application run-time still take effect.

## How was this patch tested?

Unit test added.

Rui Li f5d18af6a8 [SPARK-14958][CORE] Failed task not handled when there's error deserializing failure reason
## What changes were proposed in this pull request?

TaskResultGetter tries to deserialize the TaskEndReason before handling the failed task. If an error is thrown during deserialization, the failed task won't be handled, which leaves the job hanging.
The PR proposes to handle the failed task in a finally block.
## How was this patch tested?

In my case I hit a NoClassDefFoundError and the job hangs. Manually verified the patch can fix it.

Shixiong Zhu 7026ee23e0 [SPARK-17755][CORE] Use workerRef to send RegisterWorkerResponse to avoid the race condition
## What changes were proposed in this pull request?

The root cause of this issue is that RegisterWorkerResponse and LaunchExecutor are sent via two different channels (TCP connections) and their order is not guaranteed.

This PR changes the master and worker codes to use `workerRef` to send RegisterWorkerResponse, so that RegisterWorkerResponse and LaunchExecutor are sent via the same connection. Hence `LaunchExecutor` will always be after `RegisterWorkerResponse` and never be ignored.

jerryshao 31da755c80 [SPARK-18975][CORE] Add an API to remove SparkListener
## What changes were proposed in this pull request?

In current Spark we could add customized SparkListener through `SparkContext#addListener` API, but there's no equivalent API to remove the registered one. In our scenario SparkListener will be added repeatedly accordingly to the changed environment. If lacks the ability to remove listeners, there might be many registered listeners finally, this is unnecessary and potentially affects the performance. So here propose to add an API to remove registered listener.

## How was this patch tested?

Add an unit test to verify it.

And, there are some tests being failed due to the length limitation on cmd in Windows as below:

- `LauncherBackendSuite`:

```
- local: launcher handle *** FAILED *** (30 seconds, 120 milliseconds)
  The code passed to eventually never returned normally. Attempted 283 times over 30.0960053 seconds. Last failure message: The reference was null. (LauncherBackendSuite.scala:56)

```

The executed command is, https://gist.github.com/HyukjinKwon/d3fdd2e694e5c022992838a618a516bd, which is 16K length; however, the length limitation is 8K on Windows. So, it is being failed to launch.

This PR proposes to fix the test failures on Windows and skip the tests failed due to the length limitation

Josh Rosen fa829ce21f [SPARK-18761][CORE] Introduce "task reaper" to oversee task killing in executors
## What changes were proposed in this pull request?

Spark's current task cancellation / task killing mechanism is "best effort" because some tasks may not be interruptible or may not respond to their "killed" flags being set. If a significant fraction of a cluster's task slots are occupied by tasks that have been marked as killed but remain running then this can lead to a situation where new jobs and tasks are starved of resources that are being used by these zombie tasks.

This patch aims to address this problem by adding a "task reaper" mechanism to executors. At a high-level, task killing now launches a new thread which attempts to kill the task and then watches the task and periodically checks whether it has been killed. The TaskReaper will periodically re-attempt to call `TaskRunner.kill()` and will log warnings if the task keeps running. I modified TaskRunner to rename its thread at the start of the task, allowing TaskReaper to take a thread dump and filter it in order to log stacktraces from the exact task thread that we are waiting to finish. If the task has not stopped after a configurable timeout then the TaskReaper will throw an exception to trigger executor JVM death, thereby forcibly freeing any resources consumed by the zombie tasks.

This feature is flagged off by default and is controlled by four new configurations under the `spark.task.reaper.*` namespace. See the updated `configuration.md` doc for details.

## How was this patch tested?

Tested via a new test case in `JobCancellationSuite`, plus manual testing.

Shivaram Venkataraman 4cb49412d1 [SPARK-18836][CORE] Serialize one copy of task metrics in DAGScheduler
## What changes were proposed in this pull request?

Right now we serialize the empty task metrics once per task – Since this is shared across all tasks we could use the same serialized task metrics across all tasks of a stage.

[SPARK-18827][CORE] Fix cannot read broadcast on disk
## What changes were proposed in this pull request?
`NoSuchElementException` will throw since https://github.com/apache/spark/pull/15056 if a broadcast cannot cache in memory. The reason is that that change cannot cover `!unrolled.hasNext` in `next()` function.

This change is to cover the `!unrolled.hasNext` and check `hasNext` before calling `next` in `blockManager.getLocalValues` to make it  more robust.

We can cache and read broadcast even it cannot fit in memory from this pull request.

Imran Rashid 93cdb8a7d0 [SPARK-8425][CORE] Application Level Blacklisting
## What changes were proposed in this pull request?

This builds upon the blacklisting introduced in SPARK-17675 to add blacklisting of executors and nodes for an entire Spark application.  Resources are blacklisted based on tasks that fail, in tasksets that eventually complete successfully; they are automatically returned to the pool of active resources based on a timeout.  Full details are available in a design doc attached to the jira.
## How was this patch tested?

Added unit tests, ran them via Jenkins, also ran a handful of them in a loop to check for flakiness.

The added tests include:
- verifying BlacklistTracker works correctly
- verifying TaskSchedulerImpl interacts with BlacklistTracker correctly (via a mock BlacklistTracker)
- an integration test for the entire scheduler with blacklisting in a few different scenarios

[SPARK-18830][TESTS] Fix tests in PipedRDDSuite to pass on Windows
## What changes were proposed in this pull request?

This PR proposes to fix the tests failed on Windows as below:

```
[info] - pipe with empty partition *** FAILED *** (672 milliseconds)
[info]   Set(0, 4, 5) did not equal Set(0, 5, 6) (PipedRDDSuite.scala:145)
[info]   org.scalatest.exceptions.TestFailedException:
...
```

In this case, `wc -c` counts the characters on both Windows and Linux but the newlines characters on Windows are `\r\n` which are two. So, the counts ends up one more for each.

```
[info] - test pipe exports map_input_file *** FAILED *** (62 milliseconds)
[info]   java.lang.IllegalStateException: Subprocess exited with status 1. Command ran: printenv map_input_file
[info]   at org.apache.spark.rdd.PipedRDD$$anon$1.hasNext(PipedRDD.scala:178)
...
```

```
[info] - test pipe exports mapreduce_map_input_file *** FAILED *** (172 milliseconds)
[info]   java.lang.IllegalStateException: Subprocess exited with status 1. Command ran: printenv mapreduce_map_input_file
[info]   at org.apache.spark.rdd.PipedRDD$$anon$1.hasNext(PipedRDD.scala:178)
...
```

`printenv` command prints the environment variables; however, when environment variables are set to `ProcessBuilder` as lower-cased keys, `printenv` in Windows ignores and does not print this although it is actually set and accessible. (this was tested in [here](https://ci.appveyor.com/project/spark-test/spark/build/208-PipedRDDSuite) for upper-cases with this [diff](https://github.com/apache/spark/compare/master...spark-test:74d39da) and [here](https://ci.appveyor.com/project/spark-test/spark/build/203-PipedRDDSuite) for lower-cases with this [diff](https://github.com/apache/spark/compare/master...spark-test:fde5e37f28032c15a8d8693ba033a8a779a26317). It seems a bug in `printenv`.
(BTW, note that environment variables on Windows are case-insensitive).

This is (I believe) a thirdparty tool on Windows that resembles `printenv` on Linux (installed in AppVeyor environment or Windows Server 2012 R2). This command does not exist, at least, for Windows 7 and 10 (manually tested).

On Windows, we can use `cmd.exe /C set [varname]` officially for this purpose. We could fix the tests with this in order to test if the environment variable is set.

[SPARK-18842][TESTS][LAUNCHER] De-duplicate paths in classpaths in commands for local-cluster mode to work around the path length limitation on Windows
## What changes were proposed in this pull request?

Currently, some tests are being failed and hanging on Windows due to this problem. For the reason in SPARK-18718, some tests using `local-cluster` mode were disabled on Windows due to the length limitation by paths given to classpaths.

The limitation seems roughly 32K (see the [blog in MS](https://blogs.msdn.microsoft.com/oldnewthing/20031210-00/?p=41553/) and [another reference](https://support.thoughtworks.com/hc/en-us/articles/213248526-Getting-around-maximum-command-line-length-is-32767-characters-on-Windows)) but in `local-cluster` mode, executors were being launched as processes with the command such as [here](https://gist.github.com/HyukjinKwon/5bc81061c250d4af5a180869b59d42ea) in (only) tests.

This length is roughly 40K due to the classpaths given to `java` command. However, it seems duplicates are almost half of them. So, if we deduplicate the paths, it seems reduced to roughly 20K with the command, [here](https://gist.github.com/HyukjinKwon/dad0c8db897e5e094684a2dc6a417790).

Maybe, we should consider as some more paths are added in the future but it seems better than disabling all the tests for now with minimised changes.

Therefore, this PR proposes to deduplicate the paths in classpaths in case of launching executors as processes in `local-cluster` mode.

Imran Rashid ac013ea589 [SPARK-18846][SCHEDULER] Fix flakiness in SchedulerIntegrationSuite
There is a small race in SchedulerIntegrationSuite.
The test assumes that the taskscheduler thread
processing that last task will finish before the DAGScheduler processes
the task event and notifies the job waiter, but that is not 100%
guaranteed.

ran the test locally a bunch of times, never failed, though admittedly
it never failed locally for me before either.  However I am nearly 100%
certain this is what caused the failure of one jenkins build

Shixiong Zhu fb3081d3b3 [SPARK-13747][CORE] Fix potential ThreadLocal leaks in RPC when using ForkJoinPool
## What changes were proposed in this pull request?

Some places in SQL may call `RpcEndpointRef.askWithRetry` (e.g., ParquetFileFormat.buildReader -> SparkContext.broadcast -> ... -> BlockManagerMaster.updateBlockInfo -> RpcEndpointRef.askWithRetry), which will finally call `Await.result`. It may cause `java.lang.IllegalArgumentException: spark.sql.execution.id is already set` when running in Scala ForkJoinPool.

This PR includes the following changes to fix this issue:

- Remove `ThreadUtils.awaitResult`
- Rename `ThreadUtils. awaitResultInForkJoinSafely` to `ThreadUtils.awaitResult`
- Replace `Await.result` in RpcTimeout with `ThreadUtils.awaitResult`.

Marcelo Vanzin bc59951bab [SPARK-18773][CORE] Make commons-crypto config translation consistent.
This change moves the logic that translates Spark configuration to
commons-crypto configuration to the network-common module. It also
extends TransportConf and ConfigProvider to provide the necessary
interfaces for the translation to work.

As part of the change, I removed SystemPropertyConfigProvider, which
was mostly used as an "empty config" in unit tests, and adjusted the
very few tests that required a specific config.

I also changed the config keys for AES encryption to live under the
"spark.network." namespace, which is more correct than their previous
names under "spark.authenticate.".

Tested via existing unit test.

Steve Loughran 586d198228 [SPARK-15844][CORE] HistoryServer doesn't come up if spark.authenticate = true
## What changes were proposed in this pull request?

During history server startup, the spark configuration is examined. If security.authentication is
set, log at debug and set the value to false, so that {{SecurityManager}} can be created.

## How was this patch tested?

A new test in `HistoryServerSuite` sets the `spark.authenticate` property to true, tries to create a security manager via a new package-private method `HistoryServer.createSecurityManager(SparkConf)`. This is the method used in `HistoryServer.main`. All other instantiations of a security manager in `HistoryServerSuite` have been switched to the new method, for consistency with the production code.

This PR proposes to fix some tests being failed on Windows as below for several problems.

### Incorrect path handling

### Incorrect separate for JarEntry

After the path fix from above, then `TaskResultGetterSuite` throws another exception as below:

```
[info] - failed task deserialized with the correct classloader (SPARK-11195) *** FAILED *** (907 milliseconds)
[info]   java.lang.ClassNotFoundException: repro.MyException
[info]   at java.net.URLClassLoader.findClass(URLClassLoader.java:381)
...
```

This is because `Paths.get` concatenates the given paths to an OS-specific path (Windows `\` and Linux `/`). However, for `JarEntry` we should comply ZIP specification meaning it should be always `/` according to ZIP specification.

See `4.4.17 file name: (Variable)` in https://pkware.cachefly.net/webdocs/casestudies/APPNOTE.TXT

Davies Liu cf33a86285 [SPARK-4105] retry the fetch or stage if shuffle block is corrupt
## What changes were proposed in this pull request?

There is an outstanding issue that existed for a long time: Sometimes the shuffle blocks are corrupt and can't be decompressed. We recently hit this in three different workloads, sometimes we can reproduce it by every try, sometimes can't. I also found that when the corruption happened, the beginning and end of the blocks are correct, the corruption happen in the middle. There was one case that the string of block id is corrupt by one character. It seems that it's very likely the corruption is introduced by some weird machine/hardware, also the checksum (16 bits) in TCP is not strong enough to identify all the corruption.

Unfortunately, Spark does not have checksum for shuffle blocks or broadcast, the job will fail if any corruption happen in the shuffle block from disk, or broadcast blocks during network. This PR try to detect the corruption after fetching shuffle blocks by decompressing them, because most of the compression already have checksum in them. It will retry the block, or failed with FetchFailure, so the previous stage could be retried on different (still random) machines.

Checksum for broadcast will be added by another PR.

Marcelo Vanzin 93e9d880bf [SPARK-18546][CORE] Fix merging shuffle spills when using encryption.
The problem exists because it's not possible to just concatenate encrypted
partition data from different spill files; currently each partition would
have its own initial vector to set up encryption, and the final merged file
should contain a single initial vector for each merged partiton, otherwise
iterating over each record becomes really hard.

To fix that, UnsafeShuffleWriter now decrypts the partitions when merging,
so that the merged file contains a single initial vector at the start of
the partition data.

Because it's not possible to do that using the fast transferTo path, when
encryption is enabled UnsafeShuffleWriter will revert back to using file
streams when merging. It may be possible to use a hybrid approach when
using encryption, using an intermediate direct buffer when reading from
files and encrypting the data, but that's better left for a separate patch.

As part of the change I made DiskBlockObjectWriter take a SerializerManager
instead of a "wrap stream" closure, since that makes it easier to test the
code without having to mock SerializerManager functionality.

Tested with newly added unit tests (UnsafeShuffleWriterSuite for the write
side and ExternalAppendOnlyMapSuite for integration), and by running some
apps that failed without the fix.

The method `TaskSchedulerImpl.runningTasksByExecutors()` accesses the mutable `executorIdToRunningTaskIds` map without proper synchronization. In addition, as markhamstra pointed out in #15986, the signature's use of parentheses is a little odd given that this is a pure getter method.

Josh Rosen 9a02f68212 [SPARK-18553][CORE] Fix leak of TaskSetManager following executor loss
## What changes were proposed in this pull request?

_This is the master branch version of #15986; the original description follows:_

This patch fixes a critical resource leak in the TaskScheduler which could cause RDDs and ShuffleDependencies to be kept alive indefinitely if an executor with running tasks is permanently lost and the associated stage fails.

This problem was originally identified by analyzing the heap dump of a driver belonging to a cluster that had run out of shuffle space. This dump contained several `ShuffleDependency` instances that were retained by `TaskSetManager`s inside the scheduler but were not otherwise referenced. Each of these `TaskSetManager`s was considered a "zombie" but had no running tasks and therefore should have been cleaned up. However, these zombie task sets were still referenced by the `TaskSchedulerImpl.taskIdToTaskSetManager` map.

Entries are added to the `taskIdToTaskSetManager` map when tasks are launched and are removed inside of `TaskScheduler.statusUpdate()`, which is invoked by the scheduler backend while processing `StatusUpdate` messages from executors. The problem with this design is that a completely dead executor will never send a `StatusUpdate`. There is [some code](072f4c518c/core/src/main/scala/org/apache/spark/scheduler/TaskSchedulerImpl.scala (L338)) in `statusUpdate` which handles tasks that exit with the `TaskState.LOST` state (which is supposed to correspond to a task failure triggered by total executor loss), but this state only seems to be used in Mesos fine-grained mode. There doesn't seem to be any code which performs per-task state cleanup for tasks that were running on an executor that completely disappears without sending any sort of final death message. The `executorLost` and [`removeExecutor`](072f4c518c/core/src/main/scala/org/apache/spark/scheduler/TaskSchedulerImpl.scala (L527)) methods don't appear to perform any cleanup of the `taskId -> *` mappings, causing the leaks observed here.

This patch's fix is to maintain a `executorId -> running task id` mapping so that these `taskId -> *` maps can be properly cleaned up following an executor loss.

There are some potential corner-case interactions that I'm concerned about here, especially some details in [the comment](072f4c518c/core/src/main/scala/org/apache/spark/scheduler/TaskSchedulerImpl.scala (L523)) in `removeExecutor`, so I'd appreciate a very careful review of these changes.

## How was this patch tested?

I added a new unit test to `TaskSchedulerImplSuite`.

Marcelo Vanzin 8b325b17ec [SPARK-18547][CORE] Propagate I/O encryption key when executors register.
This change modifies the method used to propagate encryption keys used during
shuffle. Instead of relying on YARN's UserGroupInformation credential propagation,
this change explicitly distributes the key using the messages exchanged between
driver and executor during registration. When RPC encryption is enabled, this means
key propagation is also secure.

This allows shuffle encryption to work in non-YARN mode, which means that it's
easier to write unit tests for areas of the code that are affected by the feature.

The key is stored in the SecurityManager; because there are many instances of
that class used in the code, the key is only guaranteed to exist in the instance
managed by the SparkEnv. This path was chosen to avoid storing the key in the
SparkConf, which would risk having the key being written to disk as part of the
configuration (as, for example, is done when starting YARN applications).

Tested by new and existing unit tests (which were moved from the YARN module to
core), and by running apps with shuffle encryption enabled.

various logs like YARN and event logs.

This change uses this property to redact information from event logs and YARN
logs. It also, updates the UI code to adhere to this property instead of
hardcoding the logic to decipher which properties are sensitive.

Here's an image of the UI post-redaction:
![image](https://cloud.githubusercontent.com/assets/1709451/20506215/4cc30654-b007-11e6-8aee-4cde253fba2f.png)

Here's the text in the YARN logs, post-redaction:
``HADOOP_CREDSTORE_PASSWORD -> *********(redacted)``

Here's the text in the event logs, post-redaction:
``...,"spark.executorEnv.HADOOP_CREDSTORE_PASSWORD":"*********(redacted)","spark.yarn.appMasterEnv.HADOOP_CREDSTORE_PASSWORD":"*********(redacted)",...``

## How was this patch tested?
1. Unit tests are added to ensure that redaction works.
2. A YARN job reading data off of S3 with confidential information
(hadoop credential provider password) being provided in the environment
variables of driver and executor. And, afterwards, logs were grepped to make
sure that no mention of secret password was present. It was also ensure that
the job was able to read the data off of S3 correctly, thereby ensuring that
the sensitive information was being trickled down to the right places to read
the data.
3. The event logs were checked to make sure no mention of secret password was
present.
4. UI environment tab was checked to make sure there was no secret information
being displayed.

This PR avoids that a result of an expression is negative due to signed integer overflow (e.g. 0x10?????? * 8 < 0). This PR casts each operand to `long` before executing a calculation. Since the result is interpreted as long, the result of the expression is positive.

[SPARK-18422][CORE] Fix wholeTextFiles test to pass on Windows in JavaAPISuite
## What changes were proposed in this pull request?

This PR fixes the test `wholeTextFiles` in `JavaAPISuite.java`. This is failed due to the different path format on Windows.

For example, the path in `container` was

```
C:\projects\spark\target\tmp\1478967560189-0/part-00000
```

whereas `new URI(res._1()).getPath()` was as below:

```
/C:/projects/spark/target/tmp/1478967560189-0/part-00000
```

## How was this patch tested?

Vinayak 06a13ecca7 [SPARK-16808][CORE] History Server main page does not honor APPLICATION_WEB_PROXY_BASE
## What changes were proposed in this pull request?

Application links generated on the history server UI no longer (regression from 1.6) contain the configured spark.ui.proxyBase in the links. To address this, made the uiRoot available globally to all javascripts for Web UI. Updated the mustache template (historypage-template.html) to include the uiroot for rendering links to the applications.

The existing test was not sufficient to verify the scenario where ajax call is used to populate the application listing template, so added a new selenium test case to cover this scenario.

This PR port RDD API to use commit protocol, the changes made here:
1. Add new internal helper class that saves an RDD using a Hadoop OutputFormat named `SparkNewHadoopWriter`, it's similar with `SparkHadoopWriter` but uses commit protocol. This class supports the newer `mapreduce` API, instead of the old `mapred` API which is supported by `SparkHadoopWriter`;
2. Rewrite `PairRDDFunctions.saveAsNewAPIHadoopDataset` function, so it uses commit protocol now.

Josh Rosen 3a710b94b0 [SPARK-18236] Reduce duplicate objects in Spark UI and HistoryServer
## What changes were proposed in this pull request?

When profiling heap dumps from the HistoryServer and live Spark web UIs, I found a large amount of memory being wasted on duplicated objects and strings. This patch's changes remove most of this duplication, resulting in over 40% memory savings for some benchmarks.

- **Task metrics** (6441f0624dfcda9c7193a64bfb416a145b5aabdf): previously, every `TaskUIData` object would have its own instances of `InputMetricsUIData`, `OutputMetricsUIData`, `ShuffleReadMetrics`, and `ShuffleWriteMetrics`, but for many tasks these metrics are irrelevant because they're all zero. This patch changes how we construct these metrics in order to re-use a single immutable "empty" value for the cases where these metrics are empty.
- **TaskInfo.accumulables** (ade86db901127bf13c0e0bdc3f09c933a093bb76): Previously, every `TaskInfo` object had its own empty `ListBuffer` for holding updates from named accumulators. Tasks which didn't use named accumulators still paid for the cost of allocating and storing this empty buffer. To avoid this overhead, I changed the `val` with a mutable buffer into a `var` which holds an immutable Scala list, allowing tasks which do not have named accumulator updates to share the same singleton `Nil` object.
- **String.intern() in JSONProtocol** (7e05630e9a78c455db8c8c499f0590c864624e05): in the HistoryServer, executor hostnames and ids are deserialized from JSON, leading to massive duplication of these string objects. By calling `String.intern()` on the deserialized values we can remove all of this duplication. Since Spark now requires Java 7+ we don't have to worry about string interning exhausting the permgen (see http://java-performance.info/string-intern-in-java-6-7-8/).

## How was this patch tested?

I ran

```
sc.parallelize(1 to 100000, 100000).count()
```

in `spark-shell` with event logging enabled, then loaded that event log in the HistoryServer, performed a full GC, and took a heap dump. According to YourKit, the changes in this patch reduced memory consumption by roughly 28 megabytes (or 770k Java objects):

Here's a table illustrating the drop in objects due to deduplication (the drop is <100k for some objects because some events were dropped from the listener bus; this is a separate, existing bug that I'll address separately after CPU-profiling):

[SPARK-17802] Improved caller context logging.
## What changes were proposed in this pull request?

[SPARK-16757](https://issues.apache.org/jira/browse/SPARK-16757) sets the hadoop `CallerContext` when calling hadoop/hdfs apis to make spark applications more diagnosable in hadoop/hdfs logs. However, the `org.apache.hadoop.ipc.CallerContext` class is only added since [hadoop 2.8](https://issues.apache.org/jira/browse/HDFS-9184), which is not officially releaed yet. So each time `utils.CallerContext.setCurrentContext()` is called (e.g [when a task is created](https://github.com/apache/spark/blob/b678e46/core/src/main/scala/org/apache/spark/scheduler/Task.scala#L95-L96)), a "java.lang.ClassNotFoundException: org.apache.hadoop.ipc.CallerContext"
error is logged, which pollutes the spark logs when there are lots of tasks.

This patch improves this behaviour by only logging the `ClassNotFoundException` once.

Eren Avsarogullari 81d6933e75 [SPARK-17894][CORE] Ensure uniqueness of TaskSetManager name.
`TaskSetManager` should have unique name to avoid adding duplicate ones to parent `Pool` via `SchedulableBuilder`. This problem has been surfaced with following discussion: [[PR: Avoid adding duplicate schedulables]](https://github.com/apache/spark/pull/15326)

**Proposal** :
There is 1x1 relationship between `stageAttemptId` and `TaskSetManager` so `taskSet.Id` covering both `stageId` and `stageAttemptId` looks to be used for uniqueness of `TaskSetManager` name instead of just `stageId`.

**Current TaskSetManager Name** :
`var name = "TaskSet_" + taskSet.stageId.toString`
**Sample**: TaskSet_0

**Proposed TaskSetManager Name** :
`val name = "TaskSet_" + taskSet.Id ` `// taskSet.Id = (stageId + "." + stageAttemptId)`
**Sample** : TaskSet_0.0

Sital Kedia c7ac027d5f [SPARK-17839][CORE] Use Nio's directbuffer instead of BufferedInputStream in order to avoid additional copy from os buffer cache to user buffer
## What changes were proposed in this pull request?

Currently we use BufferedInputStream to read the shuffle file which copies the file content from os buffer cache to the user buffer. This adds additional latency in reading the spill files. We made a change to use java nio's direct buffer to read the spill files and for certain pipelines spilling significant amount of data, we see up to 7% speedup for the entire pipeline.

## How was this patch tested?
Tested by running the job in the cluster and observed up to 7% speedup.

Zhan Zhang ed14633414 [SPARK-17637][SCHEDULER] Packed scheduling for Spark tasks across executors
## What changes were proposed in this pull request?

Restructure the code and implement two new task assigner.
PackedAssigner: try to allocate tasks to the executors with least available cores, so that spark can release reserved executors when dynamic allocation is enabled.

BalancedAssigner: try to allocate tasks to the executors with more available cores in order to balance the workload across all executors.

By default, the original round robin assigner is used.

We test a pipeline, and new PackedAssigner  save around 45% regarding the reserved cpu and memory with dynamic allocation enabled.

Imran Rashid 9ce7d3e542 [SPARK-17675][CORE] Expand Blacklist for TaskSets
## What changes were proposed in this pull request?

This is a step along the way to SPARK-8425.

To enable incremental review, the first step proposed here is to expand the blacklisting within tasksets. In particular, this will enable blacklisting for
* (task, executor) pairs (this already exists via an undocumented config)
* (task, node)
* (taskset, executor)
* (taskset, node)

Adding (task, node) is critical to making spark fault-tolerant of one-bad disk in a cluster, without requiring careful tuning of "spark.task.maxFailures". The other additions are also important to avoid many misleading task failures and long scheduling delays when there is one bad node on a large cluster.

Note that some of the code changes here aren't really required for just this -- they put pieces in place for SPARK-8425 even though they are not used yet (eg. the `BlacklistTracker` helper is a little out of place, `TaskSetBlacklist` holds onto a little more info than it needs to for just this change, and `ExecutorFailuresInTaskSet` is more complex than it needs to be).

## How was this patch tested?

Added unit tests, run tests via jenkins.

[SPARK-17768][CORE] Small (Sum,Count,Mean)Evaluator problems and suboptimalities
## What changes were proposed in this pull request?

Fix:

- GroupedMeanEvaluator and GroupedSumEvaluator are unused, as is the StudentTCacher support class
- CountEvaluator can return a lower bound < 0, when counts can't be negative
- MeanEvaluator will actually fail on exactly 1 datum (yields t-test with 0 DOF)
- CountEvaluator uses a normal distribution, which may be an inappropriate approximation (leading to above)
- Test for SumEvaluator asserts incorrect expected sums – e.g. after observing 10% of data has sum of 2, expectation should be 20, not 38
- CountEvaluator, MeanEvaluator have no unit tests to catch these
- Duplication of distribution code across CountEvaluator, GroupedCountEvaluator
- The stats in each could use a bit of documentation as I had to guess at them
- (Code could use a few cleanups and optimizations too)

Return Iterator of applications internally in history server, for consistency and performance. See https://github.com/apache/spark/pull/15248 for some back-story.

The code called by and calling HistoryServer.getApplicationList wants an Iterator, but this method materializes an Iterable, which potentially causes a performance problem. It's simpler too to make this internal method also pass through an Iterator.

## What changes were proposed in this pull request?

This PR proposes to fix/skip some tests failed on Windows. This PR takes over https://github.com/apache/spark/pull/12696.

**Before**

- **SparkSubmitSuite**

  ```
[info] - launch simple application with spark-submit *** FAILED *** (202 milliseconds)
[info]   java.io.IOException: Cannot run program "./bin/spark-submit" (in directory "C:\projects\spark"): CreateProcess error=2, The system cannot find the file specifie

[info]   java.io.IOException: Cannot run program "./bin/spark-submit" (in directory "C:\projects\spark"): CreateProcess error=2, The system cannot find the file specified
```

- **DiskStoreSuite**

  ```
[info] - reads of memory-mapped and non memory-mapped files are equivalent *** FAILED *** (1 second, 78 milliseconds)
[info]   diskStoreMapped.remove(blockId) was false (DiskStoreSuite.scala:41)
```

**After**

- **SparkSubmitSuite**

  ```
[info] - launch simple application with spark-submit (578 milliseconds)
[info] - includes jars passed in through --jars (1 second, 875 milliseconds)
```

- **DiskStoreSuite**

  ```
[info] DiskStoreSuite:
[info] - reads of memory-mapped and non memory-mapped files are equivalent !!! CANCELED !!! (766 milliseconds
```

For `CreateTableAsSelectSuite` and `FsHistoryProviderSuite`, I could not reproduce as the Java version seems higher than the one that has the bugs about `setReadable(..)` and `setWritable(...)` but as they are bugs reported clearly, it'd be sensible to skip those. We should revert the changes for both back as soon as we drop the support of Java 7.

Eric Liang 4bcd9b728b [SPARK-17740] Spark tests should mock / interpose HDFS to ensure that streams are closed
## What changes were proposed in this pull request?

As a followup to SPARK-17666, ensure filesystem connections are not leaked at least in unit tests. This is done here by intercepting filesystem calls as suggested by JoshRosen . At the end of each test, we assert no filesystem streams are left open.

This applies to all tests using SharedSQLContext or SharedSparkContext.

## How was this patch tested?

I verified that tests in sql and core are indeed using the filesystem backend, and fixed the detected leaks. I also checked that reverting https://github.com/apache/spark/pull/15245 causes many actual test failures due to connection leaks.

Shubham Chopra a26afd5219 [SPARK-15353][CORE] Making peer selection for block replication pluggable
## What changes were proposed in this pull request?

This PR makes block replication strategies pluggable. It provides two trait that can be implemented, one that maps a host to its topology and is used in the master, and the second that helps prioritize a list of peers for block replication and would run in the executors.

This patch contains default implementations of these traits that make sure current Spark behavior is unchanged.

This patch should not change Spark behavior in any way, and was tested with unit tests for storage.

Imran Rashid 3993ebca23 [SPARK-17676][CORE] FsHistoryProvider should ignore hidden files
## What changes were proposed in this pull request?

FsHistoryProvider was writing a hidden file (to check the fs's clock).
Even though it deleted the file immediately, sometimes another thread
would try to scan the files on the fs in-between, and then there would
be an error msg logged which was very misleading for the end-user.
(The logged error was harmless, though.)

## How was this patch tested?

I added one unit test, but to be clear, that test was passing before.  The actual change in behavior in that test is just logging (after the change, there is no more logged error), which I just manually verified.

Imran Rashid 7f779e7439 [SPARK-17648][CORE] TaskScheduler really needs offers to be an IndexedSeq
## What changes were proposed in this pull request?

The Seq[WorkerOffer] is accessed by index, so it really should be an
IndexedSeq, otherwise an O(n) operation becomes O(n^2).  In practice
this hasn't been an issue b/c where these offers are generated, the call
to `.toSeq` just happens to create an IndexedSeq anyway.I got bitten by
this in performance tests I was doing, and its better for the types to be
more precise so eg. a change in Scala doesn't destroy performance.

Weiqing Yang 6a68c5d7b4 [SPARK-16757] Set up Spark caller context to HDFS and YARN
## What changes were proposed in this pull request?

1. Pass `jobId` to Task.
2. Invoke Hadoop APIs.
    * A new function `setCallerContext` is added in `Utils`. `setCallerContext` function invokes APIs of   `org.apache.hadoop.ipc.CallerContext` to set up spark caller contexts, which will be written into `hdfs-audit.log` and Yarn RM audit log.
    * For HDFS: Spark sets up its caller context by invoking`org.apache.hadoop.ipc.CallerContext` in `Task` and Yarn `Client` and `ApplicationMaster`.
    * For Yarn: Spark sets up its caller context by invoking `org.apache.hadoop.ipc.CallerContext` in Yarn `Client`.

## How was this patch tested?
Manual Tests against some Spark applications in Yarn client mode and Yarn cluster mode. Need to check if spark caller contexts are written into HDFS hdfs-audit.log and Yarn RM audit log successfully.

For example, run SparkKmeans in Yarn client mode:
```
./bin/spark-submit --verbose --executor-cores 3 --num-executors 1 --master yarn --deploy-mode client --class org.apache.spark.examples.SparkKMeans examples/target/original-spark-examples_2.11-2.1.0-SNAPSHOT.jar hdfs://localhost:9000/lr_big.txt 2 5
```

**Before**:
There will be no Spark caller context in records of `hdfs-audit.log` and Yarn RM audit log.

**After**:
Spark caller contexts will be written in records of `hdfs-audit.log` and Yarn RM audit log.

These are records in `hdfs-audit.log`:

Burak Yavuz 59d87d2407 [SPARK-17650] malformed url's throw exceptions before bricking Executors
## What changes were proposed in this pull request?

When a malformed URL was sent to Executors through `sc.addJar` and `sc.addFile`, the executors become unusable, because they constantly throw `MalformedURLException`s and can never acknowledge that the file or jar is just bad input.

This PR tries to fix that problem by making sure MalformedURLs can never be submitted through `sc.addJar` and `sc.addFile`. Another solution would be to blacklist bad files and jars on Executors. Maybe fail the first time, and then ignore the second time (but print a warning message).

Imran Rashid 9fcf1c51d5 [SPARK-17623][CORE] Clarify type of TaskEndReason with a failed task.
## What changes were proposed in this pull request?

In TaskResultGetter, enqueueFailedTask currently deserializes the result
as a TaskEndReason. But the type is actually more specific, its a
TaskFailedReason. This just leads to more blind casting later on – it
would be more clear if the msg was cast to the right type immediately,
so method parameter types could be tightened.

## How was this patch tested?

Existing unit tests via jenkins.  Note that the code was already performing a blind-cast to a TaskFailedReason before in any case, just in a different spot, so there shouldn't be any behavior change.

Marcelo Vanzin 2cd1bfa4f0 [SPARK-4563][CORE] Allow driver to advertise a different network address.
The goal of this feature is to allow the Spark driver to run in an
isolated environment, such as a docker container, and be able to use
the host's port forwarding mechanism to be able to accept connections
from the outside world.

The change is restricted to the driver: there is no support for achieving
the same thing on executors (or the YARN AM for that matter). Those still
need full access to the outside world so that, for example, connections
can be made to an executor's block manager.

The core of the change is simple: add a new configuration that tells what's
the address the driver should bind to, which can be different than the address
it advertises to executors (spark.driver.host). Everything else is plumbing
the new configuration where it's needed.

To use the feature, the host starting the container needs to set up the
driver's port range to fall into a range that is being forwarded; this
required the block manager port to need a special configuration just for
the driver, which falls back to the existing spark.blockManager.port when
not set. This way, users can modify the driver settings without affecting
the executors; it would theoretically be nice to also have different
retry counts for driver and executors, but given that docker (at least)
allows forwarding port ranges, we can probably live without that for now.

Because of the nature of the feature it's kinda hard to add unit tests;
I just added a simple one to make sure the configuration works.

This was tested with a docker image running spark-shell with the following
command:

 docker blah blah blah \
   -p 38000-38100:38000-38100 \
   [image] \
   spark-shell \
     --num-executors 3 \
     --conf spark.shuffle.service.enabled=false \
     --conf spark.dynamicAllocation.enabled=false \
     --conf spark.driver.host=[host's address] \
     --conf spark.driver.port=38000 \
     --conf spark.driver.blockManager.port=38020 \
     --conf spark.ui.port=38040

Running on YARN; verified the driver works, executors start up and listen
on ephemeral ports (instead of using the driver's config), and that caching
and shuffling (without the shuffle service) works. Clicked through the UI
to make sure all pages (including executor thread dumps) worked. Also tested
apps without docker, and ran unit tests.

Josh Rosen 8faa5217b4 [SPARK-17491] Close serialization stream to fix wrong answer bug in putIteratorAsBytes()
## What changes were proposed in this pull request?

`MemoryStore.putIteratorAsBytes()` may silently lose values when used with `KryoSerializer` because it does not properly close the serialization stream before attempting to deserialize the already-serialized values, which may cause values buffered in Kryo's internal buffers to not be read.

This is the root cause behind a user-reported "wrong answer" bug in PySpark caching reported by bennoleslie on the Spark user mailing list in a thread titled "pyspark persist MEMORY_ONLY vs MEMORY_AND_DISK". Due to Spark 2.0's automatic use of KryoSerializer for "safe" types (such as byte arrays, primitives, etc.) this misuse of serializers manifested itself as silent data corruption rather than a StreamCorrupted error (which you might get from JavaSerializer).

The minimal fix, implemented here, is to close the serialization stream before attempting to deserialize written values. In addition, this patch adds several additional assertions / precondition checks to prevent misuse of `PartiallySerializedBlock` and `ChunkedByteBufferOutputStream`.

## How was this patch tested?

The original bug was masked by an invalid assert in the memory store test cases: the old assert compared two results record-by-record with `zip` but didn't first check that the lengths of the two collections were equal, causing missing records to go unnoticed. The updated test case reproduced this bug.

In addition, I added a new `PartiallySerializedBlockSuite` to unit test that component.

Josh Rosen 1202075c95 [SPARK-17484] Prevent invalid block locations from being reported after put() exceptions
## What changes were proposed in this pull request?

If a BlockManager `put()` call failed after the BlockManagerMaster was notified of a block's availability then incomplete cleanup logic in a `finally` block would never send a second block status method to inform the master of the block's unavailability. This, in turn, leads to fetch failures and used to be capable of causing complete job failures before #15037 was fixed.

This patch addresses this issue via multiple small changes:

- The `finally` block now calls `removeBlockInternal` when cleaning up from a failed `put()`; in addition to removing the `BlockInfo` entry (which was _all_ that the old cleanup logic did), this code (redundantly) tries to remove the block from the memory and disk stores (as an added layer of defense against bugs lower down in the stack) and optionally notifies the master of block removal (which now happens during exception-triggered cleanup).
- When a BlockManager receives a request for a block that it does not have it will now notify the master to update its block locations. This ensures that bad metadata pointing to non-existent blocks will eventually be fixed. Note that I could have implemented this logic in the block manager client (rather than in the remote server), but that would introduce the problem of distinguishing between transient and permanent failures; on the server, however, we know definitively that the block isn't present.
- Catch `NonFatal` instead of `Exception` to avoid swallowing `InterruptedException`s thrown from synchronous block replication calls.

This patch depends upon the refactorings in #15036, so that other patch will also have to be backported when backporting this fix.

Josh Rosen f9c580f110 [SPARK-17485] Prevent failed remote reads of cached blocks from failing entire job
## What changes were proposed in this pull request?

In Spark's `RDD.getOrCompute` we first try to read a local copy of a cached RDD block, then a remote copy, and only fall back to recomputing the block if no cached copy (local or remote) can be read. This logic works correctly in the case where no remote copies of the block exist, but if there _are_ remote copies and reads of those copies fail (due to network issues or internal Spark bugs) then the BlockManager will throw a `BlockFetchException` that will fail the task (and which could possibly fail the whole job if the read failures keep occurring).

In the cases of TorrentBroadcast and task result fetching we really do want to fail the entire job in case no remote blocks can be fetched, but this logic is inappropriate for reads of cached RDD blocks because those can/should be recomputed in case cached blocks are unavailable.

Therefore, I think that the `BlockManager.getRemoteBytes()` method should never throw on remote fetch errors and, instead, should handle failures by returning `None`.

## How was this patch tested?

Block manager changes should be covered by modified tests in `BlockManagerSuite`: the old tests expected exceptions to be thrown on failed remote reads, while the modified tests now expect `None` to be returned from the `getRemote*` method.

I also manually inspected all usages of `BlockManager.getRemoteValues()`, `getRemoteBytes()`, and `get()` to verify that they correctly pattern-match on the result and handle `None`. Note that these `None` branches are already exercised because the old `getRemoteBytes` returned `None` when no remote locations for the block could be found (which could occur if an executor died and its block manager de-registered with the master).

Spark MemoryStore uses SizeTrackingVector as a temporary unrolling buffer to store all input values that it has read so far before transferring the values to storage memory cache. The problem is that when the input RDD is too big for caching in memory, the temporary unrolling memory SizeTrackingVector is not garbage collected in time. As SizeTrackingVector can occupy all available storage memory, it may cause the executor JVM to run out of memory quickly.

Gurvinder Singh 92ce8d4849 [SPARK-15487][WEB UI] Spark Master UI to reverse proxy Application and Workers UI
## What changes were proposed in this pull request?

This pull request adds the functionality to enable accessing worker and application UI through master UI itself. Thus helps in accessing SparkUI when running spark cluster in closed networks e.g. Kubernetes. Cluster admin needs to expose only spark master UI and rest of the UIs can be in the private network, master UI will reverse proxy the connection request to corresponding resource. It adds the path for workers/application UIs as

WorkerUI: <http/https>://master-publicIP:<port>/target/workerID/
ApplicationUI: <http/https>://master-publicIP:<port>/target/appID/

This makes it easy for users to easily protect the Spark master cluster access by putting some reverse proxy e.g. https://github.com/bitly/oauth2_proxy

## How was this patch tested?

The functionality has been tested manually and there is a unit test too for testing access to worker UI with reverse proxy address.

Eric Liang 649fa4bf1d [SPARK-17370] Shuffle service files not invalidated when a slave is lost
## What changes were proposed in this pull request?

DAGScheduler invalidates shuffle files when an executor loss event occurs, but not when the external shuffle service is enabled. This is because when shuffle service is on, the shuffle file lifetime can exceed the executor lifetime.

However, it also doesn't invalidate shuffle files when the shuffle service itself is lost (due to whole slave loss). This can cause long hangs when slaves are lost since the file loss is not detected until a subsequent stage attempts to read the shuffle files.

The proposed fix is to also invalidate shuffle files when an executor is lost due to a `SlaveLost` event.

## How was this patch tested?

Unit tests, also verified on an actual cluster that slave loss invalidates shuffle files immediately as expected.

Josh Rosen 29cfab3f15 [SPARK-17110] Fix StreamCorruptionException in BlockManager.getRemoteValues()
## What changes were proposed in this pull request?

This patch fixes a `java.io.StreamCorruptedException` error affecting remote reads of cached values when certain data types are used. The problem stems from #11801 / SPARK-13990, a patch to have Spark automatically pick the "best" serializer when caching RDDs. If PySpark cached a PythonRDD, then this would be cached as an `RDD[Array[Byte]]` and the automatic serializer selection would pick KryoSerializer for replication and block transfer. However, the `getRemoteValues()` / `getRemoteBytes()` code path did not pass proper class tags in order to enable the same serializer to be used during deserialization, causing Java to be inappropriately used instead of Kryo, leading to the StreamCorruptedException.

We already fixed a similar bug in #14311, which dealt with similar issues in block replication. Prior to that patch, it seems that we had no tests to ensure that block replication actually succeeded. Similarly, prior to this bug fix patch it looks like we had no tests to perform remote reads of cached data, which is why this bug was able to remain latent for so long.

This patch addresses the bug by modifying `BlockManager`'s `get()` and  `getRemoteValues()` methods to accept ClassTags, allowing the proper class tag to be threaded in the `getOrElseUpdate` code path (which is used by `rdd.iterator`)

## How was this patch tested?

Extended the caching tests in `DistributedSuite` to exercise the `getRemoteValues` path, plus manual testing to verify that the PySpark bug reproduction in SPARK-17110 is fixed.

Angus Gerry a0aac4b775 [SPARK-16533][CORE] resolve deadlocking in driver when executors die
## What changes were proposed in this pull request?
This pull request reverts the changes made as a part of #14605, which simply side-steps the deadlock issue. Instead, I propose the following approach:
* Use `scheduleWithFixedDelay` when calling `ExecutorAllocationManager.schedule` for scheduling executor requests. The intent of this is that if invocations are delayed beyond the default schedule interval on account of lock contention, then we avoid a situation where calls to `schedule` are made back-to-back, potentially releasing and then immediately reacquiring these locks - further exacerbating contention.
* Replace a number of calls to `askWithRetry` with `ask` inside of message handling code in `CoarseGrainedSchedulerBackend` and its ilk. This allows us queue messages with the relevant endpoints, release whatever locks we might be holding, and then block whilst awaiting the response. This change is made at the cost of being able to retry should sending the message fail, as retrying outside of the lock could easily cause race conditions if other conflicting messages have been sent whilst awaiting a response. I believe this to be the lesser of two evils, as in many cases these RPC calls are to process local components, and so failures are more likely to be deterministic, and timeouts are more likely to be caused by lock contention.

## How was this patch tested?
Existing tests, and manual tests under yarn-client mode.

serialization works with both java and kryo (and hopefully any other
custom serializer).

Added unit test to make sure SparkConf remains serializable and the
reader works with both built-in serializers.

Alex Bozarth 891ac2b914 [SPARK-15083][WEB UI] History Server can OOM due to unlimited TaskUIData
## What changes were proposed in this pull request?

Based on #12990 by tankkyo

Since the History Server currently loads all application's data it can OOM if too many applications have a significant task count. `spark.ui.trimTasks` (default: false) can be set to true to trim tasks by `spark.ui.retainedTasks` (default: 10000)

(This is a "quick fix" to help those running into the problem until a update of how the history server loads app data can be done)

## How was this patch tested?

Manual testing and dev/run-tests

Eric Liang 8e223ea67a [SPARK-16550][SPARK-17042][CORE] Certain classes fail to deserialize in block manager replication
## What changes were proposed in this pull request?

This is a straightforward clone of JoshRosen 's original patch. I have follow-up changes to fix block replication for repl-defined classes as well, but those appear to be flaking tests so I'm going to leave that for SPARK-17042

## How was this patch tested?

End-to-end test in ReplSuite (also more tests in DistributedSuite from the original patch).

Nick Lavers 5377fc6236 [SPARK-16961][CORE] Fixed off-by-one error that biased randomizeInPlace
JIRA issue link:
https://issues.apache.org/jira/browse/SPARK-16961

Changed one line of Utils.randomizeInPlace to allow elements to stay in place.

Created a unit test that runs a Pearson's chi squared test to determine whether the output diverges significantly from a uniform distribution.

Marcelo Vanzin 5da6c4b24f [SPARK-16671][CORE][SQL] Consolidate code to do variable substitution.
Both core and sql have slightly different code that does variable substitution
of config values. This change refactors that code and encapsulates the logic
of reading config values and expading variables in a new helper class, which
can be configured so that both core and sql can use it without losing existing
functionality, and allows for easier testing and makes it easier to add more
features in the future.

Tested with existing and new unit tests, and by running spark-shell with
some configs referencing variables and making sure it behaved as expected.
