## What changes were proposed in this pull request?
This patch applies redaction to command line arguments before logging them. This applies to two resource managers: standalone cluster and YARN.
This patch only concerns about arguments starting with `-D` since Spark is likely passing the Spark configuration to command line arguments as `-Dspark.blabla=blabla`. More change is necessary if we also want to handle the case of `--conf spark.blabla=blabla`.
## How was this patch tested?
Added UT for redact logic. This patch only touches how to log so not easy to add UT regarding it.

Since the yarn module is actually private to Spark, this interface was never
actually "public". Since it has no use inside of Spark, let's avoid adding
a yarn-specific extension that isn't public, and point any potential users
are more general solutions (like using a SparkListener).

Before this PR the method `BlockManager#putBlockDataAsStream()` (which is used during block replication where the block data is received as a stream) was reading the whole block content into the memory even at DISK_ONLY storage level.
With this change the received block data (which was temporary stored in a file) is just simply moved into the right location backing the target block. This way a possible OOM error is avoided.
In this implementation to save code duplications the method `doPutBytes` is refactored into a template method called `BlockStoreUpdater` which has a separate implementation to handle byte buffer based and temporary file based block store updates.
With existing unit tests of `DistributedSuite` (the ones dealing with replications):
- caching on disk, replicated (encryption = off) (with replication as stream)
- caching on disk, replicated (encryption = on) (with replication as stream)
- caching in memory, serialized, replicated (encryption = on) (with replication as stream)
- caching in memory, serialized, replicated (encryption = off) (with replication as stream)
- etc.
And with new unit tests testing `putBlockDataAsStream` method directly:
- test putBlockDataAsStream with caching (encryption = off)
- test putBlockDataAsStream with caching (encryption = on)
- test putBlockDataAsStream with caching on disk (encryption = off)
- test putBlockDataAsStream with caching on disk (encryption = on)

## What changes were proposed in this pull request?
`prepareSubmitEnvironment` performs globbing that will fail in the case where a proxy user (`--proxy-user`) doesn't have permission to the file. This is a bug also with 2.3, so we should backport, as currently you can't launch an application that for instance is passing a file under `--archives`, and that file is owned by the target user.
The solution is to call `prepareSubmitEnvironment` within a doAs context if proxying.
## How was this patch tested?
Manual tests running with `--proxy-user` and `--archives`, before and after, showing that the globbing is successful when the resource is owned by the target user.
I've looked at writing unit tests, but I am not sure I can do that cleanly (perhaps with a custom FileSystem). Open to ideas.

## What changes were proposed in this pull request?
This PR targets to support Arrow optimization for conversion from Spark DataFrame to R DataFrame.
Like PySpark side, it falls back to non-optimization code path when it's unable to use Arrow optimization.
This can be tested as below:
```bash
$ ./bin/sparkR --conf spark.sql.execution.arrow.enabled=true
```
```r
collect(createDataFrame(mtcars))
```
### Requirements
- R 3.5.x
- Arrow package 0.12+
```bash
Rscript -e 'remotes::install_github("apache/arrowapache-arrow-0.12.0", subdir = "r")'
```
**Note:** currently, Arrow R package is not in CRAN. Please take a look at ARROW-3204.
**Note:** currently, Arrow R package seems not supporting Windows. Please take a look at ARROW-3204.
### Benchmarks
**Shall**
```bash
sync && sudo purge
./bin/sparkR --conf spark.sql.execution.arrow.enabled=false --driver-memory 4g
```
```bash
sync && sudo purge
./bin/sparkR --conf spark.sql.execution.arrow.enabled=true --driver-memory 4g
```
**R code**
```r
df <- cache(createDataFrame(read.csv("500000.csv")))
count(df)
test <- function() {
options(digits.secs = 6) # milliseconds
start.time <- Sys.time()
collect(df)
end.time <- Sys.time()
time.taken <- end.time - start.time
print(time.taken)
}
test()
```
**Data (350 MB):**
```r
object.size(read.csv("500000.csv"))
350379504 bytes
```
"500000 Records" http://eforexcel.com/wp/downloads-16-sample-csv-files-data-sets-for-testing/
**Results**
```
Time difference of 221.32014 secs
```
```
Time difference of 15.51145 secs
```
The performance improvement was around **1426%**.
### Limitations:
- For now, Arrow optimization with R does not support when the data is `raw`, and when user explicitly gives float type in the schema. They produce corrupt values. In this case, we decide to fall back to non-optimization code path.
- Due to ARROW-4512, it cannot send and receive batch by batch. It has to send all batches in Arrow stream format at once. It needs improvement later.
## How was this patch tested?
Existing tests related with Arrow optimization cover this change. Also, manually tested.

`HadoopDelegationTokenProvider` has basically the same functionality just like `ServiceCredentialProvider` so the interfaces can be merged.
`YARNHadoopDelegationTokenManager` now loads `ServiceCredentialProvider`s in one step. The drawback of this if one provider fails all others are not loaded. `HadoopDelegationTokenManager` loads `HadoopDelegationTokenProvider`s independently so it provides more robust behaviour.

* Deleted `YARNHadoopDelegationTokenManager` and `ServiceCredentialProvider`

This patch proposes to change the approach on extracting log urls as well as attributes from YARN executor:

- TO-BE: let YARN executor self-extracting information
This approach leads us to populate more attributes like nodemanager's IPC port which can let us configure custom log url to JHS log url directly.

## What changes were proposed in this pull request?
In the PR, I propose to use `System.nanoTime()` instead of `System.currentTimeMillis()` in measurements of time intervals.
`System.currentTimeMillis()` returns current wallclock time and will follow changes to the system clock. Thus, negative wallclock adjustments can cause timeouts to "hang" for a long time (until wallclock time has caught up to its previous value again). This can happen when ntpd does a "step" after the network has been disconnected for some time. The most canonical example is during system bootup when DHCP takes longer than usual. This can lead to failures that are really hard to understand/reproduce. `System.nanoTime()` is guaranteed to be monotonically increasing irrespective of wallclock changes.

Recently, when I was reading some code of `BlockManager.getBlockData`, I found that there are useless code that would never reach. The related codes is as below:
```
override def getBlockData(blockId: BlockId): ManagedBuffer = {
if (blockId.isShuffle) {
shuffleManager.shuffleBlockResolver.getBlockData(blockId.asInstanceOf[ShuffleBlockId])
} else {
getLocalBytes(blockId) match {
case Some(blockData) =>
new BlockManagerManagedBuffer(blockInfoManager, blockId, blockData, true)
case None =>
// If this block manager receives a request for a block that it doesn't have then it's
// likely that the master has outdated block statuses for this block. Therefore, we send
// an RPC so that this block is marked as being unavailable from this block manager.
reportBlockStatus(blockId, BlockStatus.empty)
throw new BlockNotFoundException(blockId.toString)
}
}
}
```
```
def getLocalBytes(blockId: BlockId): Option[BlockData] = {
logDebug(s"Getting local block $blockId as bytes")
// As an optimization for map output fetches, if the block is for a shuffle, return it
// without acquiring a lock; the disk store never deletes (recent) items so this should work
if (blockId.isShuffle) {
val shuffleBlockResolver = shuffleManager.shuffleBlockResolver
// TODO: This should gracefully handle case where local block is not available. Currently
// downstream code will throw an exception.
val buf = new ChunkedByteBuffer(
shuffleBlockResolver.getBlockData(blockId.asInstanceOf[ShuffleBlockId]).nioByteBuffer())
Some(new ByteBufferBlockData(buf, true))
} else {
blockInfoManager.lockForReading(blockId).map { info => doGetLocalBytes(blockId, info) }
}
}
```
the `blockId.isShuffle` is checked twice, but however it seems that in the method calling hierarchy of `BlockManager.getLocalBytes`, the another callsite of the `BlockManager.getLocalBytes` is at `TorrentBroadcast.readBlocks` where the blockId can never be a `ShuffleBlockId`.
So I think we should remove these useless code for easy reading.

## What changes were proposed in this pull request?
Currently, spark would not release ShuffleBlockFetcherIterator until the whole task finished.In some conditions, it incurs memory leak.
An example is `rdd.repartition(m).coalesce(n, shuffle = false).save`, each `ShuffleBlockFetcherIterator` contains some metas about mapStatus(`blocksByAddress`) and each resultTask will keep n(max to shuffle partitions) shuffleBlockFetcherIterator and the memory would never released until the task completion, for they are referenced by the completion callbacks of TaskContext. In some case, it may take huge memory and incurs OOM.
Actually, We can release ShuffleBlockFetcherIterator as soon as it's consumed.
This PR is to resolve this problem.

This patch proposes adding a new configuration on SHS: custom executor log URL pattern. This will enable end users to replace executor logs to other than RM provide, like external log service, which enables to serve executor logs when NodeManager becomes unavailable in case of YARN.
End users can build their own of custom executor log URLs with pre-defined patterns which would be vary on each resource manager. This patch adds some patterns to YARN resource manager. (For others, there's even no executor log url available so cannot define patterns as well.)
Please refer the doc change as well as added UTs in this patch to see how to set up the feature.

This fix replaces the Threshold with a Filter for ConsoleAppender which checks
to ensure that either the logLevel is greater than thresholdLevel (shell log
level) or the log originated from a custom defined logger. In these cases, it
lets a log event go through, otherwise it doesn't.
1. Ensured that custom log level works when set by default (via log4j.properties)
2. Ensured that logs are not printed twice when log level is changed by setLogLevel
3. Ensured that custom logs are printed when log level is changed back by setLogLevel

This change addes a new mode for credential renewal that does not require
a keytab; it uses the local ticket cache instead, so it works while the
user keeps the cache valid.
This can be useful for, e.g., people running long spark-shell sessions where
their kerberos login is kept up-to-date.
The main change to enable this behavior is in HadoopDelegationTokenManager,
with a small change in the HDFS token provider. The other changes are to avoid
creating duplicate tokens when submitting the application to YARN; they allow
the tokens from the scheduler to be sent to the YARN AM, reducing the round trips
to HDFS.
For that, the scheduler initialization code was changed a little bit so that
the tokens are available when the YARN client is initialized. That basically
takes care of a long-standing TODO that was in the code to clean up configuration
propagation to the driver's RPC endpoint (in CoarseGrainedSchedulerBackend).
Tested with an app designed to stress this functionality, with both keytab and
cache-based logins. Some basic kerberos tests on k8s also.

## What changes were proposed in this pull request?
While obtaining token from hbase service , spark uses deprecated API of hbase ,
```public static Token<AuthenticationTokenIdentifier> obtainToken(Configuration conf)```
This deprecated API is already been removed from hbase 2.x version as part of the hbase 2.x major release. https://issues.apache.org/jira/browse/HBASE-14713_
there is one more stable API in
```public static Token<AuthenticationTokenIdentifier> obtainToken(Connection conn)``` in TokenUtil class
spark shall use this stable api for getting the delegation token.
To invoke this api first connection object has to be retrieved from ConnectionFactory and the same connection can be passed to obtainToken(Connection conn) for getting token.
eg: Call ```public static Connection createConnection(Configuration conf)```
, then call ```public static Token<AuthenticationTokenIdentifier> obtainToken( Connection conn)```.
## How was this patch tested?
Manual testing is been done.
Manual test result:
Before fix:
After fix:
1. Create 2 tables in hbase shell
>Launch hbase shell
>Enter commands to create tables and load data
create 'table1','cf'
put 'table1','row1','cf:cid','20'
create 'table2','cf'
put 'table2','row1','cf:cid','30'
>Show values command
get 'table1','row1','cf:cid' will diplay value as 20
get 'table2','row1','cf:cid' will diplay value as 30
2.Run SparkHbasetoHbase class in testSpark.jar using spark-submit
spark-submit --master yarn-cluster --class com.mrs.example.spark.SparkHbasetoHbase --conf "spark.yarn.security.credentials.hbase.enabled"="true" --conf "spark.security.credentials.hbase.enabled"="true" --keytab /opt/client/user.keytab --principal sen testSpark.jar
The SparkHbasetoHbase test class will update the value of table2 with sum of values of table1 & table2.
table2 = table1+table2
As we can see in the snapshot the spark job has been successfully able to interact with hbase service and able to update the row count.

This is a followup of #16989
The fetch-big-block-to-disk feature is disabled by default, because it's not compatible with external shuffle service prior to Spark 2.2. The client sends stream request to fetch block chunks, and old shuffle service can't support it.
After 2 years, Spark 2.2 has EOL, and now it's safe to turn on this feature by default

SPARK-21568 made a change to ensure that progress bar is enabled for spark-shell
by default but not for other apps. Before that change, this was distinguished
using log-level which is not a good way to determine the same as users can change
the default log-level. That commit changed the way to determine whether current
app is running in spark-shell or not but it left the log-level part as it is,
which causes this regression. SPARK-25118 changed the default log level to INFO
for spark-shell because of which the progress bar is not enabled anymore.
This commit will remove the log-level check for enabling progress bar for
spark-shell as it is not necessary and seems to be a leftover from SPARK-21568

Now in `TransportRequestHandler.processStreamRequest`, when a stream request is processed, the stream id is not registered with the current channel in stream manager. It should do that so in case of that the channel gets terminated we can remove associated streams of stream requests too.
This also cleans up channel registration in `StreamManager`. Since `StreamManager` doesn't register channel but only `OneForOneStreamManager` does it, this removes `registerChannel` from `StreamManager`. When `OneForOneStreamManager` goes to register stream, it will also register channel for the stream.

Introducing shared polled ByteBuf allocators.
This feature can be enabled via the "spark.network.sharedByteBufAllocators.enabled" configuration.
When it is on then only two pooled ByteBuf allocators are created:
- one for transport servers where caching is allowed and
- one for transport clients where caching is disabled
This way the cache allowance remains as before.
Both shareable pools are created with numCores parameter set to 0 (which defaults to the available processors) as conf.serverThreads() and conf.clientThreads() are module dependant and the lazy creation of this allocators would lead to unpredicted behaviour.
When "spark.network.sharedByteBufAllocators.enabled" is false then a new allocator is created for every transport client and server separately as was before this PR.

Currently there is code scattered in a bunch of places to do different
things related to HTTP security, such as access control, setting
security-related headers, and filtering out bad content. This makes it
really easy to miss these things when writing new UI code.
This change creates a new filter that does all of those things, and
makes sure that all servlet handlers that are attached to the UI get
the new filter and any user-defined filters consistently. The extent
of the actual features should be the same as before.
The new filter is added at the end of the filter chain, because authentication
is done by custom filters and thus needs to happen first. This means that
custom filters see unfiltered HTTP requests - which is actually the current
behavior anyway.
As a side-effect of some of the code refactoring, handlers added after
the initial set also get wrapped with a GzipHandler, which didn't happen
before.
Tested with added unit tests and in a history server with SPNEGO auth
configured.

This change modifies the behavior of the delegation token code when running
on YARN, so that the driver controls the renewal, in both client and cluster
mode. For that, a few different things were changed:
* The AM code only runs code that needs DTs when DTs are available.
In a way, this restores the AM behavior to what it was pre-SPARK-23361, but
keeping the fix added in that bug. Basically, all the AM code is run in a
"UGI.doAs()" block; but code that needs to talk to HDFS (basically the
distributed cache handling code) was delayed to the point where the driver
is up and running, and thus when valid delegation tokens are available.
* SparkSubmit / ApplicationMaster now handle user login, not the token manager.
The previous AM code was relying on the token manager to keep the user
logged in when keytabs are used. This required some odd APIs in the token
manager and the AM so that the right UGI was exposed and used in the right
places.
After this change, the logged in user is handled separately from the token
manager, so the API was cleaned up, and, as explained above, the whole AM
runs under the logged in user, which also helps with simplifying some more code.
* Distributed cache configs are sent separately to the AM.
Because of the delayed initialization of the cached resources in the AM, it
became easier to write the cache config to a separate properties file instead
of bundling it with the rest of the Spark config. This also avoids having
to modify the SparkConf to hide things from the UI.
* Finally, the AM doesn't manage the token manager anymore.
The above changes allow the token manager to be completely handled by the
driver's scheduler backend code also in YARN mode (whether client or cluster),
making it similar to other RMs. To maintain the fix added in SPARK-23361 also
in client mode, the AM now sends an extra message to the driver on initialization
to fetch delegation tokens; and although it might not really be needed, the
driver also keeps the running AM updated when new tokens are created.
Tested in a kerberized cluster with the same tests used to validate SPARK-23361,
in both client and cluster mode. Also tested with a non-kerberized cluster.

I think this may reduce some computation and memory evicting costs especially when required space(`numBytes`) is very big.

This PR upgrades Mockito from 1.10.19 to 2.23.4. The following changes are required.
- Replace `org.mockito.Matchers` with `org.mockito.ArgumentMatchers`
- Replace `anyObject` with `any`
- Replace `getArgumentAt` with `getArgument` and add type annotation.
- Use `isNull` matcher in case of `null` is invoked.
```scala
saslHandler.channelInactive(null);
- verify(handler).channelInactive(any(TransportClient.class));
+ verify(handler).channelInactive(isNull());
```
- Make and use `doReturn` wrapper to avoid [SI-4775](https://issues.scala-lang.org/browse/SI-4775)

Recently, the ability to expose the metrics for YARN Shuffle Service was added as part of [SPARK-18364](https://github.com/apache/spark/pull/22485). We need to add some metrics to be able to determine the number of active connections as well as open connections to the external shuffle service to benchmark network and connection issues on large cluster environments.
Added two more shuffle server metrics for Spark Yarn shuffle service: numRegisteredConnections which indicate the number of registered connections to the shuffle service and numActiveConnections which indicate the number of active connections to the shuffle service at any given point in time.
If these metrics are outputted to a file, we get something like this:
1533674653489 default.shuffleService: Hostname=server1.abc.com, openBlockRequestLatencyMillis_count=729, openBlockRequestLatencyMillis_rate15=0.7110833548897356, openBlockRequestLatencyMillis_rate5=1.657808981793011, openBlockRequestLatencyMillis_rate1=2.2404486061620474, openBlockRequestLatencyMillis_rateMean=0.9242558551196706,

Closes#21664 from caneGuy/zhoukang/fix-noclassdeferror.
Authored-by: zhoukang <zhoukang199191@gmail.com>
Signed-off-by: Sean Owen <sean.owen@databricks.com>
This change hooks up the k8s backed to the updated HadoopDelegationTokenManager,
so that delegation tokens are also available in client mode, and keytab-based token
renewal is enabled.
The change re-works the k8s feature steps related to kerberos so
that the driver does all the credential management and provides all
the needed information to executors - so nothing needs to be added
to executor pods. This also makes cluster mode behave a lot more
similarly to client mode, since no driver-related config steps are run
in the latter case.
The main two things that don't need to happen in executors anymore are:
- adding the Hadoop config to the executor pods: this is not needed
since the Spark driver will serialize the Hadoop config and send
it to executors when running tasks.
- mounting the kerberos config file in the executor pods: this is
not needed once you remove the above. The Hadoop conf sent by
the driver with the tasks is already resolved (i.e. has all the
kerberos names properly defined), so executors do not need access
to the kerberos realm information anymore.
The change also avoids creating delegation tokens unnecessarily.
This means that they'll only be created if a secret with tokens
was not provided, and if a keytab is not provided. In either of
those cases, the driver code will handle delegation tokens: in
cluster mode by creating a secret and stashing them, in client
mode by using existing mechanisms to send DTs to executors.
One last feature: the change also allows defining a keytab with
a "local:" URI. This is supported in client mode (although that's
the same as not saying "local:"), and in k8s cluster mode. This
allows the keytab to be mounted onto the image from a pre-existing
secret, for example.
Finally, the new code always sets SPARK_USER in the driver and
executor pods. This is in line with how other resource managers
behave: the submitting user reflects which user will access
Hadoop services in the app. (With kerberos, that's overridden
by the logged in user.) That user is unrelated to the OS user
the app is running as inside the containers.
Tested:
- client and cluster mode with kinit
- cluster mode with keytab
- cluster mode with local: keytab
- YARN cluster with keytab (to make sure it isn't broken)

This is kind of a followup of https://github.com/apache/spark/pull/23239
The `UnsafeProject` will normalize special float/double values(NaN and -0.0), so the sorter doesn't have to handle it.
However, for consistency and future-proof, this PR proposes to normalize `-0.0` in the prefix comparator, so that it's same with the normal ordering. Note that prefix comparator handles NaN as well.
This is not a bug fix, but a safe guard.

YARN applicationMaster metrics registration introduced in SPARK-24594 causes further registration of static metrics (Codegenerator and HiveExternalCatalog) and of JVM metrics, which I believe do not belong in this context.
This looks like an unintended side effect of using the start method of [[MetricsSystem]].
A possible solution proposed here, is to introduce startNoRegisterSources to avoid these additional registrations of static sources and of JVM sources in the case of YARN applicationMaster metrics (this could be useful for other metrics that may be added in the future).

## What changes were proposed in this pull request?
In `BytesToBytesMap.MapIterator.advanceToNextPage`, We will first lock this `MapIterator` and then `TaskMemoryManager` when going to free a memory page by calling `freePage`. At the same time, it is possibly that another memory consumer first locks `TaskMemoryManager` and then this `MapIterator` when it acquires memory and causes spilling on this `MapIterator`.
So it ends with the `MapIterator` object holds lock to the `MapIterator` object and waits for lock on `TaskMemoryManager`, and the other consumer holds lock to `TaskMemoryManager` and waits for lock on the `MapIterator` object.
To avoid deadlock here, this patch proposes to keep reference to the page to free and free it after releasing the lock of `MapIterator`.

This adds the entire memory used by spark’s executor (as measured by procfs) to the executor metrics. The memory usage is collected from the entire process tree under the executor. The metrics are subdivided into memory used by java, by python, and by other processes, to aid users in diagnosing the source of high memory usage.
The additional metrics are sent to the driver in heartbeats, using the mechanism introduced by SPARK-23429. This also slightly extends that approach to allow one ExecutorMetricType to collect multiple metrics.
Added unit tests and also tested on a live cluster.
