### What changes were proposed in this pull request?
This PR aims the followings.
1. Upgrade from Scala 2.13.3 to 2.13.4 for Apache Spark 3.1
2. Fix exhaustivity issues in both Scala 2.12/2.13 (Scala 2.13.4 requires this for compilation.)
3. Enforce the improved exhaustive check by using the existing Scala 2.13 GitHub Action compilation job.
### Why are the changes needed?
Scala 2.13.4 is a maintenance release for 2.13 line and improves JDK 15 support.
- https://github.com/scala/scala/releases/tag/v2.13.4
Also, it improves exhaustivity check.
- https://github.com/scala/scala/pull/9140 (Check exhaustivity of pattern matches with "if" guards and custom extractors)
- https://github.com/scala/scala/pull/9147 (Check all bindings exhaustively, e.g. tuples components)
### Does this PR introduce _any_ user-facing change?
Yep. Although it's a maintenance version change, it's a Scala version change.
### How was this patch tested?
Pass the CIs and do the manual testing.
- Scala 2.12 CI jobs(GitHub Action/Jenkins UT/Jenkins K8s IT) to check the validity of code change.
- Scala 2.13 Compilation job to check the compilation

### What changes were proposed in this pull request?
This PR cleans up the RPC message flow among the multiple decommission use cases, it includes changes:
* Keep `Worker`'s decommission status be consistent between the case where decommission starts from `Worker` and the case where decommission starts from the `MasterWebUI`: sending `DecommissionWorker` from `Master` to `Worker` in the latter case.
* Change from two-way communication to one-way communication when notifying decommission between driver and executor: it's obviously unnecessary for the executor to acknowledge the decommission status to the driver since the decommission request is from the driver. And it's same in reverse.
* Only send one message instead of two(`DecommissionSelf`/`DecommissionBlockManager`) when decommission the executor: executor and `BlockManager` are in the same JVM.
* Clean up codes around here.

### What changes were proposed in this pull request?
There is only one failed case of `streaming` module in Scala 2.13: `start with non-serializable DStream checkpoint ` in `StreamingContextSuite`.
`StackOverflowError` is thrown here when `SerializationDebugger#visit` method is called.
I found that `inputStreams` and `outputStreams` in `DStreamGraph` can not be matched in `SerializationDebugger#visit` method because `ArrayBuffer` in not `Array` in Scala 2.13.
The main change of this pr is use `mutable.ArraySeq` instead of `ArrayBuffer` to store `inputStreams` and `outputStreams` in `DStreamGraph`, then it can be matched in `SerializationDebugger#visit` method.

### What changes were proposed in this pull request?
The motivation of this PR is to avoid caching the removed decommissioned executors in `TaskSchedulerImpl`. The cache is introduced in https://github.com/apache/spark/pull/29422. The cache will hold the `isHostDecommissioned` info for a while. So if the task `FetchFailure` event comes after the executor loss event, `DAGScheduler` can still get the `isHostDecommissioned` from the cache and unregister the host shuffle map status when the host is decommissioned too.
This PR tries to achieve the same goal without the cache. Instead of saving the `workerLost` in `ExecutorUpdated` / `ExecutorDecommissionInfo` / `ExecutorDecommissionState`, we could save the `hostOpt` directly. When the host is decommissioned or lost too, the `hostOpt` can be a specific host address. Otherwise, it's `None` to indicate that only the executor is decommissioned or lost.
Now that we have the host info, we can also unregister the host shuffle map status when `executorLost` is triggered for the decommissioned executor.
Besides, this PR also includes a few cleanups around the touched code.
### Why are the changes needed?
It helps to unregister the shuffle map status earlier for both decommission and normal executor lost cases.
It also saves memory in `TaskSchedulerImpl` and simplifies the code a little bit.
### Does this PR introduce _any_ user-facing change?
No.
### How was this patch tested?
This PR only refactor the code. The original behaviour should be covered by `DecommissionWorkerSuite`.

### What changes were proposed in this pull request?
Rename `spark.worker.decommission.enabled` to `spark.decommission.enabled` and move it from `org.apache.spark.internal.config.Worker` to `org.apache.spark.internal.config.package`.
### Why are the changes needed?
Decommission has been supported in Standalone and k8s yet and may be supported in Yarn(https://github.com/apache/spark/pull/27636) in the future. Therefore, the switch configuration should have the highest hierarchy rather than belongs to Standalone's Worker. In other words, it should be independent of the cluster managers.
### Does this PR introduce _any_ user-facing change?
No, as the decommission feature hasn't been released.

### What changes were proposed in this pull request?
If graceful decommissioning is enabled, Spark's dynamic scaling uses this instead of directly killing executors.
### Why are the changes needed?
When scaling down Spark we should avoid triggering recomputes as much as possible.
### Does this PR introduce _any_ user-facing change?
Hopefully their jobs run faster or at the same speed. It also enables experimental shuffle service free dynamic scaling when graceful decommissioning is enabled (using the same code as the shuffle tracking dynamic scaling).
### How was this patch tested?
For now I've extended the ExecutorAllocationManagerSuite for both core & streaming.

### What is changed?
This pull request adds the ability to migrate shuffle files during Spark's decommissioning. The design document associated with this change is at https://docs.google.com/document/d/1xVO1b6KAwdUhjEJBolVPl9C6sLj7oOveErwDSYdT-pE .
To allow this change the `MapOutputTracker` has been extended to allow the location of shuffle files to be updated with `updateMapOutput`. When a shuffle block is put, a block update message will be sent which triggers the `updateMapOutput`.
Instead of rejecting remote puts of shuffle blocks `BlockManager` delegates the storage of shuffle blocks to it's shufflemanager's resolver (if supported). A new, experimental, trait is added for shuffle resolvers to indicate they handle remote putting of blocks.
The existing block migration code is moved out into a separate file, and a producer/consumer model is introduced for migrating shuffle files from the host as quickly as possible while not overwhelming other executors.
### Why are the changes needed?
Recomputting shuffle blocks can be expensive, we should take advantage of our decommissioning time to migrate these blocks.
### Does this PR introduce any user-facing change?
This PR introduces two new configs parameters, `spark.storage.decommission.shuffleBlocks.enabled` & `spark.storage.decommission.rddBlocks.enabled` that control which blocks should be migrated during storage decommissioning.
### How was this patch tested?
New unit test & expansion of the Spark on K8s decom test to assert that decommisioning with shuffle block migration means that the results are not recomputed even when the original executor is terminated.
This PR is a cleaned-up version of the previous WIP PR I made https://github.com/apache/spark/pull/28331 (thanks to attilapiros for his very helpful reviewing on it :)).

### What changes were proposed in this pull request?
This PR will remove references to these "blacklist" and "whitelist" terms besides the blacklisting feature as a whole, which can be handled in a separate JIRA/PR.
This touches quite a few files, but the changes are straightforward (variable/method/etc. name changes) and most quite self-contained.
### Why are the changes needed?
As per discussion on the Spark dev list, it will be beneficial to remove references to problematic language that can alienate potential community members. One such reference is "blacklist" and "whitelist". While it seems to me that there is some valid debate as to whether these terms have racist origins, the cultural connotations are inescapable in today's world.
### Does this PR introduce _any_ user-facing change?
In the test file `HiveQueryFileTest`, a developer has the ability to specify the system property `spark.hive.whitelist` to specify a list of Hive query files that should be tested. This system property has been renamed to `spark.hive.includelist`. The old property has been kept for compatibility, but will log a warning if used. I am open to feedback from others on whether keeping a deprecated property here is unnecessary given that this is just for developers running tests.
### How was this patch tested?
Existing tests should be suitable since no behavior changes are expected as a result of this PR.

### What changes were proposed in this pull request?
* Pagination Support is added to all tables of streaming page in spark web UI.
For adding pagination support, existing classes from #7399 were used.
* Earlier streaming page has two tables `Active Batches` and `Completed Batches`. Now, we will have three tables `Running Batches`, `Waiting Batches` and `Completed Batches`. If we have large number of waiting and running batches then keeping track in a single table is difficult. Also other pages have different table for different type type of data.
* Earlier empty tables were shown. Now only non-empty tables will be shown.
`Active Batches` table used to show details of waiting batches followed by running batches.
### Why are the changes needed?
Pagination will allow users to analyse the table in much better way. All spark web UI pages support pagination apart from streaming pages, so this will add consistency as well. Also it might fix the potential OOM errors that can arise.
### Does this PR introduce _any_ user-facing change?
Yes. `Active Batches` table is split into two tables `Running Batches` and `Waiting Batches`. Pagination Support is added to the all the tables. Every other functionality is unchanged.

### What changes were proposed in this pull request?
Refactor `streaming-page.js` by making on-click timeline action customizable.
### Why are the changes needed?
In the current implementation, `streaming-page.js` is used from Streaming page and Structured Streaming page but the implementation of the on-click timeline action is strongly dependent on Streamng page.
Structured Streaming page doesn't define the on-click action for now but it's better to remove the dependncy for the future.
Originally, I make this change to fix `SPARK-31128` but #27883 resolved it.
So, now this is just for refactoring.
### Does this PR introduce any user-facing change?
No.
### How was this patch tested?
Manual tests with following code and confirmed there are no regression and no error in the debug console in Firefox.
For Structured Streaming:
```
spark.readStream.format("socket").options(Map("host"->"localhost", "port"->"8765")).load.writeStream.format("console").start
```
And then, visited Structured Streaming page and there were no error in the debug console when I clicked a point in the timeline.
For Spark Streaming:
```
import org.apache.spark.streaming._
val ssc = new StreamingContext(sc, Seconds(1))
ssc.socketTextStream("localhost", 8765)
dstream.foreachRDD(rdd => rdd.foreach(println))
ssc.start
```
And then, visited Streaming page and confirmed scrolling down and hilighting work well and there were no error in the debug console when I clicked a point in the timeline.

### What changes were proposed in this pull request?
Spark's Web UI is using an older version of Bootstrap (v. 2.3.2) for the portal pages. Bootstrap 2.x was moved to EOL in Aug 2013 and Bootstrap 3.x was moved to EOL in July 2019 (https://github.com/twbs/release). Older versions of Bootstrap are also getting flagged in security scans for various CVEs:
https://snyk.io/vuln/SNYK-JS-BOOTSTRAP-72889https://snyk.io/vuln/SNYK-JS-BOOTSTRAP-173700https://snyk.io/vuln/npm:bootstrap:20180529https://snyk.io/vuln/npm:bootstrap:20160627
I haven't validated each CVE, but it would be nice to resolve any potential issues and get on a supported release.
The bad news is that there have been quite a few changes between Bootstrap 2 and Bootstrap 4. I've tried updating the library, refactoring/tweaking the CSS and JS to maintain a similar appearance and functionality, and testing the UI for functionality and appearance. This is a fairly large change so I'm sure additional testing and fixes will be needed.
### How was this patch tested?
This has been manually tested, but there is a ton of functionality and there are many pages and detail pages so it is very possible bugs introduced from the upgrade were missed. Additional testing and feedback is welcomed. If it appears a whole page was missed let me know and I'll take a pass at addressing that page/section.

### What changes were proposed in this pull request?
This is another PR for stage level scheduling. In particular this adds changes to the dynamic allocation manager and the scheduler backend to be able to track what executors are needed per ResourceProfile. Note the api is still private to Spark until the entire feature gets in, so this functionality will be there but only usable by tests for profiles other then the DefaultProfile.
The main changes here are simply tracking things on a ResourceProfile basis as well as sending the executor requests to the scheduler backend for all ResourceProfiles.
I introduce a ResourceProfileManager in this PR that will track all the actual ResourceProfile objects so that we can keep them all in a single place and just pass around and use in datastructures the resource profile id. The resource profile id can be used with the ResourceProfileManager to get the actual ResourceProfile contents.
There are various places in the code that use executor "slots" for things. The ResourceProfile adds functionality to keep that calculation in it. This logic is more complex then it should due to standalone mode and mesos coarse grained not setting the executor cores config. They default to all cores on the worker, so calculating slots is harder there.
This PR keeps the functionality to make the cores the limiting resource because the scheduler still uses that for "slots" for a few things.
This PR does also add the resource profile id to the Stage and stage info classes to be able to test things easier. That full set of changes will come with the scheduler PR that will be after this one.
The PR stops at the scheduler backend pieces for the cluster manager and the real YARN support hasn't been added in this PR, that again will be in a separate PR, so this has a few of the API changes up to the cluster manager and then just uses the default profile requests to continue.
The code for the entire feature is here for reference: https://github.com/apache/spark/pull/27053/files although it needs to be upmerged again as well.
### Why are the changes needed?
Needed for stage level scheduling feature.
### Does this PR introduce any user-facing change?
No user facing api changes added here.
### How was this patch tested?
Lots of unit tests and manually testing. I tested on yarn, k8s, standalone, local modes. Ran both failure and success cases.

### What changes were proposed in this pull request?
Executor's heartbeat will send synchronously to BlockManagerMaster to let it know that the block manager is still alive. In a heavy cluster, it will timeout and cause block manager re-register unexpected.
This improvement will separate a heartbeat endpoint from the driver endpoint. In our production environment, this was really helpful to prevent executors from unstable up and down.
### Why are the changes needed?
`BlockManagerMasterEndpoint` handles many events from executors like `RegisterBlockManager`, `GetLocations`, `RemoveShuffle`, `RemoveExecutor` etc. In a heavy cluster/app, it is always busy. The `BlockManagerHeartbeat` event also was handled in this endpoint. We found it may timeout when it's busy. So we add a new endpoint `BlockManagerMasterHeartbeatEndpoint` to handle heartbeat separately.

No.

### What changes were proposed in this pull request?
The `assertEquals` method of JUnit Assert requires the first parameter to be the expected value. In this PR, I propose to change the order of parameters when the expected value is passed as the second parameter.
### Why are the changes needed?
Wrong order of assert parameters confuses when the assert fails and the parameters have special string representation. For example:
```java
assertEquals(input1.add(input2), new CalendarInterval(5, 5, 367200000000L));
```
```
java.lang.AssertionError:
Expected :interval 5 months 5 days 101 hours
Actual :interval 5 months 5 days 102 hours
```
