The test check that the number of outgoing/incoming recoveries of a shard is 0 after recoveries were done. Sadly that is not guaranteed by the current recovery logic as we decrement the counters only when all references to the relevant RecoveryTarget object have been released. This may happen in an async fashion to the recovery completion which causes the test to fail. I looked at options to change the recovery logic to have the recovery counters decrease before the recovery is done *under normally circumstances* but I don't see a clean way to do it. Since it won't give hard guarantees anyway I opted to add assertBusy to the test

This commit adds a deprecation warning if `_index` is used in scripts.
It is emitted each time a script is invoked, but not per document. There
is no test because constructing a LeafIndexLookup is quite difficult,
but the deprecation warning does show up in IndexLookupIT, there is just
no way to assert warnings in integ tests.

Today we assert hart if failure listeners are invoked more than once. Yet, this
can happen if we cancel the execution since the caller and the handler will get
the exception on the cancelable threads and will notify the listener concurrently
if timinig allows. This commit relaxes the assertion towards handling multiple
invocations with `ExecutionCancelledException`

Template script engines (mustache, the only one) currently return a
BytesReference that users must know is utf8 encoded. This commit
modifies all callers and mustache to have the template engine return
String. This is much simpler, and does not require decoding in order to
use (for example, in ingest).
We had a hack in setting up permissions for tests to support testing
the lang-python plugin. We also had a hack to prevent Log4j from
loading a shaded version of Jansi provided by Jython. This plugin has
been removed so these hacks are no longer necessary.

When retrieving documents to extract terms from as part of a more like this query, the _routing value can be set, yet it gets lost. That leads to not being able to retrieve the documents, hence more_like_this used to return no matches all the time.
Closes#23699
We generally accept string values when a boolean is expected. We've been doing that in our parsing code, but we missed that bit when moving parsing code to ObjectParser, which throws an error instead. This commit makes ObjectParser parse also string values into booleans. It throws an error in case the value is not `true` or `false`.
Closes#21802
The rendering methods in String and Long Significant String aggregations
and buckets are very similar. They can be factored out in the
InternalSignificantTerms class an InternalMappedSignificantTerms class.
This commit changes SignificantTerms.Bucket so that it is not an
abstract class anymore but an interface. It will be easier for the Java
High Level Rest Client to provide its own implementation of
SignificantTerms and SignificantTerms.Bucket. Also, it is now more
coherent with the others aggregations.
The disruption tests sit in a single test suite which causes these tests
to be single-threaded. We can split this test suite into multiple suites
(logically, of course) enabling them to be run in parallel reducing the
total run time of all integration tests in core. This commit splits the
discovery with service disruptions test suite into three suites
- master disruptions
- discovery disruptions
- cluster disruptions
The last one could probably be better named, it is meant to represent
performing actions in the cluster (indexing, failing a shard, etc.)
while a disruption is taking place.

This commit removes the deprecated support for .yaml and .json files. If
the files still exist, the node will fail to start, indicating the file
must be converted or renamed.

Our strong recommendation is disabling swap over any other alternative
to avoid the JVM from landing on disk. This commit clarifies the docs in
this regard.
Netty removed a logging guarded we added to prevent a scary logging
message. We added a hack to work around this. They've added the guard
back, so we can remove the hack now.
With the current implementation, SniffNodesSampler might close the
current connection right after a request is sent but before the response
is correctly handled. This causes to timeouts in the transport client
when the sniffing is activated.

When constructing an array list, if we know the size of the list in
advance (because we are adding objects to it derived from another list),
we should size the array list to the appropriate capacity in advance (to
avoid resizing allocations). This commit does this in various places.

* Add parent-join module
This change adds a new module named `parent-join`.
The goal of this module is to provide a replacement for the `_parent` field but as a first step this change only moves the `has_child`, `has_parent` queries and the `children` aggregation to this module.
These queries and aggregations are no longer in core but they are deployed by default as a module.

Today we prune transport handlers in TransportService when a node is disconnected.
This can cause connections to starve in the TransportService if the connection is
opened as a short living connection ie. without sharing the connection to a node
via registering in the transport itself. This change now moves to pruning based
on the connections cache key to ensure we notify handlers as soon as the connection
is closed for all connections not just for registered connections.

In windows we can't reliable git the pid so we skip the
reindex-from-remote tests from old versions of elasticsearch. This
is OK because we aren't really testing windows here anyway. It isn't
great, but should be safe.
If the request asks for the `_source` stored field then don't
duplicate it when forcing the `_source` parameter to onto the
request for reindex-from-remote from versions before 1.0.
