### What changes were proposed in this pull request?
I push this PR as I could not re-open the stale one https://github.com/apache/spark/pull/20665 .
As for Yarn or Kubernetes, Mesos users should be able to specify priority queues to define a workload management policy for queued drivers in the Mesos Cluster Dispatcher.
This would ensure scheduling order while enqueuing Spark applications for a Mesos cluster.
### Why are the changes needed?
Currently, submitted drivers are kept in order of their submission: the first driver added to the queue will be the first one to be executed (FIFO), regardless of their priority.
See https://issues.apache.org/jira/projects/SPARK/issues/SPARK-23499 for more details.
### Does this PR introduce _any_ user-facing change?
The MesosClusterDispatcher UI shows now Spark jobs along with the queue to which they are submitted.
### How was this patch tested?
Unit tests.
Also, this feature has been in production for 3 years now as we use a modified Spark 2.4.0 since then.

### What changes were proposed in this pull request?
This is an improvement, we mount all the user specific configuration files(except the templates and spark properties files) from `SPARK_CONF_DIR` at the point of spark-submit, to both executor and driver pods. Currently, only `spark.properties` is mounted, only on driver.
### Why are the changes needed?
`SPARK_CONF_DIR` hosts several configuration files, for example,
1) `spark-defaults.conf` - containing all the spark properties.
2) `log4j.properties` - Logger configuration.
3) `core-site.xml` - Hadoop related configuration.
4) `fairscheduler.xml` - Spark's fair scheduling policy at the job level.
5) `metrics.properties` - Spark metrics.
6) Any user specific - library or framework specific configuration file.
At the moment, we can cannot propagate these files to the driver and executor configuration directory.
There is a design doc, with more details, and this patch is currently providing a reference implementation. Please take a look at the doc and comment, how we can improve. [google docs link to the doc](https://bit.ly/spark-30985)
### Further scope
Support user defined configMaps.
### Does this PR introduce any user-facing change?
Yes, previously the user configuration files(e.g. hdfs-site.xml, log4j.properties etc...) were not propagated by default, now after this patch it is propagated to driver and executor pods' `SPARK_CONF_DIR`.
### How was this patch tested?
Added tests.
Also manually tested, by deploying it to a minikube cluster and observing the additional configuration files were present, and taking effect. For example, changes to log4j.properties was properly applied to executors.

This is a follow-up fix for the failing tests in `YarnShuffleServiceSuite.java`. This java class was introduced in https://github.com/apache/spark/pull/30062. The tests in the class fail when run with hadoop-2.7 profile:
```

```
A test suit for `YarnShuffleService` did exist here:
`resource-managers/yarn/src/test/scala/org/apache/spark/network/yarn/YarnShuffleServiceSuite.scala`
I missed this when I created `common/network-yarn/src/test/java/org/apache/spark/network/yarn/YarnShuffleServiceSuite.java`. Moving all the new tests to the earlier test suite fixes the failures with hadoop-2.7 even though why this happened is not clear.
### Why are the changes needed?
The newly added tests are failing when run with hadoop profile 2.7
### Does this PR introduce _any_ user-facing change?
No
### How was this patch tested?
Ran the unit tests with the default profile as well as hadoop 2.7 profile.
`build/mvn test -Dtest=none -DwildcardSuites=org.apache.spark.network.yarn.YarnShuffleServiceSuite -Phadoop-2.7 -Pyarn`

- executor state kept across NM restart
- removed applications should not be in registered executor file
- shuffle service should be robust to corrupt registered executor file
- get correct recovery path
- moving recovery file from NM local dir to recovery path
- service throws error if cannot start
- recovery db should not be created if NM recovery is not enabled

### What changes were proposed in this pull request?
This adds support for Stage level scheduling to kubernetes. Kubernetes can support dynamic allocation via the shuffle tracking option which means we can support stage level scheduling by getting new executors.
The main changes here are having the k8s cluster manager pass the resource profile id into the executors and then the ExecutorsPodsAllocator has to request executors based on the individual resource profiles. I tried to keep code changes here to a minimum. I specifically choose to leave the ExecutorPodsSnapshot the way it was and construct the resource profile to pod states on the fly, with a fast path when not using other resource profiles, to keep the impact to a minimum. This results in the main changes required are just wrapping the allocation logic in a for loop over each profile. The other main change is in the basic feature step we have to look at the resources in the ResourceProfile to request pods with the correct resources. Much of the other logic like in the executor life cycle manager doesn't need to be resource profile.
This also adds support for [SPARK-32661]Spark executors on K8S should request extra memory for off-heap allocations because the stage level scheduling api has support for this and it made sense to make consistent with YARN. This was started with PR https://github.com/apache/spark/pull/29477 but never updated so I just did it here. To do this I moved a few functions around that were now used by both YARN and kubernetes so you will see some changes in Utils.
### Why are the changes needed?
Add the feature to Kubernetes based on customer feedback.
### Does this PR introduce _any_ user-facing change?
Yes the feature now works with K8s, but not underlying API changes.
### How was this patch tested?
Tested manually on kubernetes cluster and with unit tests.

### What changes were proposed in this pull request?
Currently when run in `cluster` mode on YARN, the Spark `yarn.Client` will print out the application report into the logs, to be easily viewed by users. For example:
```
INFO yarn.Client:
client token: Token { kind: YARN_CLIENT_TOKEN, service: }
diagnostics: N/A
ApplicationMaster host: X.X.X.X
ApplicationMaster RPC port: 0
queue: default
start time: 1602782566027
final status: UNDEFINED
tracking URL: http://hostname:8888/proxy/application_<id>/
user: xkrogen
```
I propose adding, alongside the application report, some additional lines like:
```
Driver Logs (stdout): http://hostname:8042/node/containerlogs/container_<id>/xkrogen/stdout?start=-4096
Driver Logs (stderr): http://hostname:8042/node/containerlogs/container_<id>/xkrogen/stderr?start=-4096
```
This information isn't contained in the `ApplicationReport`, so it's necessary to query the ResourceManager REST API. For now I have added this as an always-on feature, but if there is any concern about adding this REST dependency, I think hiding this feature behind an off-by-default flag is reasonable.
### Why are the changes needed?
Typically, the tracking URL can be used to find the logs of the ApplicationMaster/driver while the application is running. Later, the Spark History Server can be used to track this information down, using the stdout/stderr links on the Executors page.
However, in the situation when the driver crashed _before_ writing out a history file, the SHS may not be aware of this application, and thus does not contain links to the driver logs. When this situation arises, it can be difficult for users to debug further, since they can't easily find their driver logs.
It is possible to reach the logs by using the `yarn logs` commands, but the average Spark user isn't aware of this and shouldn't have to be.
With this information readily available in the logs, users can quickly jump to their driver logs, even if it crashed before the SHS became aware of the application. This has the additional benefit of providing a quick way to access driver logs, which often contain useful information, in a single click (instead of navigating through the Spark UI).
### Does this PR introduce _any_ user-facing change?
Yes, some additional print statements will be created in the application report when using YARN in cluster mode.
### How was this patch tested?
Added unit tests for the parsing logic in `yarn.ClientSuite`. Also tested against a live cluster. When the driver is running:
```
INFO Client: Application report for application_XXXXXXXXX_YYYYYY (state: RUNNING)
INFO Client:
client token: Token { kind: YARN_CLIENT_TOKEN, service: }
diagnostics: N/A
ApplicationMaster host: host.example.com
ApplicationMaster RPC port: ######
queue: queue_name
start time: 1604529046091
final status: UNDEFINED
tracking URL: http://host.example.com:8080/proxy/application_XXXXXXXXX_YYYYYY/
user: xkrogen
Driver Logs (stdout): http://host.example.com:8042/node/containerlogs/container_e07_XXXXXXXXX_YYYYYY_01_000001/xkrogen/stdout?start=-4096
Driver Logs (stderr): http://host.example.com:8042/node/containerlogs/container_e07_XXXXXXXXX_YYYYYY_01_000001/xkrogen/stderr?start=-4096
INFO Client: Application report for application_XXXXXXXXX_YYYYYY (state: RUNNING)
```
I confirmed that when the driver has not yet launched, the report does not include the two Driver Logs items. Will omit the output here for brevity since it looks the same.

### What changes were proposed in this pull request?
this PR renames the blacklisting feature. I ended up using "excludeOnFailure" or "excluded" in most cases but there is a mix. I renamed the BlacklistTracker to HealthTracker, but for the TaskSetBlacklist HealthTracker didn't make sense to me since its not the health of the taskset itself but rather tracking the things its excluded on so I renamed it to be TaskSetExcludeList. Everything else I tried to use the context and in most cases excluded made sense. It made more sense to me then blocked since you are basically excluding those executors and nodes from scheduling tasks on them. Then can be unexcluded later after timeouts and such. The configs I changed the name to use excludeOnFailure which I thought explained it.
I unfortunately couldn't get rid of some of them because its part of the event listener and history files. To keep backwards compatibility I kept the events and some of the parsing so that the history server would still properly read older history files. It is not forward compatible though - meaning a new application write the "Excluded" events so the older history server won't properly read display them as being blacklisted.
A few of the files below are showing up as deleted and recreated even though I did a git mv on them. I'm not sure why.

get rid of problematic language
### Does this PR introduce _any_ user-facing change?
Config name changes but the old configs still work but are deprecated.

Signed-off-by: Dongjoon Hyun <dhyun@apple.com>
### What changes were proposed in this pull request?
Make pod allocation executor timeouts configurable. Keep all known pods in mind when allocating executors to avoid over-allocating if the pending time is much higher than the allocation interval.
This PR increases the default wait time to 600s from the current 60s.
Since nodes can now remain "pending" for long periods of time, we allow additional batches to be scheduled during pending allocation but keep the total number of pods in account.
### Why are the changes needed?
The current executor timeouts do not match that of all real world clusters especially under load. While this can be worked around by increasing the allocation batch delay, that will decrease the speed at which the total number of executors will be able to be requested.
The increase in default timeout is needed to handle real-world testing environments I've encountered on moderately busy clusters and K8s clusters with their own underlying dynamic scale-up of hardware (e.g. GKE, EKS, etc.)
### Does this PR introduce _any_ user-facing change?
Yes new configuration property

Handle executor failure with multiple containers
Added a spark property spark.kubernetes.executor.checkAllContainers,
with default being false. When it's true, the executor snapshot will
take all containers in the executor into consideration when deciding
whether the executor is in "Running" state, if the pod restart policy is
"Never". Also, added the new spark property to the doc.
### What changes were proposed in this pull request?
Checking of all containers in the executor pod when reporting executor status, if the `spark.kubernetes.executor.checkAllContainers` property is set to true.
### Why are the changes needed?
Currently, a pod remains "running" as long as there is at least one running container. This prevents Spark from noticing when a container has failed in an executor pod with multiple containers. With this change, user can configure the behavior to be different. Namely, if any container in the executor pod has failed, either the executor process or one of its sidecars, the pod is considered to be failed, and it will be rescheduled.
### Does this PR introduce _any_ user-facing change?
Yes, new spark property added.
User is now able to choose whether to turn on this feature using the `spark.kubernetes.executor.checkAllContainers` property.
### How was this patch tested?
Unit test was added and all passed.
I tried to run integration test by following the instruction [here](https://spark.apache.org/developer-tools.html) (section "Testing K8S") and also [here](https://github.com/apache/spark/blob/master/resource-managers/kubernetes/integration-tests/README.md), but I wasn't able to run it smoothly as it fails to talk with minikube cluster. Maybe it's because my minikube version is too new (I'm using v1.13.1)...? Since I've been trying it for two days and still can't make it work, I decided to submit this PR and hopefully the Jenkins test will pass.

### What changes were proposed in this pull request?
This PR proposes to exclude `org.apache.hadoop:hadoop-yarn-server-resourcemanager:jar:tests` from `hadoop-yarn-server-tests` when we use Hadoop 2 profile.
For some reasons, after SBT 1.3 upgrade at SPARK-21708, SBT starts to pull the dependencies of 'hadoop-yarn-server-tests' with 'tests' classifier:
```
org/apache/hadoop/hadoop-common/2.7.4/hadoop-common-2.7.4-tests.jar
org/apache/hadoop/hadoop-yarn-common/2.7.4/hadoop-yarn-common-2.7.4-tests.jar
org/apache/hadoop/hadoop-yarn-server-resourcemanager/2.7.4/hadoop-yarn-server-resourcemanager-2.7.4-tests.jar
```
these were not pulled before the upgrade.
This specific `hadoop-yarn-server-resourcemanager-2.7.4-tests.jar` causes the problem (SPARK-33104)
1. When the test case creates the Hadoop configuration here,
cc06266ade/core/src/main/scala/org/apache/spark/deploy/SparkHadoopUtil.scala (L122)
2. Such jars above have higher precedence in the class path, instead of the specified custom `core-site.xml` in the test:
e93b8f02cd/resource-managers/yarn/src/main/scala/org/apache/spark/deploy/yarn/Client.scala (L1375)
3. Later, `core-site.xml` in the jar is picked instead in Hadoop's `Configuration`:
Before this fix:
```
jar:file:/.../https/maven-central.storage-download.googleapis.com/maven2/org/apache/hadoop/
hadoop-yarn-server-resourcemanager/2.7.4/hadoop-yarn-server-resourcemanager-2.7.4-tests.jar!/core-site.xml
```
After this fix:
```
file:/.../spark/resource-managers/yarn/target/org.apache.spark.deploy.yarn.YarnClusterSuite/
org.apache.spark.deploy.yarn.YarnClusterSuite-localDir-nm-0_0/
usercache/.../filecache/10/__spark_conf__.zip/__hadoop_conf__/core-site.xml
```
4. the `core-site.xml` in the jar of course does not contain:
2cfd215dc4/resource-managers/yarn/src/test/scala/org/apache/spark/deploy/yarn/YarnClusterSuite.scala (L133-L141)
and the specific test fails.
This PR uses some kind of hacky approach. It was excluded from 'hadoop-yarn-server-tests' with 'tests' classifier, and then added back as a proper dependency (when Hadoop 2 profile is used). In this way, SBT does not pull `hadoop-yarn-server-resourcemanager` with `tests` classifier anymore.
### Why are the changes needed?
To make the build pass. This is a blocker.
### Does this PR introduce _any_ user-facing change?
No, test-only.
### How was this patch tested?
Manually tested and debugged:
```bash

### 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.

(Note the diagrams only counts those RPC calls that needed to go through the network. Local RPC calls are not counted here.)
After this change, We reduced 6 original RPC calls and added one more RPC call for keeping the consistent decommission status for the Worker. And the RPC flow becomes more clear.

### What changes were proposed in this pull request?
This switches Spark to use shaded Hadoop clients, namely hadoop-client-api and hadoop-client-runtime, for Hadoop 3.x. For Hadoop 2.7, we'll still use the same modules such as hadoop-client.
In order to still keep default Hadoop profile to be hadoop-3.2, this defines the following Maven properties:
```
hadoop-client-api.artifact
hadoop-client-runtime.artifact
hadoop-client-minicluster.artifact
```
which default to:
```
hadoop-client-api
hadoop-client-runtime
hadoop-client-minicluster
```
but all switch to `hadoop-client` when the Hadoop profile is hadoop-2.7. A side affect from this is we'll import the same dependency multiple times. For this I have to disable Maven enforcer `banDuplicatePomDependencyVersions`.
Besides above, there are the following changes:
- explicitly add a few dependencies which are imported via transitive dependencies from Hadoop jars, but are removed from the shaded client jars.
- removed the use of `ProxyUriUtils.getPath` from `ApplicationMaster` which is a server-side/private API.
- modified `IsolatedClientLoader` to exclude `hadoop-auth` jars when Hadoop version is 3.x. This change should only matter when we're not sharing Hadoop classes with Spark (which is _mostly_ used in tests).
### Why are the changes needed?
This serves two purposes:
- to unblock Spark from upgrading to Hadoop 3.2.2/3.3.0+. Latest Hadoop versions have upgraded to use Guava 27+ and in order to adopt the latest Hadoop versions in Spark, we'll need to resolve the Guava conflicts. This takes the approach by switching to shaded client jars provided by Hadoop.
- avoid pulling 3rd party dependencies from Hadoop and avoid potential future conflicts.
### Does this PR introduce _any_ user-facing change?
When people use Spark with `hadoop-provided` option, they should make sure class path contains `hadoop-client-api` and `hadoop-client-runtime` jars. In addition, they may need to make sure these jars appear before other Hadoop jars in the order. Otherwise, classes may be loaded from the other non-shaded Hadoop jars and cause potential conflicts.
### How was this patch tested?
Relying on existing tests.

I think this was broken when Python 2 was dropped but was not caught because this specific test does not run when there's no change in YARN codes. See also https://github.com/apache/spark/pull/29843#issuecomment-712540024
The root cause seems like the paths are different, see https://github.com/apache/spark/pull/29843#pullrequestreview-502595199. I _think_ Jenkins uses a different Python executable via Anaconda and the executor side does not know where it is for some reasons.
This PR proposes to fix it just by explicitly specifying the absolute path for Python executable so the tests should pass in any environment.

This PR aims to detect duplicate `mountPath`s and stop the job.
### Why are the changes needed?
If there is a conflict on `mountPath`, the pod is created and repeats the following error messages and keeps running. Spark job should not keep running and wasting the cluster resources. We had better fail at Spark side.
```
$ k get pod -l 'spark-role in (driver,executor)'

### What changes were proposed in this pull request?
This PR aims to use `openjdk:11-jre-slim` as default in K8s Dockerfile.
### Why are the changes needed?
Although Apache Spark supports both Java8/Java11, there is a difference.
1. Java8-built distribution can run both Java8/Java11
2. Java11-built distribution can run on Java11, but not Java8.
In short, we had better use Java11 in Dockerfile to embrace both cases without any issues.
### Does this PR introduce _any_ user-facing change?
Yes. This will remove the change of user frustration when they build with JDK11 and build the image without overriding Java base image.

### What changes were proposed in this pull request?
If a block is removed between discovery to transfer fo the block, we short circuit that block and remove it from the list to transfer and increment the transferred blocks. This is complicated since both RPC errors and local read errors may be reported with the same exception class.
### Why are the changes needed?
Slow shuffle refreshes could waste time when decommissioning has already finished. Decommissioning might avoid transferring some some blocks to an otherwise live host which is marked as "full" if a deleted block fails to transfer to that host.

No.

### What changes were proposed in this pull request?
This is the first patch for SPIP SPARK-30602 for push-based shuffle.
Summary of changes:
* Introduce new API in ExternalBlockStoreClient to push blocks to a remote shuffle service.
* Leveraging the streaming upload functionality in SPARK-6237, it also enables the ExternalBlockHandler to delegate the handling of block push requests to MergedShuffleFileManager.
* Propose the API for MergedShuffleFileManager, where the core logic on the shuffle service side to handle block push requests is defined. The actual implementation of this API is deferred into a later RB to restrict the size of this PR.
* Introduce OneForOneBlockPusher to enable pushing blocks to remote shuffle services in shuffle RPC layer.
* New protocols in shuffle RPC layer to support the functionalities.
### Why are the changes needed?

### Does this PR introduce _any_ user-facing change?
No.
### How was this patch tested?
Added unit tests.
The reference PR with the consolidated changes covering the complete implementation is also provided in SPARK-30602.

### What changes were proposed in this pull request?
This PR aims to protect the executor pod request or pending pod during executor idle timeout.
### Why are the changes needed?
In case of dynamic allocation, Apache Spark K8s `ExecutorPodsAllocator` cancels the pod requests or pending pods too eagerly. Like the following example, `ExecutorPodsAllocator` received the new total executor adjust request rapidly in two minutes. Sometimes, it's called 3 times in a single second. It repeats `request` and `delete` on that request or pending pod frequently. This PR is reusing `spark.dynamicAllocation.executorIdleTimeout (default: 60s)` to keep the pod request or pending pod.

The solution is to expand the stack size of a thread in the test from 32KB to 256KB.
Currently, the stack size is specified as 32KB but the actual stack size can be greater than 32KB.
According to the code of Hotspot, the minimum stack size is prefer to the specified size.
Java 8: https://hg.openjdk.java.net/jdk8u/jdk8u/hotspot/file/c92ba514724d/src/os/linux/vm/os_linux.cpp#l900
Java 11: https://hg.openjdk.java.net/jdk-updates/jdk11u/file/73edf743a93a/src/hotspot/os/posix/os_posix.cpp#l1555
For Linux on x86_64, the minimum stack size seems to be 224KB and 136KB for Java 8 and Java 11 respectively. So, the actual stack size should be 224KB rather than 32KB for Java 8 on x86_64/Linux.
As the test passes for Java 8 but doesn't for Java 11, 224KB is enough while 136KB is not.
So I think specifing 256KB is reasonable for the new stack size.
### Why are the changes needed?
To pass the test for Java 11.
### Does this PR introduce _any_ user-facing change?
No.
### How was this patch tested?
Following command with Java 11.

**NOTE**
This should be used carefully because Apache Spark doesn't delete driver pod automatically. Since the driver PVC shares the lifecycle of driver pod, it will exist after the job completion until the pod deletion. However, if the users are already using pre-populated PVCs, this isn't a regression at all in terms of the cost.

### What changes were proposed in this pull request?
When I tried to verify that the `resource-managers/yarn` module passed all UTs in Scala 2.13 , I found that there is a
issue related to classpath order maybe blocked the UTs because there are more than one `servlet-api` dependency in spark now:
- One is `javax.servlet:javax.servlet-api:3.10:compile` config in core/pom.xml,
- The other is `jakarta.servlet:jakarta.servlet-api:4.0.3:test` cascaded by `org.glassfish.jersey.test-framework.providers`
we can use `mvn dependency:tree` to check it .
So when we execute `resource-managers/yarn` module test use
```
mvn clean test -pl resource-managers/yarn -Pyarn
```
or
```
mvn clean test -pl resource-managers/yarn -Pyarn -Pscala-2.13
```
and if the position of `javax.servlet-api` in the in classpath is before `jakarta.servlet-api`, there are some cases failed in `YarnClusterSuite`, `YarnShuffleIntegrationSuite` and `YarnShuffleAuthSuite`.
The failed reason as follow:
```
20/09/18 19:14:07.486 launcher-proc-1 INFO YarnClusterDriver: Exception in thread "main" java.lang.ExceptionInInitializerError
...
20/09/18 19:14:07.486 launcher-proc-1 INFO YarnClusterDriver: Caused by: java.lang.SecurityException: class "javax.servlet.http.HttpSessionIdListener"'s signer information does not match signer information of other classes in the same package

### What changes were proposed in this pull request?
Disallow `FileSystem.get(Configuration conf)` in Scala style check by default and suggest developers use `FileSystem.get(URI uri, Configuration conf)` or `Path.getFileSystem()` instead.
### Why are the changes needed?
The method `FileSystem.get(Configuration conf)` will return a default FileSystem instance if the conf `fs.file.impl` is not set. This can cause file not found exception on reading a target path of non-default file system, e.g. S3. It is hard to discover such a mistake via unit tests.
If we disallow it in Scala style check by default and suggest developers use `FileSystem.get(URI uri, Configuration conf)` or `Path.getFileSystem(Configuration conf)`, we can reduce potential regression and PR review effort.

### 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.

### 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?
This PR aims to drop Python 2.7, 3.4 and 3.5.
Roughly speaking, it removes all the widely known Python 2 compatibility workarounds such as `sys.version` comparison, `__future__`. Also, it removes the Python 2 dedicated codes such as `ArrayConstructor` in Spark.
### Why are the changes needed?
1. Unsupport EOL Python versions
2. Reduce maintenance overhead and remove a bit of legacy codes and hacks for Python 2.
3. PyPy2 has a critical bug that causes a flaky test, SPARK-28358 given my testing and investigation.
4. Users can use Python type hints with Pandas UDFs without thinking about Python version
5. Users can leverage one latest cloudpickle, https://github.com/apache/spark/pull/28950. With Python 3.8+ it can also leverage C pickle.
### Does this PR introduce _any_ user-facing change?
Yes, users cannot use Python 2.7, 3.4 and 3.5 in the upcoming Spark version.
### How was this patch tested?

### What changes were proposed in this pull request?
This change replaces the world slave with alternatives matching the context.
### Why are the changes needed?
There is no need to call things slave, we might as well use better clearer names.
### Does this PR introduce _any_ user-facing change?
Yes, the ouput JSON does change. To allow backwards compatibility this is an additive change.
The shell scripts for starting & stopping workers are renamed, and for backwards compatibility old scripts are added to call through to the new ones while printing a deprecation message to stderr.
### How was this patch tested?
Existing tests.

## What changes were proposed in this pull request?
When a Spark Job launched in Cluster mode with Yarn, Application Master sets spark.ui.port port to 0 which means Driver's web UI gets any random port even if we want to explicitly set the Port range for Driver's Web UI
## Why are the changes needed?
We access Spark Web UI via Knox Proxy, and there are firewall restrictions due to which we can not access Spark Web UI since Web UI port range gets random port even if we set explicitly.
This Change will check if there is a specified port range explicitly mentioned so that it does not assign a random port.

No

## What changes were proposed in this pull request?
To allow alternatives to serviceaccounts
### Why are the changes needed?
Although we provide some authentication configuration, such as spark.kubernetes.authenticate.driver.mounted.oauthTokenFile, spark.kubernetes.authenticate.driver.mounted.caCertFile, etc.
But there is a bug as we forced the service account so when we use one of them, driver still use the KUBERNETES_SERVICE_ACCOUNT_TOKEN_PATH file, and the error look like bellow:
the KUBERNETES_SERVICE_ACCOUNT_TOKEN_PATH serviceAccount not exists
### Does this PR introduce any user-facing change?
Yes user can now use `spark.kubernetes.authenticate.driver.mounted.caCertFile`
or token file by `spark.kubernetes.authenticate.driver.mounted.oauthTokenFile`
## How was this patch tested?
Manually passed the certificates using `spark.kubernetes.authenticate.driver.mounted.caCertFile`
or token file by `spark.kubernetes.authenticate.driver.mounted.oauthTokenFile` if there is no default service account available.

#31029 # What changes were proposed in this pull request?
In YarnSchedulerBackend, we should avoid using the global execution context for its Future. Otherwise if user's Spark application also uses global execution context for its Future, the user is facing indeterministic behavior in terms of the thread's context class loader.
### Why are the changes needed?
When running tpc-ds test (https://github.com/databricks/spark-sql-perf), occasionally we see error related to class not found:
2020-02-04 20:00:26,673 ERROR yarn.ApplicationMaster: User class threw exception: scala.ScalaReflectionException: class com.databricks.spark.sql.perf.ExperimentRun in JavaMirror with
sun.misc.Launcher$AppClassLoader28ba21f3 of type class sun.misc.Launcher$AppClassLoader with classpath [...]
and parent being sun.misc.Launcher$ExtClassLoader3ff5d147 of type class sun.misc.Launcher$ExtClassLoader with classpath [...]
and parent being primordial classloader with boot classpath [...] not found.
This is the root cause for the problem:
Spark driver starts ApplicationMaster in the main thread, which starts a user thread and set MutableURLClassLoader to that thread's ContextClassLoader.
userClassThread = startUserApplication()
The main thread then setup YarnSchedulerBackend RPC endpoints, which handles these calls using scala Future with the default global ExecutionContext:
doRequestTotalExecutors
doKillExecutors
So for the main thread and user thread, whoever starts the future first get a chance to set ContextClassLoader to the default thread pool:
- If main thread starts a future to handle doKillExecutors() before user thread does then the default thread pool thread's ContextClassLoader would be the default (AppClassLoader).
- If user thread starts a future first then the thread pool thread will have MutableURLClassLoader.
Note that only MutableURLClassLoader can load user provided class for the Spark app, you will see errors related to class not found if the ContextClassLoader is AppClassLoader.

### What changes were proposed in this pull request?
If a Spark distribution has built-in hadoop runtime, Spark will not populate the hadoop classpath from `yarn.application.classpath` and `mapreduce.application.classpath` when a job is submitted to Yarn. Users can override this behavior by setting `spark.yarn.populateHadoopClasspath` to `true`.
### Why are the changes needed?
Without this, Spark will populate the hadoop classpath from `yarn.application.classpath` and `mapreduce.application.classpath` even Spark distribution has built-in hadoop. This results jar conflict and many unexpected behaviors in runtime.

### What changes were proposed in this pull request?
At the moment, we switch to `https` urls for all the debian mirrors, but turns out some of the mirrors do not support. In this patch, we turn on https mode only for `deb.debian.org` mirror (as it supports SSL).

### What changes were proposed in this pull request?
This PR aims to activate `hadoop-2.7` profile by default in Kubernetes IT module.
### Why are the changes needed?
While SPARK-31881 added Hadoop 3.2 support, one default test dependency was moved to `hadoop-2.7` profile. It works when we give one of `hadoop-2.7` and `hadoop-3.2`, but it fails when we don't give any profile.

Improve the check logic on if all node managers are really being backlisted.
### Why are the changes needed?
I observed when the AM is out of sync with ResourceManager, or RM is having issue report back with current number of available NMs, something like below happens:
...
20/05/13 09:01:21 INFO RetryInvocationHandler: java.io.EOFException: End of File Exception between local host is: "client.zyx.com/x.x.x.124"; destination host is: "rm.zyx.com":8030; : java.io.EOFException; For more details see: http://wiki.apache.org/hadoop/EOFException, while invoking ApplicationMasterProtocolPBClientImpl.allocate over rm543. Trying to failover immediately.
...
20/05/13 09:01:28 WARN AMRMClientImpl: ApplicationMaster is out of sync with ResourceManager, hence resyncing.
...
then the spark job would suddenly run into AllNodeBlacklisted state:
...
20/05/13 09:01:31 INFO ApplicationMaster: Final app status: FAILED, exitCode: 11, (reason: Due to executor failures all available nodes are blacklisted)
...
but actually there's no black listed nodes in currentBlacklistedYarnNodes, and I do not see any blacklisting message from:
https://github.com/apache/spark/blob/master/resource-managers/yarn/src/main/scala/org/apache/spark/deploy/yarn/YarnAllocatorBlacklistTracker.scala#L119
We should only return isAllNodeBlacklisted =true when we see there are >0 numClusterNodes AND 'currentBlacklistedYarnNodes.size >= numClusterNodes'.

### What changes were proposed in this pull request?
This adds UI updates to support stage level scheduling and ResourceProfiles. 3 main things have been added. ResourceProfile id added to the Stage page, the Executors page now has an optional selectable column to show the ResourceProfile Id of each executor, and the Environment page now has a section with the ResourceProfile ids. Along with this the rest api for environment page was updated to include the Resource profile information.
I debating on splitting the resource profile information into its own page but I wasn't sure it called for a completely separate page. Open to peoples thoughts on this.
Screen shots:
### Why are the changes needed?
For user to be able to know what resource profile was used with which stage and executors. The resource profile information is also available so user debugging can see exactly what resources were requested with that profile.
### Does this PR introduce any user-facing change?
Yes, UI updates.

### What changes were proposed in this pull request?
This PR proposes to show the actual traceback when "handle large number of containers and tasks (SPARK-18750)" test fails in `LocalityPlacementStrategySuite`.
**It does not fully resolve the JIRA SPARK-31746 yet**. I tried to reproduce in my local by controlling the factors in the tests but I couldn't. I double checked the changes in SPARK-18750 are still valid.
### Why are the changes needed?
This test is flaky for an unknown reason (see https://amplab.cs.berkeley.edu/jenkins/job/SparkPullRequestBuilder/122768/testReport/org.apache.spark.deploy.yarn/LocalityPlacementStrategySuite/handle_large_number_of_containers_and_tasks__SPARK_18750_/):

### What changes were proposed in this pull request?
This PR aims to recover Hadoop-3.2 profile jobs on `master` branch by disabling a UT added by SPARK-31235 in Hadoop 3.2 temporarily. The target UT is not a flaky test. It always fail on Hadoop-3.2 profile currently although it works in Hadoop 2.7 profile. So, in this PR, we keep the test coverage in Hadoop 2.7 and ignore the test in Hadoop 3.2 temporarily to unblock the other PRs.
### Why are the changes needed?
SPARK-31235 added a test case which is breaking Hadoop 3.2 and there are two follow-up to fix it. Although two follow-ups can fix the UT in Hadoop 3.2 environment. The side-effect on Hadoop classes cause some random UT failures in the other suites.

### What changes were proposed in this pull request?
This patch re-obtain tokens at the start of AM for yarn cluster mode, if principal and keytab are available. It basically transfers the credentials from the original user, so this patch puts the new tokens into credentials from the original user via overwriting.
To obtain tokens from providers in user application, this patch leverages the user classloader as context classloader while initializing token manager in the startup of AM.
### Why are the changes needed?
Submitter will obtain delegation tokens for yarn-cluster mode, and add these credentials to the launch context. AM will be launched with these credentials, and AM and driver are able to leverage these tokens.
In Yarn cluster mode, driver is launched in AM, which in turn initializes token manager (while initializing SparkContext) and obtain delegation tokens (+ schedule to renew) if both principal and keytab are available.
That said, even we provide principal and keytab to run application with yarn-cluster mode, AM always starts with initial tokens from launch context until token manager runs and obtains delegation tokens.
So there's a "gap", and if user codes (driver) access to external system with delegation tokens (e.g. HDFS) before initializing SparkContext, it cannot leverage the tokens token manager will obtain. It will make the application fail if AM is killed "after" the initial tokens are expired and relaunched.
This is even a regression: see below codes in branch-2.4:
https://github.com/apache/spark/blob/branch-2.4/resource-managers/yarn/src/main/scala/org/apache/spark/deploy/yarn/ApplicationMaster.scalahttps://github.com/apache/spark/blob/branch-2.4/resource-managers/yarn/src/main/scala/org/apache/spark/deploy/yarn/security/AMCredentialRenewer.scala
In Spark 2.4.x, AM runs AMCredentialRenewer at initialization, and AMCredentialRenew obtains tokens and merge with credentials being provided with launch context of AM. So it guarantees new tokens in driver run.
### Does this PR introduce any user-facing change?
No.
### How was this patch tested?
Manually tested with specifically crafted application (simple reproducer) - https://github.com/HeartSaVioR/spark-delegation-token-experiment/blob/master/src/main/scala/net/heartsavior/spark/example/LongRunningAppWithHDFSConfig.scala
Before this patch, new AM attempt failed when I killed AM after the expiration of tokens. After this patch the new AM attempt runs fine.

### Why are the changes needed?
The current application defaults to the SPARK type.
In fact, different types of applications have different characteristics and are suitable for different scenarios.For example: SPAKR-SQL, SPARK-STREAMING.
I recommend distinguishing them by the parameter `spark.yarn.applicationType` so that we can more easily manage and maintain different types of applications.

.setApplicationType(YarnConfiguration.DEFAULT_APPLICATION_TYPE);
} else {
// APPLICATION_TYPE_LENGTH = 20

### What changes were proposed in this pull request?
We are adding a new Spark Yarn configuration, `spark.yarn.populateHadoopClasspath` to not populate Hadoop classpath from `yarn.application.classpath` and `mapreduce.application.classpath`.
### Why are the changes needed?
Spark Yarn client populates extra Hadoop classpath from `yarn.application.classpath` and `mapreduce.application.classpath` when a job is submitted to a Yarn Hadoop cluster.
However, for `with-hadoop` Spark build that embeds Hadoop runtime, it can cause jar conflicts because Spark distribution can contain different version of Hadoop jars.
One case we have is when a user uses an Apache Spark distribution with its-own embedded hadoop, and submits a job to Cloudera or Hortonworks Yarn clusters, because of two different incompatible Hadoop jars in the classpath, it runs into errors.
By not populating the Hadoop classpath from the clusters can address this issue.
### Does this PR introduce any user-facing change?
No.
### How was this patch tested?
An UT is added, but very hard to add a new integration test since this requires using different incompatible versions of Hadoop.
We also manually tested this PR, and we are able to submit a Spark job using Spark distribution built with Apache Hadoop 2.10 to CDH 5.6 without populating CDH classpath.

This issue mainly shows up when you enable dynamic allocation:
because there are many executor state changes (because of executors
being requested and starting to run, and later stopped), the lifecycle
manager class could end up logging information about the same executor
multiple times, since the different events would cause the same
executor update to be present in multiple pod snapshots. On top of that,
it could end up making multiple redundant calls into the API server
for the same pod.
Another issue was when the config was set to not delete executor
pods; with dynamic allocation, that means pods keep accumulating
in the API server, and every time the full sync is done by the
polling source, all executors, even the finished ones that Spark
technically does not care about anymore, would be processed.
The change modifies the lifecycle monitor so that it:
- logs executor updates a single time, even if it shows up in
multiple snapshots, by checking whether the state change
happened before.
- marks finished-but-not-deleted-in-k8s executors with a label
so that they can be easily filtered out.
This reduces the amount of logging done by the lifecycle manager,
which is a minor thing in general since the logs are at debug level.
But it also reduces the amount of data that needs to be fetched
from the API server under certain configurations, and overall
reduces interaction with the API server when dynamic allocation is on.
There's also a change in the snapshot store to ensure that the
same subscriber is not called concurrently. That is kind of a bug,
since it means subscribers could be processing snapshots out of order,
or even that they could block multiple threads (e.g. the allocator
callback was synchronized). I actually ran into the "concurrent calls"
situation in the lifecycle manager during testing, and while it did not
seem to cause problems, it did make for some head scratching while
looking at the logs. It seemed safer to fix that.
Unit tests were updated to check for the changes. Also tested in real
cluster with dynamic allocation on.

### What changes were proposed in this pull request?
This PR (SPARK-31394) aims to add a new feature that enables mounting of Kubernetes NFS volumes. Most of the codes are just slight modifications from the existing codes for EmptyDir/HostDir/PVC support.
### Why are the changes needed?
Kubernetes supports various kinds of volumes, but Spark for Kubernetes supports only EmptyDir/HostDir/PVC. By adding support for NFS, we can use Spark for Kubernetes with NFS storage.
In order to use NFS with the current Spark using PVC, the user needs to first create an empty new PVC with NFS. Kubernetes' NFS provisioner will create a new empty dir in NFS under some pre-configured dir for this PVC, for example, `/nfs/k8s/sjcho-my-notebook-pvc-dce84888-7a9d-11e6-b1ee-5254001e0c1b`. Then the user should add files to process in the newly created PVC using some file-copying job, and then run the desired Spark job using that populated PVC. And then to get the final results out, the user should run another file-copying job.
This in theory works, but for data analysis tasks, is quite cumbersome. With this change, one could simply use existing files in NFS, say `/nfs/home/sjcho/myfiles10.sstable` from the Spark job directly, and also write the results directly to some existing dir under NFS such as `/nfs/home/sjcho/output`.
This PR doesn't use any features other than the features already provided by Kubernetes itself, so there should be no compatibility issues (other than limited by k8s) between the wide variety of NFS choices. This PR merely enables an existing volume type `nfs` supported officially by Kubernetes, just like Spark is currently supporting `hostPath` and `persistentVolumeClaim` right now.
### Does this PR introduce any user-facing change?
Users can now mount NFS volumes by running commands like:
```
spark-submit \
--conf spark.kubernetes.driver.volumes.nfs.myshare.mount.path=/myshare \
--conf spark.kubernetes.driver.volumes.nfs.myshare.mount.readOnly=false \
--conf spark.kubernetes.driver.volumes.nfs.myshare.options.server=nfs.example.com \
--conf spark.kubernetes.driver.volumes.nfs.myshare.options.path=/storage/myshare \
...
```
### How was this patch tested?
Test cases were added just like the existing EmptyDir support.
The code were tested using minikube using the following script:
https://gist.github.com/w4-sjcho/4ba48f8c35a9685f5307fbd46b2c0656#file-run-test-sh
The script creates a new minikube cluster, launches an NFS server inside the cluster, copy `README.md` file to the NFS share, and run `JavaWordCount` example against the file located in NFS.

### What changes were proposed in this pull request?
[Delay scheduling](http://elmeleegy.com/khaled/papers/delay_scheduling.pdf) is an optimization that sacrifices fairness for data locality in order to improve cluster and workload throughput.
One useful definition of "delay" here is how much time has passed since the TaskSet was using its fair share of resources.
However it is impractical to calculate this delay, as it would require running simulations assuming no delay scheduling. Tasks would be run in different orders with different run times.
Currently the heuristic used to estimate this delay is the time since a task was last launched for a TaskSet. The problem is that it essentially does not account for resource utilization, potentially leaving the cluster heavily underutilized.
This PR modifies the heuristic in an attempt to move closer to the useful definition of delay above.
The newly proposed delay is the time since a TasksSet last launched a task **and** did not reject any resources due to delay scheduling when offered its "fair share".
See the last comments of #26696 for more discussion.
### Why are the changes needed?
cluster can become heavily underutilized as described in [SPARK-18886](https://issues.apache.org/jira/browse/SPARK-18886?jql=project%20%3D%20SPARK%20AND%20text%20~%20delay)

### What changes were proposed in this pull request?
This is the core scheduler changes to support Stage level scheduling.
The main changes here include modification to the DAGScheduler to look at the ResourceProfiles associated with an RDD and have those applied inside the scheduler.
Currently if multiple RDD's in a stage have conflicting ResourceProfiles we throw an error. logic to allow this will happen in SPARK-29153. I added the interfaces to RDD to add and get the REsourceProfile so that I could add unit tests for the scheduler. These are marked as private for now until we finish the feature and will be exposed in SPARK-29150. If you think this is confusing I can remove those and remove the tests and add them back later.
I modified the task scheduler to make sure to only schedule on executor that exactly match the resource profile. It will then check those executors to make sure the current resources meet the task needs before assigning it. In here I changed the way we do the custom resource assignment.
Other changes here include having the cpus per task passed around so that we can properly account for them. Previously we just used the one global config, but now it can change based on the ResourceProfile.
I removed the exceptions that require the cores to be the limiting resource. With this change all the places I found that used executor cores /task cpus as slots has been updated to use the ResourceProfile logic and look to see what resource is limiting.
### Why are the changes needed?
Stage level sheduling feature
### Does this PR introduce any user-facing change?
No
### How was this patch tested?
unit tests and lots of manual testing

### What changes were proposed in this pull request?
This PR (SPARK-31244) replaces `Ceph` with `Minio` in K8S `DepsTestSuite`.
### Why are the changes needed?
Currently, `DepsTestsSuite` is using `ceph` for S3 storage. However, the used version and all new releases are broken on new `minikube` releases. We had better use more robust and small one.
```
$ minikube version
minikube version: v1.8.2
$ minikube -p minikube docker-env | source
$ docker run -it --rm -e NETWORK_AUTO_DETECT=4 -e RGW_FRONTEND_PORT=8000 -e SREE_PORT=5001 -e CEPH_DEMO_UID=nano -e CEPH_DAEMON=demo ceph/daemon:v4.0.3-stable-4.0-nautilus-centos-7-x86_64 /bin/sh
2020-03-25 04:26:21 /opt/ceph-container/bin/entrypoint.sh: ERROR- it looks like we have not been able to discover the network settings
$ docker run -it --rm -e NETWORK_AUTO_DETECT=4 -e RGW_FRONTEND_PORT=8000 -e SREE_PORT=5001 -e CEPH_DEMO_UID=nano -e CEPH_DAEMON=demo ceph/daemon:v4.0.11-stable-4.0-nautilus-centos-7 /bin/sh
2020-03-25 04:20:30 /opt/ceph-container/bin/entrypoint.sh: ERROR- it looks like we have not been able to discover the network settings
```
Also, the image size is unnecessarily big (almost `1GB`) and growing while `minio` is `55.8MB` with the same features.
```
$ docker images | grep ceph
ceph/daemon v4.0.3-stable-4.0-nautilus-centos-7-x86_64 a6a05ccdf924 6 months ago 852MB
ceph/daemon v4.0.11-stable-4.0-nautilus-centos-7 87f695550d8e 12 hours ago 901MB
$ docker images | grep minio
minio/minio latest 95c226551ea6 5 days ago 55.8MB
```
### Does this PR introduce any user-facing change?
No. (This is a test case change)
### How was this patch tested?
Pass the existing Jenkins K8s integration test job and test with the latest minikube.
```
$ minikube version
minikube version: v1.8.2
$ kubectl version --short
Client Version: v1.17.4
Server Version: v1.17.4
$ NO_MANUAL=1 ./dev/make-distribution.sh --r --pip --tgz -Pkubernetes
$ resource-managers/kubernetes/integration-tests/dev/dev-run-integration-tests.sh --spark-tgz $PWD/spark-*.tgz
...

### What changes were proposed in this pull request?
This is a follow up for SPARK-30715 . Kubernetes client version in sync in integration-tests and kubernetes/core
### Why are the changes needed?
More than once, the kubernetes client version has gone out of sync between integration tests and kubernetes/core. So brought them up in sync again and added a comment to save us from future need of this additional followup.
### Does this PR introduce any user-facing change?
No
### How was this patch tested?
Manually.

### What changes were proposed in this pull request?
Change what we consider a deleted pod to not include "Terminating"
### Why are the changes needed?
If we get a new snapshot while a pod is in the process of being cleaned up we shouldn't delete the executor until it is fully terminated.
### Does this PR introduce any user-facing change?
No
### How was this patch tested?
This should be covered by the decommissioning tests in that they currently are flaky because we sometimes delete the executor instead of allowing it to decommission all the way.
I also ran this in a loop locally ~80 times with the only failures being the PV suite because of unrelated minikube mount issues.

### What changes were proposed in this pull request?
This PR adds the proxy user on the spark-submit command to the childArgs, so the proxy user can be retrieved and used in the KubernetesAplication to add the proxy user in the driver container args
### Why are the changes needed?
The proxy user when used on the spark submit doesn't work on the Kubernetes environment since it doesn't add the `--proxy-user` argument on the driver container and when I added it manually to the Pod definition it worked just fine.
### Does this PR introduce any user-facing change?
No.
### How was this patch tested?
Tests were added

### 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.
Closes#27370 from clarkead/bootstrap4-core-upgrade.
