## What changes were proposed in this pull request? - A separate subsection for Aggregations under “Getting Started” in the Spark SQL programming guide. It mentions which aggregate functions are predefined and how users can create their own. - Examples of using the `UserDefinedAggregateFunction` abstract class for untyped aggregations in Java and Scala. - Examples of using the `Aggregator` abstract class for type-safe aggregations in Java and Scala. - Python is not covered. - The PR might not resolve the ticket since I do not know what exactly was planned by the author. In total, there are four new standalone examples that can be executed via `spark-submit` or `run-example`. The updated Spark SQL programming guide references to these examples and does not contain hard-coded snippets. ## How was this patch tested? The patch was tested locally by building the docs. The examples were run as well.  Author: aokolnychyi <okolnychyyanton@gmail.com> Closes #16329 from aokolnychyi/SPARK-16046. (cherry picked from commit 3fdce814) Signed-off-by:

Current HistoryServer's ACLs is derived from application event-log, which means the newly changed ACLs cannot be applied to the old data, this will become a problem where newly added admin cannot access the old application history UI, only the new application can be affected. So here propose to add admin ACLs for history server, any configured user/group could have the view access to all the applications, while the view ACLs derived from application run-time still take effect. ## How was this patch tested?

## What changes were proposed in this pull request? Spark's current task cancellation / task killing mechanism is "best effort" because some tasks may not be interruptible or may not respond to their "killed" flags being set. If a significant fraction of a cluster's task slots are occupied by tasks that have been marked as killed but remain running then this can lead to a situation where new jobs and tasks are starved of resources that are being used by these zombie tasks. This patch aims to address this problem by adding a "task reaper" mechanism to executors. At a high-level, task killing now launches a new thread which attempts to kill the task and then watches the task and periodically checks whether it has been killed. The TaskReaper will periodically re-attempt to call `TaskRunner.kill()` and will log warnings if the task keeps running. I modified TaskRunner to rename its thread at the start of the task, allowing TaskReaper to take a thread dump and filter it in order to log stacktraces from the exact task thread that we are waiting to finish. If the task has not stopped after a configurable timeout then the TaskReaper will throw an exception to trigger executor JVM death, thereby forcibly freeing any resources consumed by the zombie tasks. This feature is flagged off by default and is controlled by four new configurations under the `spark.task.reaper.*` namespace. See the updated `configuration.md` doc for details. ## How was this patch tested? Tested via a new test case in `JobCancellationSuite`, plus manual testing. Author: Josh Rosen <joshrosen@databricks.com> Closes #16189 from JoshRosen/cancellation.

Note: MLlib Scala/Java/Python examples will be consistent, however, SparkR examples may different from them, since R users may use the algorithms in a different way, for example, using R ```formula``` to specify ```featuresCol``` and ```labelCol```. ## How was this patch tested?

## What changes were proposed in this pull request? If SparkR is running as a package and it has previously downloaded Spark Jar it should be able to run as before without having to set SPARK_HOME. Basically with this bug the auto install Spark will only work in the first session. This seems to be a regression on the earlier behavior. Fix is to always try to install or check for the cached Spark if running in an interactive session. As discussed before, we should probably only install Spark iff running in an interactive session (R shell, RStudio etc) ## How was this patch tested?
