These listeners weren't really meant for external consumption, but they're
public and marked with DeveloperApi. Adding the deprecated tag warns people
that they may soon go away (as they will as part of the work for SPARK-18085).
Note that not all types made public by https://github.com/apache/spark/pull/648
are being deprecated. Some remaining types are still exposed through the
SparkListener API.
Also note the text for StorageStatus is a tiny bit different, since I'm not
so sure I'll be able to remove it. But the effect for the users should be the
same (they should stop trying to use it).

Closes#17766 from vanzin/SPARK-20421.
This change does a more thorough redaction of sensitive information from logs and UI
Add unit tests that ensure that no regressions happen that leak sensitive information to the logs.
The motivation for this change was appearance of password like so in `SparkListenerEnvironmentUpdate` in event logs under some JVM configurations:
`"sun.java.command":"org.apache.spark.deploy.SparkSubmit ... --conf spark.executorEnv.HADOOP_CREDSTORE_PASSWORD=secret_password ..."
`
Previously redaction logic was only checking if the key matched the secret regex pattern, it'd redact it's value. That worked for most cases. However, in the above case, the key (sun.java.command) doesn't tell much, so the value needs to be searched. This PR expands the check to check for values as well.
## How was this patch tested?
New unit tests added that ensure that no sensitive information is present in the event logs or the yarn logs. Old unit test in UtilsSuite was modified because the test was asserting that a non-sensitive property's value won't be redacted. However, the non-sensitive value had the literal "secret" in it which was causing it to redact. Simply updating the non-sensitive property's value to another arbitrary value (that didn't have "secret" in it) fixed it.

## What changes were proposed in this pull request?
Current SHS (Spark History Server) two different ACLs:
* ACL of base URL, it is controlled by "spark.acls.enabled" or "spark.ui.acls.enabled", and with this enabled, only user configured with "spark.admin.acls" (or group) or "spark.ui.view.acls" (or group), or the user who started SHS could list all the applications, otherwise none of them can be listed. This will also affect REST APIs which listing the summary of all apps and one app.
* Per application ACL. This is controlled by "spark.history.ui.acls.enabled". With this enabled only history admin user and user/group who ran this app can access the details of this app.
With this two ACLs, we may encounter several unexpected behaviors:
1. if base URL's ACL (`spark.acls.enable`) is enabled but user A has no view permission. User "A" cannot see the app list but could still access details of it's own app.
2. if ACLs of base URL (`spark.acls.enable`) is disabled, then user "A" could download any application's event log, even it is not run by user "A".
3. The changes of Live UI's ACL will affect History UI's ACL which share the same conf file.
The unexpected behaviors is mainly because we have two different ACLs, ideally we should have only one to manage all.
So to improve SHS's ACL mechanism, here in this PR proposed to:
1. Disable "spark.acls.enable" and only use "spark.history.ui.acls.enable" for history server.
2. Check permission for event-log download REST API.
With this PR:
1. Admin user could see/download the list of all applications, as well as application details.
2. Normal user could see the list of all applications, but can only download and check the details of applications accessible to him.
## How was this patch tested?
New UTs are added, also verified in real cluster.

'Submitted Time' field, the date format **has been formatted**, in running Applications table or Completed Applicationstable in master web ui, **it is correct.**
e.g.
Running Applications
Application ID Name Cores Memory per Executor **Submitted Time** User State Duration

**Format after the time easier to observe, and consistent with the applications table,so I think it's worth fixing.**

## What changes were proposed in this pull request?
In the current Spark's HistoryServer we expected to get `AccessControlException` during listing all the files, but unfortunately it was not worked because we actually doesn't check the access permission and no other calls will throw such exception. What was worse is that this check will be deferred until reading files, which is not necessary and quite verbose, since it will be printed out the exception in every 10 seconds when checking the files.
So here with this fix, we actually check the read permission during listing the files, which could avoid unnecessary file read later on and suppress the verbose log.

This PR proposes to run Spark unidoc to test Javadoc 8 build as Javadoc 8 is easily re-breakable.
There are several problems with it:
- It introduces little extra bit of time to run the tests. In my case, it took 1.5 mins more (`Elapsed :[94.8746569157]`). How it was tested is described in "How was this patch tested?".
- > One problem that I noticed was that Unidoc appeared to be processing test sources: if we can find a way to exclude those from being processed in the first place then that might significantly speed things up.
(see joshrosen's [comment](https://issues.apache.org/jira/browse/SPARK-18692?focusedCommentId=15947627&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-15947627))
To complete this automated build, It also suggests to fix existing Javadoc breaks / ones introduced by test codes as described above.
There fixes are similar instances that previously fixed. Please refer https://github.com/apache/spark/pull/15999 and https://github.com/apache/spark/pull/16013

With [SPARK-13992](https://issues.apache.org/jira/browse/SPARK-13992), Spark supports persisting data into off-heap memory, but the usage of on-heap and off-heap memory is not exposed currently, it is not so convenient for user to monitor and profile, so here propose to expose off-heap memory as well as on-heap memory usage in various places:
1. Spark UI's executor page will display both on-heap and off-heap memory usage.
2. REST request returns both on-heap and off-heap memory.
3. Also this can be gotten from MetricsSystem.
4. Last this usage can be obtained programmatically from SparkListener.
Attach the UI changes:
Backward compatibility is also considered for event-log and REST API. Old event log can still be replayed with off-heap usage displayed as 0. For REST API, only adds the new fields, so JSON backward compatibility can still be kept.

## What changes were proposed in this pull request?
If tasks throw non-interrupted exceptions on kill (e.g. java.nio.channels.ClosedByInterruptException), their death is reported back as TaskFailed instead of TaskKilled. This causes stage failure in some cases.
This is reproducible as follows. Run the following, and then use SparkContext.killTaskAttempt to kill one of the tasks. The entire stage will fail since we threw a RuntimeException instead of InterruptedException.
```
spark.range(100).repartition(100).foreach { i =>
try {
Thread.sleep(10000000)
} catch {
case t: InterruptedException =>
throw new RuntimeException(t)
}
}
```
Based on the code in TaskSetManager, I think this also affects kills of speculative tasks. However, since the number of speculated tasks is few, and usually you need to fail a task a few times before the stage is cancelled, it unlikely this would be noticed in production unless both speculation was enabled and the num allowed task failures was = 1.
We should probably unconditionally return TaskKilled instead of TaskFailed if the task was killed by the driver, regardless of the actual exception thrown.

## What changes were proposed in this pull request?
Implementations of strategies for resilient block replication for different resource managers that replicate the 3-replica strategy used by HDFS, where the first replica is on an executor, the second replica within the same rack as the executor and a third replica on a different rack.
The implementation involves providing two pluggable classes, one running in the driver that provides topology information for every host at cluster start and the second prioritizing a list of peer BlockManagerIds.
The prioritization itself can be thought of an optimization problem to find a minimal set of peers that satisfy certain objectives and replicating to these peers first. The objectives can be used to express richer constraints over and above HDFS like 3-replica strategy.

The internal FileCommitProtocol interface returns all task commit messages in bulk to the implementation when a job finishes. However, it is sometimes useful to access those messages before the job completes, so that the driver gets incremental progress updates before the job finishes.
This adds an `onTaskCommit` listener to the internal api.

Closes#17388 from jerryshao/SPARK-20059.
This change modifies the way block data is encrypted to make the more
common cases faster, while penalizing an edge case. As a side effect
of the change, all data that goes through the block manager is now
encrypted only when needed, including the previous path (broadcast
variables) where that did not happen.
The way the change works is by not encrypting data that is stored in
memory; so if a serialized block is in memory, it will only be encrypted
once it is evicted to disk.
The penalty comes when transferring that encrypted data from disk. If the
data ends up in memory again, it is as efficient as before; but if the
evicted block needs to be transferred directly to a remote executor, then
there's now a performance penalty, since the code now uses a custom
FileRegion implementation to decrypt the data before transferring.
This also means that block data transferred between executors now is
not encrypted (and thus relies on the network library encryption support
for secrecy). Shuffle blocks are still transferred in encrypted form,
since they're handled in a slightly different way by the code. This also
keeps compatibility with existing external shuffle services, which transfer
encrypted shuffle blocks, and avoids having to make the external service
aware of encryption at all.
The serialization and deserialization APIs in the SerializerManager now
do not do encryption automatically; callers need to explicitly wrap their
streams with an appropriate crypto stream before using those.
As a result of these changes, some of the workarounds added in SPARK-19520
are removed here.
Testing: a new trait ("EncryptionFunSuite") was added that provides an easy
way to run a test twice, with encryption on and off; broadcast, block manager
and caching tests were modified to use this new trait so that the existing
tests exercise both encrypted and non-encrypted paths. I also ran some
applications with encryption turned on to verify that they still work,
including streaming tests that failed without the fix for SPARK-19520.

We must set the taskset to zombie before the DAGScheduler handles the taskEnded event. It's possible the taskEnded event will cause the DAGScheduler to launch a new stage attempt (this happens when map output data was lost), and if this happens before the taskSet has been set to zombie, it will appear that we have conflicting task sets.

## What changes were proposed in this pull request?
Executors cache a list of their peers that is refreshed by default every minute. The cached stale references were randomly being used for replication. Since those executors were removed from the master, they did not occur in the block locations as reported by the master. This was fixed by
1. Refreshing peer cache in the block manager before trying to pro-actively replicate. This way the probability of replicating to a failed executor is eliminated.
2. Explicitly stopping the block manager in the tests. This shuts down the RPC endpoint use by the block manager. This way, even if a block manager tries to replicate using a stale reference, the replication logic should take care of refreshing the list of peers after failure.

This commit adds a killTaskAttempt method to SparkContext, to allow users to
kill tasks so that they can be re-scheduled elsewhere.
This also refactors the task kill path to allow specifying a reason for the task kill. The reason is propagated opaquely through events, and will show up in the UI automatically as `(N killed: $reason)` and `TaskKilled: $reason`. Without this change, there is no way to provide the user feedback through the UI.
Currently used reasons are "stage cancelled", "another attempt succeeded", and "killed via SparkContext.killTask". The user can also specify a custom reason through `SparkContext.killTask`.

The previously hardcoded max 4 retries per stage is not suitable for all cluster configurations. Since spark retries a stage at the sign of the first fetch failure, you can easily end up with many stage retries to discover all the failures. In particular, two scenarios this value should change are (1) if there are more than 4 executors per node; in that case, it may take 4 retries to discover the problem with each executor on the node and (2) during cluster maintenance on large clusters, where multiple machines are serviced at once, but you also cannot afford total cluster downtime. By making this value configurable, cluster managers can tune this value to something more appropriate to their cluster configuration.

The following FIFO & FAIR Schedulers Pool usage cases need to have unit test coverage :
- FIFO Scheduler just uses **root pool** so even if `spark.scheduler.pool` property is set, related pool is not created and `TaskSetManagers` are added to **root pool**.
- FAIR Scheduler uses `default pool` when `spark.scheduler.pool` property is not set. This can be happened when
- `Properties` object is **null**,
- `Properties` object is **empty**(`new Properties()`),
- **default pool** is set(`spark.scheduler.pool=default`).
- FAIR Scheduler creates a **new pool** with **default values** when `spark.scheduler.pool` property points a **non-existent** pool. This can be happened when **scheduler allocation file** is not set or it does not contain related pool.

## What changes were proposed in this pull request?
It is sometimes useful to use multiple threads in a task to parallelize tasks. These threads might register some completion/failure listeners to clean up when the task completes or fails. We currently cannot register such a callback and be sure that it will get called, because the context might be in the process of invoking its callbacks, when the the callback gets registered.
This PR improves this by making sure that you cannot add a completion/failure listener from a different thread when the context is being marked as completed/failed in another thread. This is done by synchronizing these methods on the task context itself.
Failure listeners were called only once. Completion listeners now follow the same pattern; this lifts the idempotency requirement for completion listeners and makes it easier to implement them. In some cases we can (accidentally) add a completion/failure listener after the fact, these listeners will be called immediately in order make sure we can safely clean-up after a task.
As a result of this change we could make the `failure` and `completed` flags non-volatile. The `isCompleted()` method now uses synchronization to ensure that updates are visible across threads.

Fault-tolerance in spark requires special handling of shuffle fetch
failures. The Executor would catch FetchFailedException and send a
special msg back to the driver.
However, intervening user code could intercept that exception, and wrap
it with something else. This even happens in SparkSQL. So rather than
checking the thrown exception only, we'll store the fetch failure directly
in the TaskContext, where users can't touch it.

## What changes were proposed in this pull request?
Previously it was possible for there to be a race between a task failure and committing the output of a task. For example, the driver may mark a task attempt as failed due to an executor heartbeat timeout (possibly due to GC), but the task attempt actually ends up coordinating with the OutputCommitCoordinator once the executor recovers and committing its result. This will lead to any retry attempt failing because the task result has already been committed despite the original attempt failing.
This ensures that any previously failed task attempts cannot enter the commit protocol.

## What changes were proposed in this pull request?
This change redacts senstive information (based on `spark.redaction.regex` property)
from the Spark Submit console logs. Such sensitive information is already being
redacted from event logs and yarn logs, etc.
## How was this patch tested?
Testing was done manually to make sure that the console logs were not printing any
sensitive information.
Here's some output from the console:
```
Spark properties used, including those specified through
--conf and those from the properties file /etc/spark2/conf/spark-defaults.conf:
(spark.yarn.appMasterEnv.HADOOP_CREDSTORE_PASSWORD,*********(redacted))
(spark.authenticate,false)
(spark.executorEnv.HADOOP_CREDSTORE_PASSWORD,*********(redacted))
```
```
System properties:
(spark.yarn.appMasterEnv.HADOOP_CREDSTORE_PASSWORD,*********(redacted))
(spark.authenticate,false)
(spark.executorEnv.HADOOP_CREDSTORE_PASSWORD,*********(redacted))
```
There is a risk if new print statements were added to the console down the road, sensitive information may still get leaked, since there is no test that asserts on the console log output. I considered it out of the scope of this JIRA to write an integration test to make sure new leaks don't happen in the future.
Running unit tests to make sure nothing else is broken by this change.

## What changes were proposed in this pull request?
When function 'executorLost' is invoked in class 'TaskSetManager', it's significant to judge whether variable 'isZombie' is set to true.
This pull request fixes the following hang:
1.Open speculation switch in the application.
2.Run this app and suppose last task of shuffleMapStage 1 finishes. Let's get the record straight, from the eyes of DAG, this stage really finishes, and from the eyes of TaskSetManager, variable 'isZombie' is set to true, but variable runningTasksSet isn't empty because of speculation.
3.Suddenly, executor 3 is lost. TaskScheduler receiving this signal, invokes all executorLost functions of rootPool's taskSetManagers. DAG receiving this signal, removes all this executor's outputLocs.
4.TaskSetManager adds all this executor's tasks to pendingTasks and tells DAG they will be resubmitted (Attention: possibly not on time).
5.DAG starts to submit a new waitingStage, let's say shuffleMapStage 2, and going to find that shuffleMapStage 1 is its missing parent because some outputLocs are removed due to executor lost. Then DAG submits shuffleMapStage 1 again.
6.DAG still receives Task 'Resubmitted' signal from old taskSetManager, and increases the number of pendingTasks of shuffleMapStage 1 each time. However, old taskSetManager won't resolve new task to submit because its variable 'isZombie' is set to true.
7.Finally shuffleMapStage 1 never finishes in DAG together with all stages depending on it.

currently if multiple streaming queries listeners exists, when a QueryTerminatedEvent is triggered, only one of the listeners will be invoked while the rest of the listeners will ignore the event.
this is caused since the the streaming queries listeners bus holds a set of running queries ids and when a termination event is triggered, after the first listeners is handling the event, the terminated query id is being removed from the set.
in this PR, the query id will be removed from the set only after all the listeners handles the event

## 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.

Adds a test case that ensures that Executors gracefully handle a task that fails to deserialize, by sending back a reasonable failure message. This does not change any behavior (the prior behavior was already correct), it just adds a test case to prevent regression.

Closes#16930 from squito/executor_task_deserialization.
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 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`.

Author: uncleGen <hustyugm@gmail.com>
Closes#16949 from uncleGen/SPARK-16122.
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.

To ease debugging, most of Spark SQL internals have public level visibility. Two of the most important internal states, sharedState and sessionState, however, are package private. It would make more sense to open these up as well with clear documentation that they are internal.
In addition, users currently have way to set active/default SparkSession, but no way to actually get them back. We should open those up as well.

`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`.

Closes#16790 from jinxing64/SPARK-19450.
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.

`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

Radix sort require that half of array as free (as temporary space), so we use 0.5 as the scale factor to make sure that BytesToBytesMap will not have more items than 1/2 of capacity. Turned out this is not true, the current implementation of append() could leave 1 more item than the threshold (1/2 of capacity) in the array, which break the requirement of radix sort (fail the assert in 2.2, or fail to insert into InMemorySorter in 2.1).

If a new option `wholeFile` is set to `true` the JSON reader will parse each file (instead of a single line) as a value. This is done with Jackson streaming and it should be capable of parsing very large documents, assuming the row will fit in memory.
Because the file is not buffered in memory the corrupt record handling is also slightly different when `wholeFile` is enabled: the corrupt column will contain the filename instead of the literal JSON if there is a parsing failure. It would be easy to extend this to add the parser location (line, column and byte offsets) to the output if desired.
These changes have allowed types other than `String` to be parsed. Support for `UTF8String` and `Text` have been added (alongside `String` and `InputFormat`) and no longer require a conversion to `String` just for parsing.
I've also included a few other changes that generate slightly better bytecode and (imo) make it more obvious when and where boxing is occurring in the parser. These are included as separate commits, let me know if they should be flattened into this PR or moved to a new one.

Spark's I/O encryption uses an ephemeral key for each driver instance.
So driver B cannot decrypt data written by driver A since it doesn't
have the correct key.
The write ahead log is used for recovery, thus needs to be readable by
a different driver. So it cannot be encrypted by Spark's I/O encryption
code.
The BlockManager APIs used by the WAL code to write the data automatically
encrypt data, so changes are needed so that callers can to opt out of
encryption.
Aside from that, the "putBytes" API in the BlockManager does not do
encryption, so a separate situation arised where the WAL would write
unencrypted data to the BM and, when those blocks were read, decryption
would fail. So the WAL code needs to ask the BM to encrypt that data
when encryption is enabled; this code is not optimal since it results
in a (temporary) second copy of the data block in memory, but should be
OK for now until a more performant solution is added. The non-encryption
case should not be affected.

Netty's `MessageToMessageEncoder` uses [Javassist](91a0bdc17a/common/src/main/java/io/netty/util/internal/JavassistTypeParameterMatcherGenerator.java (L62)) to generate a matcher class and the implementation calls `Class.forName` to check if this class is already generated. If `MessageEncoder` or `MessageDecoder` is created in `ExecutorClassLoader.findClass`, it will cause `ClassCircularityError`. This is because loading this Netty generated class will call `ExecutorClassLoader.findClass` to search this class, and `ExecutorClassLoader` will try to use RPC to load it and cause to load the non-exist matcher class again. JVM will report `ClassCircularityError` to prevent such infinite recursion.
##### Why it only happens in Maven builds
It's because Maven and SBT have different class loader tree. The Maven build will set a URLClassLoader as the current context class loader to run the tests and expose this issue. The class loader tree is as following:
```
bootstrap class loader ------ ... ----- REPL class loader ---- ExecutorClassLoader
|
|
URLClasssLoader
```
The SBT build uses the bootstrap class loader directly and `ReplSuite.test("propagation of local properties")` is the first test in ReplSuite, which happens to load `io/netty/util/internal/__matchers__/org/apache/spark/network/protocol/MessageMatcher` into the bootstrap class loader (Note: in maven build, it's loaded into URLClasssLoader so it cannot be found in ExecutorClassLoader). This issue can be reproduced in SBT as well. Here are the produce steps:
- Enable `hadoop.caller.context.enabled`.
- Replace `Class.forName` with `Utils.classForName` in `object CallerContext`.
- Ignore `ReplSuite.test("propagation of local properties")`.
- Run `ReplSuite` using SBT.
This PR just creates a singleton MessageEncoder and MessageDecoder and makes sure they are created before switching to ExecutorClassLoader. TransportContext will be created when creating RpcEnv and that happens before creating ExecutorClassLoader.

The pendingPartitions instance variable should be moved to ShuffleMapStage,
because it is only used by ShuffleMapStages. This change is purely refactoring
and does not change functionality.
I fixed this in an attempt to clarify some of the discussion around #16620, which I was having trouble reasoning about. I stole the helpful comment Imran wrote for pendingPartitions and used it here.

Fair Scheduler Logging for the following cases can be useful for the user.
1. If **valid** `spark.scheduler.allocation.file` property is set, user can be informed and aware which scheduler file is processed when `SparkContext` initializes.
2. If **invalid** `spark.scheduler.allocation.file` property is set, currently, the following stacktrace is shown to user. In addition to this, more meaningful message can be shown to user by emphasizing the problem at building level of fair scheduler. Also other potential issues can be covered at this level as **Fair Scheduler can not be built. + exception stacktrace**
```

```
3. If `spark.scheduler.allocation.file` property is not set and **default** fair scheduler file (**fairscheduler.xml**) is found in classpath, it will be loaded but currently, user is not informed for using default file so logging can be useful as **Fair Scheduler file: fairscheduler.xml is found successfully and will be parsed.**
4. If **spark.scheduler.allocation.file** property is not set and **default** fair scheduler file does not exist in classpath, currently, user is not informed so logging can be useful as **No Fair Scheduler file found.**
Also this PR is related with https://github.com/apache/spark/pull/15237 to emphasize fileName in warning logs when fair scheduler file has invalid minShare, weight or schedulingMode values.

## 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.

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.

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>

## 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.

## 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

Closes#16773 from zsxwing/connect-timeout.
## What changes were proposed in this pull request?
`ReceiverSupervisorImpl` on executor side reports block's meta back to `ReceiverTracker` on driver side. In current code, `askWithRetry` is used. However, for `AddBlock`, `ReceiverTracker` is not idempotent, which may result in messages are processed multiple times.
**To reproduce**:
1. Check if it is the first time receiving `AddBlock` in `ReceiverTracker`, if so sleep long enough(say 200 seconds), thus the first RPC call will be timeout in `askWithRetry`, then `AddBlock` will be resent.
2. Rebuild Spark and run following job:
```
def streamProcessing(): Unit = {
val conf = new SparkConf()
.setAppName("StreamingTest")
.setMaster(masterUrl)
val ssc = new StreamingContext(conf, Seconds(200))
val stream = ssc.socketTextStream("localhost", 1234)
stream.print()
ssc.start()
ssc.awaitTermination()
}
```
**To fix**:
It makes sense to provide a blocking version `ask` in RpcEndpointRef, as mentioned in SPARK-18113 (https://github.com/apache/spark/pull/16503#event-927953218). Because Netty RPC layer will not drop messages. `askWithRetry` is a leftover from akka days. 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.

Closes#16698 from maropu/SparkFilesDoc.
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.

So when checkpoint() is called on them, its the partitionRDD that actually gets checkpointed. However since isCheckpointed() also overridden to call partitionRDD.isCheckpointed, EdgeRDD/VertexRDD.isCheckpointed returns true even though this RDD is actually not checkpointed.
This would have been fine except the RDD's internal logic for computing the RDD depends on isCheckpointed(). So for VertexRDD/EdgeRDD, since isCheckpointed is true, when computing Spark tries to read checkpoint data of VertexRDD/EdgeRDD even though they are not actually checkpointed. Through a crazy sequence of call forwarding, it reads checkpoint data of partitionsRDD and tries to cast it to types in Vertex/EdgeRDD. This leads to ClassCastException.
The minimal fix that does not change any public behavior is to modify RDD internal to not use public override-able API for internal logic.

Closes#15396 from tdas/SPARK-14804.
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.

## 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.

For unevaluated `\n`, evaluate it and enable line break, for Streaming WebUI `stages` page and `job` page.
(I didn't change Scala source file, since Jetty server has to somehow indicate line break and js to code display it.)
(This PR is a continue from previous PR https://github.com/apache/spark/pull/15353 for the same issue, sorry being so long time)
Two changes:
1. RDD Node tooltipText is actually showing the `<circle>` `title` property, so I set extra attribute in `spark-dag-viz.js`: `.attr("data-html", "true")`
`<circle x="-5" y="-5" r="5" data-toggle="tooltip" data-placement="bottom" title="" data-original-title="ParallelCollectionRDD [9]\nmakeRDD at QueueStream.scala:49"></circle>`
2. Static `<tspan>` text of each stage, split by `/n`, and append an extra `<tspan>` element to its parentNode
`<text><tspan xml:space="preserve" dy="1em" x="1">reduceByKey</tspan><tspan xml:space="preserve" dy="1em" x="1">reduceByKey/n 23:34:49</tspan></text>

Although Spark history server UI shows task ‘status’ and ‘duration’ fields, it does not expose these fields in the REST API response. For the Spark history server API users, it is not possible to determine task status and duration. Spark history server has access to task status and duration from event log, but it is not exposing these in API. This patch is proposed to expose task ‘status’ and ‘duration’ fields in Spark history server REST API.

Builds on top of work in SPARK-8425 to update Application Level Blacklisting in the scheduler.
## What changes were proposed in this pull request?
Adds a UI to these patches by:
- defining new listener events for blacklisting and unblacklisting, nodes and executors;
- sending said events at the relevant points in BlacklistTracker;
- 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.

## 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.

## What changes were proposed in this pull request?
For some datasources which are based on HadoopRDD or NewHadoopRDD, such as spark-xml, InputFileBlockHolder doesn't work with Python UDF.
The method to reproduce it is, running the following codes with `bin/pyspark --packages com.databricks:spark-xml_2.11:0.4.1`:
from pyspark.sql.functions import udf,input_file_name
from pyspark.sql.types import StringType
from pyspark.sql import SparkSession
def filename(path):
return path
session = SparkSession.builder.appName('APP').getOrCreate()
session.udf.register('sameText', filename)
sameText = udf(filename, StringType())
df = session.read.format('xml').load('a.xml', rowTag='root').select('*', input_file_name().alias('file'))
df.select('file').show() # works
df.select(sameText(df['file'])).show() # returns empty content
The issue is because in `HadoopRDD` and `NewHadoopRDD` we set the file block's info in `InputFileBlockHolder` before the returned iterator begins consuming. `InputFileBlockHolder` will record this info into thread local variable. When running Python UDF in batch, we set up another thread to consume the iterator from child plan's output rdd, so we can't read the info back in another thread.
To fix this, we have to set the info in `InputFileBlockHolder` after the iterator begins consuming. So the info can be read in correct thread.
## How was this patch tested?
Manual test with above example codes for spark-xml package on pyspark: `bin/pyspark --packages com.databricks:spark-xml_2.11:0.4.1`.

## What changes were proposed in this pull request?
Inserting data into Hive tables has its own implementation that is distinct from data sources: `InsertIntoHiveTable`, `SparkHiveWriterContainer` and `SparkHiveDynamicPartitionWriterContainer`.
Note that one other major difference is that data source tables write directly to the final destination without using some staging directory, and then Spark itself adds the partitions/tables to the catalog. Hive tables actually write to some staging directory, and then call Hive metastore's loadPartition/loadTable function to load those data in. So we still need to keep `InsertIntoHiveTable` to put this special logic. In the future, we should think of writing to the hive table location directly, so that we don't need to call `loadTable`/`loadPartition` at the end and remove `InsertIntoHiveTable`.
This PR removes `SparkHiveWriterContainer` and `SparkHiveDynamicPartitionWriterContainer`, and create a `HiveFileFormat` to implement the write logic. In the future, we should also implement the read logic in `HiveFileFormat`.

## What changes were proposed in this pull request?
We have a config `spark.sql.files.ignoreCorruptFiles` which can be used to ignore corrupt files when reading files in SQL. Currently the `ignoreCorruptFiles` config has two issues and can't work for Parquet:
1. We only ignore corrupt files in `FileScanRDD` . Actually, we begin to read those files as early as inferring data schema from the files. For corrupt files, we can't read the schema and fail the program. A related issue reported at http://apache-spark-developers-list.1001551.n3.nabble.com/Skip-Corrupted-Parquet-blocks-footer-tc20418.html
2. In `FileScanRDD`, we assume that we only begin to read the files when starting to consume the iterator. However, it is possibly the files are read before that. In this case, `ignoreCorruptFiles` config doesn't work too.
This patch targets Parquet datasource. If this direction is ok, we can address the same issue for other datasources like Orc.
Two main changes in this patch:
1. Replace `ParquetFileReader.readAllFootersInParallel` by implementing the logic to read footers in multi-threaded manner
We can't ignore corrupt files if we use `ParquetFileReader.readAllFootersInParallel`. So this patch implements the logic to do the similar thing in `readParquetFootersInParallel`.
2. In `FileScanRDD`, we need to ignore corrupt file too when we call `readFunction` to return iterator.
One thing to notice is:
We read schema from Parquet file's footer. The method to read footer `ParquetFileReader.readFooter` throws `RuntimeException`, instead of `IOException`, if it can't successfully read the footer. Please check out df9d8e4154/parquet-hadoop/src/main/java/org/apache/parquet/hadoop/ParquetFileReader.java (L470). So this patch catches `RuntimeException`. One concern is that it might also shadow other runtime exceptions other than reading corrupt files.

Currently in SQL we implement overwrites by calling fs.delete() directly on the original data. This is not ideal since we the original files end up deleted even if the job aborts. We should extend the commit protocol to allow file overwrites to be managed as well.

Existing tests. I also fixed a bunch of tests that were depending on the commit protocol implementation being set to the legacy mapreduce one.

## 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.

JIRA Issue: https://issues.apache.org/jira/browse/SPARK-19026
SPARK_LOCAL_DIRS (Standalone) can be a comma-separated list of multiple directories on different disks, e.g. SPARK_LOCAL_DIRS=/dir1,/dir2,/dir3, if there is a IOExecption when create sub directory on dir3 , the sub directory which have been created successfully on dir1 and dir2 cannot be deleted anymore when the application finishes.
So we should catch the IOExecption at Utils.createDirectory , otherwise the variable "appDirectories(appId)" which the function maybeCleanupApplication calls will not be set then dir1 and dir2 will not be cleaned up .

Closes#16439 from zuotingbing/master.
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.

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.

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.

## What changes were proposed in this pull request?
This issue was reported by wangyum.
In the AllJobsPage, JobPage and StagePage, the description length was limited before like as follows.
But recently, the limitation seems to have been accidentally removed.
The cause is that some tables are no longer `sortable` class although they were, and `sortable` class does not only mark tables as sortable but also limited the width of their child `td` elements.
The reason why now some tables are not `sortable` class is because another sortable mechanism was introduced by #13620 and #13708 with pagination feature.
To fix this issue, I've introduced new class `table-cell-width-limited` which limits the description cell width and the description is like what it was.

Right now the name of threads created by Netty for Spark RPC are `shuffle-client-**` and `shuffle-server-**`. It's pretty confusing.

- TransportChannelHandler.channelActive and channelInactive should call the corresponding super methods.
- Make ShuffleBlockFetcherIterator throw NoSuchElementException if it has no more elements. Otherwise, if the caller calls `next` without `hasNext`, it will just hang.

## 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.

## 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.
Author: Josh Rosen <joshrosen@databricks.com>
Closes#16189 from JoshRosen/cancellation.
## What changes were proposed in this pull request?
In order to respond to task cancellation, Spark tasks must periodically check `TaskContext.isInterrupted()`, but this check is missing on a few critical read paths used in Spark SQL, including `FileScanRDD`, `JDBCRDD`, and UnsafeSorter-based sorts. This can cause interrupted / cancelled tasks to continue running and become zombies (as also described in #16189).
This patch aims to fix this problem by adding `TaskContext.isInterrupted()` checks to these paths. Note that I could have used `InterruptibleIterator` to simply wrap a bunch of iterators but in some cases this would have an adverse performance penalty or might not be effective due to certain special uses of Iterators in Spark SQL. Instead, I inlined `InterruptibleIterator`-style logic into existing iterator subclasses.
## How was this patch tested?
Tested manually in `spark-shell` with two different reproductions of non-cancellable tasks, one involving scans of huge files and another involving sort-merge joins that spill to disk. Both causes of zombie tasks are fixed by the changes added here.

`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.

After SPARK-12588 Remove HTTPBroadcast [1], the one and only implementation of BroadcastFactory is TorrentBroadcastFactory and the spark.broadcast.factory conf has removed.
however the scaladoc says [2]:
/**
* An interface for all the broadcast implementations in Spark (to allow
* multiple broadcast implementations). SparkContext uses a user-specified
* BroadcastFactory implementation to instantiate a particular broadcast for the
* entire Spark job.
*/
so we should modify the comment that SparkContext will not use a user-specified BroadcastFactory implementation

## 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

`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.

Closes#16254 from HyukjinKwon/pipe-errors.
## 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.

Closes#16266 from HyukjinKwon/disable-local-cluster-tests.
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

When I added a visibility check for the logs column on the executors page in #14382 the method I used only ran the check on the initial DataTable creation and not subsequent page loads. I moved the check out of the table definition and instead it runs on each page load. The jQuery DataTable functionality used is the same.

## 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`.

Closes#16145 from jaceklaskowski/rdd-overrides-removed.
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.

## 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.

### Incorrect separate for JarEntry
After the path fix from above, then `TaskResultGetterSuite` throws another exception as below:
```

[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

## 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.

* This PR changes `JVMObjectTracker` from `object` to `class` and let its instance associated with each RBackend. So we can manage the lifecycle of JVM objects when there are multiple `RBackend` sessions. `RBackend.close` will clear the object tracker explicitly.
* I assume that `SQLUtils` and `RRunner` do not need to track JVM instances, which could be wrong.
* Small refactor of `SerDe.sqlSerDe` to increase readability.
## How was this patch tested?
* Added unit tests for `JVMObjectTracker`.
* Wait for Jenkins to run full tests.

## What changes were proposed in this pull request?
When `SparkContext.stop` is called in `Utils.tryOrStopSparkContext` (the following three places), it will cause deadlock because the `stop` method needs to wait for the thread running `stop` to exit.
- ContextCleaner.keepCleaning
- LiveListenerBus.listenerThread.run
- TaskSchedulerImpl.start
This PR adds `SparkContext.stopInNewThread` and uses it to eliminate the potential deadlock. I also removed my changes in #15775 since they are not necessary now.

- Removed the`attempt.completed ` filter so cleaner would include the orphan inprogress files.
- Use loading time for inprogress files as lastUpdated. Keep using the modTime for completed files. First one will prevent deletion of inprogress job files. Second one will ensure that lastUpdated time won't change for completed jobs in an event of HistoryServer reboot.

When SSL is enabled, the Spark shell shows:
```
Spark context Web UI available at https://192.168.99.1:4040
```
This is wrong because 4040 is http, not https. It redirects to the https port.
More importantly, this introduces several broken links in the UI. For example, in the master UI, the worker link is https:8081 instead of http:8081 or https:8481.

## What changes were proposed in this pull request?
BytesToBytesMap currently does not release the in-memory storage (the longArray variable) after it spills to disk. This is typically not a problem during aggregation because the longArray should be much smaller than the pages, and because we grow the longArray at a conservative rate.
However this can lead to an OOM when an already running task is allocated more than its fair share, this can happen because of a scheduling delay. In this case the longArray can grow beyond the fair share of memory for the task. This becomes problematic when the task spills and the long array is not freed, that causes subsequent memory allocation requests to be denied by the memory manager resulting in an OOM.
This PR fixes this issuing by freeing the longArray when the BytesToBytesMap spills.

## What changes were proposed in this pull request?
It seems some APIs such as `PairRDDFunctions.saveAsHadoopDataset()` do not close the record writer before issuing the commit for the task.
On Windows, the output in the temp directory is being open and output committer tries to rename it from temp directory to the output directory after finishing writing.
So, it fails to move the file. It seems we should close the writer actually before committing the task like the other writers such as `FileFormatWriter`.
Identified failure was as below:
```

## What changes were proposed in this pull request?
We currently have function input_file_name to get the path of the input file, but don't have functions to get the block start offset and length. This patch introduces two functions:
1. input_file_block_start: returns the file block start offset, or -1 if not available.
2. input_file_block_length: returns the file block length, or -1 if not available.
## How was this patch tested?
Updated existing test cases in ColumnExpressionSuite that covered input_file_name to also cover the two new functions.

## What changes were proposed in this pull request?
In Spark 2.1 ListingFileCatalog was significantly refactored (and renamed to InMemoryFileIndex). This introduced a regression where parallelism could only be introduced at the very top of the tree. However, in many cases (e.g. `spark.read.parquet(topLevelDir)`), the top of the tree is only a single directory.
This PR simplifies and fixes the parallel recursive listing code to allow parallelism to be introduced at any level during recursive descent (though note that once we decide to list a sub-tree in parallel, the sub-tree is listed in serial on executors).
