conform with the requirements of the writeBlob method by
throwing a FileAlreadyExistsException if attempting to write
to a blob that already exists. This change means implementations
of BlobContainer should never overwrite blobs - to overwrite a
blob, it must first be deleted and then can be written again.

* Allow to run client benchmark as an uberjar
* Busy wait to avoid accidental skew on low target throughput rates
* Trigger and wait for full GC to happen between trials
* Add missing SuppressForbidden to allow System.gc in client benchmark
With this commit we add documentation and additional checks to
enforce the cancellation policy of CancellableThreads (which is
disallow `Thread#interrupt()` on any of the threads managed by
it).
This fixes a bug in the RunningStats class for the matrix stats aggregation module. doc counts were not being searlized which means they were only computed the first time the aggregation was computed. This was causing incorrect results when the aggregation was pulled from cache.
If the uuidBytes and ref are converted to utf8, it's possible they can
trip an assertion related to valid UTF-8/UTF-16 ranges, so display them
as hex, not as strings.
method to determine if a write consistency check should be performed
before proceeding with the action. This commit removes this method from
the transport replication actions in favor of setting the ActiveShardCount
on the request, with setting the value to ActiveShardCount.NONE if the
transport action's checkWriteConsistency() method returned false.
After #13834 many tests that used Groovy scripts (for good or bad reason) in their tests have been moved in the lang-groovy module and the issue #13837 has been created to track these messy tests in order to clean them up.
The work started with #19280, #19302 and #19336 and this PR moves the remaining messy tests back in core, removes the dependency on Groovy, changes the scripts in order to use the mocked script engine, and change the tests to integration tests.
It also moves IndexLookupIT test back (even if it has good chance to be removed soon) and fixes its tests.
It also changes AbstractQueryTestCase to use custom script plugins in tests.

* Rename operation to result and reworking responses
* Rename DocWriteResponse.Operation enum to DocWriteResponse.Result
These are just easier to interpret names.
Closes#19664
During our master elections, nodes "vote" for a master being issuing a join request to it. Since this is done in an async fashion, joins may arrive before the master itself has realized it had won the election. Therefore we start accumulating node joins on every node at election start (we don't know the result yet). When the election finish nodes that did not become the master (i.e., joined another node which won the election) need to potentially process and fail any incoming join request they may have received during the election. This is currently achieved by always issuing a cluster state update task that is doomed to fail, even if no pending joins are actually there. That aspect results in confusing (debug) log messages, making it seems like something is wrong. For example (note that `NotMasterException`)

This commit cleans up the logic a bit to only use failure where there are actual joins that are failed. The result is cleaner logs as well:

Before this commit when an index pattern is used to filter the cluster state, only indices metadata are populated and routing table is just empty. This commit aligns the behavior of the filtering of cluster state's routing table with the filtering of cluster state's metadata so that coherent data are returned for both routing table & metadata when index pattern is requested.
In an effort to reduce the number of tiny packages we have in the
code base this moves all the files that were in subdirectories of
`org.elasticsearch.rest.action.admin.cluster` into
`org.elasticsearch.rest.action.admin.cluster`.
Also fixes line length in these packages.
`_reindex` only needs the `_version` if the `dest` has
`"version_type": "external"`. So it shouldn't ask for it unless it does.
`_update_by_query` and `_delete_by_query` always need the `_version`.
Closes#19135
This is cleanup work from #19566, where @nik9000 suggested trying to nuke the isCreated and isFound methods. I've combined nuking the two methods with removing UpdateHelper.Operation in favor of DocWriteResponse.Operation here.
Closes#19631.
Reindex from remote uses the Elasticsearch client which uses apache
httpasyncclient which spins up 5 thread by default, 1 as a dispatcher
and 4 more to handle IO. This changes Reindex's usage so it only spins
up two thread - 1 dispatcher and one to handle io. It also renames the
threads to "es-client-$taskid-$thread_number". That way if we see any
thread sticking around we can trace it back to the task.
