There were some test failures caused by the background retention lease sync running on a relocated

This commit deprecates versions of Java prior to Java 11. This commit
will cause a warning to be printed to standard error when any command
line tool is invoked, or when Elasticsearch is started. Additionally, we
log a deprecation message when Elasticsearch is started.
We recently introduced the option to minimize network roundtrips when
executing cross-cluster search requests. All the changes made around
that are separately unit tested, and there are some yaml tests that
exercise the new code-path which involves multiple coordination steps.
This commit adds new integration tests that compare the output given by
CCS when running the same queries using the two different execution
modes available.

On windows, JAVA_HOME is currently resolved when the windows service is started. However, this is contrary to what our documentation states. This commit moves resolution to service install. This has the side effect of making java existence checking optional in elasticsearch-env.bat, since the rest of the service commands do not require java.

With this change, we will dump the recovery state if we fail to get doc
count for a given index with a preference in rolling upgrade tests. We
should have more information to look into why the provided preference is
not valid. I also unmuted `testRelocationWithConcurrentIndexing` in this
change.

When a node is repurposed to master/no-data or no-master/no-data, v7.x
will not start (see #37748 and #37347). The `elasticsearch repurpose`
tool can fix this by cleaning up the problematic data.
This commit adds cd $ES_HOME to elasticsearch-env and removes it from
elasticsearch. This way, both elasticsearch and elasticsearch-cli are
executed with the working directory set to $ES_HOME. The need for the
fix arose from the following bug:
1. Explicitly set path.data to relative to ES_HOME path in
elasticsearch.yml.
2. Run elasticsearch from any directory. Elasticsearch is able to
correctly start.
3. Stop elasticsearch.
4. Run elasticsearch-node unsafe-bootstrap, not from ES_HOME directory.
It will fail with an exception.

with fixes by #40083 and #40118)
This commit removes the cluster state size field from the cluster state
response, and drops the backwards compatibility layer added in 6.7.0 to
continue to support this field. As calculation of this field was
expensive and had dubious value, we have elected to remove this field.
This commit adds a variant for every official distribution that omits
the bundled jdk. The "no-jdk" naming is conveyed through the package
classifier, alongside the platform. Package tests are also added for
each new distribution.
Computing the compressed size of the cluster state on every invocation
of cluster:monitor/state action is expensive, and the value of this
field is dubious anyway. Therefore we want to remove computing this
field. As a first step, we stop computing and return this field by
default. To avoid breaking users, we will give them a system property to
use to tide them over until the next major release when we will actually
remove this field. This comes with a deprecation warning too, and the
backport to the appropriate minor will also include a note in the
migration guide. There will be a follow-up to remove this field in the
next major version.
Executors of type fixed_auto_queue_size (i.e. search / search_throttled) wrap runnables into
TimedRunnable, which is an AbstractRunnable. This is dangerous as it might silently swallow
exceptions, and possibly miss calling a response listener. While this has not triggered any failures in
the tests I have run so far, it might help uncover future problems.
Follow-up to #36137
* Bundle java in distributions
Setting up a jdk is currently a required external step when installing
elasticsearch. This is particularly problematic for the rpm/deb packages
as installing a jdk in the same package installation command does not
guarantee any order, so must be done in separate steps. Additionally,
JAVA_HOME must be set and often causes problems in selecting a correct
jdk when, for example, the system java is an older unsupported version.
This commit bundles platform specific openjdks into each distribution.
In addition to eliminating the issues above, it also presents future
possible improvements like using jlink to build jdk images only
containing modules that elasticsearch uses.

* Back port build changes from #39102
This back-ports how versions are determined and bwc test are set up from

easier/possible to backmerge future buld changes.
It's expected that the tets are lacking many of the required fixes in
this version to enable them.
Backport support for replicating closed indices (#39499)
Before this change, closed indexes were simply not replicated. It was therefore
possible to close an index and then decommission a data node without knowing
that this data node contained shards of the closed index, potentially leading to
data loss. Shards of closed indices were not completely taken into account when
balancing the shards within the cluster, or automatically replicated through shard
copies, and they were not easily movable from node A to node B using APIs like
Cluster Reroute without being fully reopened and closed again.
This commit changes the logic executed when closing an index, so that its shards
are not just removed and forgotten but are instead reinitialized and reallocated on
data nodes using an engine implementation which does not allow searching or
indexing, which has a low memory overhead (compared with searchable/indexable
opened shards) and which allows shards to be recovered from peer or promoted
as primaries when needed.
This new closing logic is built on top of the new Close Index API introduced in
6.7.0 (#37359). Some pre-closing sanity checks are executed on the shards before
closing them, and closing an index on a 8.0 cluster will reinitialize the index shards
and therefore impact the cluster health.
Some APIs have been adapted to make them work with closed indices:
- Cluster Health API
- Cluster Reroute API
- Cluster Allocation Explain API
- Recovery API
- Cat Indices
- Cat Shards
- Cat Health
- Cat Recovery

Finding java on the path is sometimes confusing for users and
unexpected, as well as leading to a different java being used than a
user expects. This commit adds warning messages when starting
elasticsearch (or any tools like the plugin cli) and using java found
on the PATH instead of via JAVA_HOME.
This test failed on 7.1 when running full cluster restart tests against pre-7.0
clusters (e.g. 6.6 clusters). The fixes the expected type in the
templates after the cluster restart.
Instead of using `WarningsHandler.PERMISSIVE`, we only match warnings
that are due to types removal.
This PR also renames `allowTypeRemovalWarnings` to `allowTypesRemovalWarnings`.

We have had various reports of problems caused by the maxRetryTimeout
setting in the low-level REST client. Such setting was initially added
in the attempts to not have requests go through retries if the request
already took longer than the provided timeout.
The implementation was problematic though as such timeout would also
expire in the first request attempt (see #31834), would leave the
request executing after expiration causing memory leaks (see #33342),
and would not take into account the http client internal queuing (see #25951).
Given all these issues, it seems that this custom timeout mechanism
gives little benefits while causing a lot of harm. We should rather rely
on connect and socket timeout exposed by the underlying http client
and accept that a request can overall take longer than the configured
timeout, which is the case even with a single retry anyways.
This commit removes the `maxRetryTimeout` setting and all of its usages.
Instead of logging warnings we now rethrow exceptions thrown inside
scheduled/submitted tasks. This will still log them as warnings in
production but has the added benefit that if they are thrown during
unit/integration test runs, the test will be flagged as an error.
This is a continuation of #38014

Relax test warning message checking to pre-empt PR 38022 landing in 6.7 with new warning messages.
The relaxed test now just assumes any warning message starting with “[types removal]” is tolerated rather than the precise phrasing used in the 6.7 branch.
We now throw a WarningFailureException instead of ResponseException if
there's any warning in a response. This change leads to the failures of
testSnapshotRestore in the BWC builds for the last two days.
Relates #37247
This PR removes the temporary change we made to the yml test harness in #37285
to automatically set `include_type_name` to `true` in index creation requests
if it's not already specified. This is possible now that the vast majority of
index creation requests were updated to be typeless in #37611. A few additional
tests also needed updating here.
Additionally, this PR updates the test harness to set `include_type_name` to
`false` in index creation requests when communicating with 6.x nodes. This
mirrors the logic added in #37611 to allow for typeless document write requests
in test set-up code. With this update in place, we can remove many references
to `include_type_name: false` from the yml tests.
With #37000 we made sure that fnial reduction is automatically disabled
whenever a localClusterAlias is provided with a SearchRequest.
While working on #37838, we found a scenario where we do need to set a
localClusterAlias yet we would like to perform a final reduction in the
remote cluster: when searching on a single remote cluster.
Relates to #32125
This commit adds support for a separate finalReduce flag to
SearchRequest and makes use of it in TransportSearchAction in case we
are searching against a single remote cluster.
This also makes sure that num_reduce_phases is correct when searching
against a single remote cluster: it makes little sense to return
`num_reduce_phases` set to `2`, which looks especially weird in case
the search was performed against a single remote shard. We should
perform one reduction phase only in this case and `num_reduce_phases`
should reflect that.

This test failed once because the index wasn't fully ready
(ie, engine opened). This commit changes the test so that
it waits for the index to be green before checking the history
UUID.
Closes#34452
Scheduler.schedule(...) would previously assume that caller handles
exception by calling get() on the returned ScheduledFuture.
schedule() now returns a ScheduledCancellable that no longer gives
access to the exception. Instead, any exception thrown out of a
scheduled Runnable is logged as a warning.
This is a continuation of #28667, #36137 and also fixes#37708.
With #37566 we have introduced the ability to merge multiple search responses into one. That makes it possible to expose a new way of executing cross-cluster search requests, that makes CCS much faster whenever there is network latency between the CCS coordinating node and the remote clusters. The coordinating node can now send a single search request to each remote cluster, which gets reduced by each one of them. from + size results are requested to each cluster, and the reduce phase in each cluster is non final (meaning that buckets are not pruned and pipeline aggs are not executed). The CCS coordinating node performs an additional, final reduction, which produces one search response out of the multiple responses received from the different clusters.
This new execution path will be activated by default for any CCS request unless a scroll is provided or inner hits are requested as part of field collapsing. The search API accepts now a new parameter called ccs_minimize_roundtrips that allows to opt-out of the default behaviour.

Today we pass `discovery.zen.minimum_master_nodes` to nodes started up in
tests, but for 7.x nodes this setting is not required as it has no effect.
This commit removes this setting so that nodes are started with more realistic
configurations, and deprecates it.
Doc-value fields now return a value that is based on the mappings rather than
the script implementation by default.
This deprecates the special `use_field_mapping` docvalue format which was added
in #29639 only to ease the transition to 7.x and it is not necessary anymore in
7.0.
This commit restores a noop version of the AllFieldMapper that is instanciated only
for indices created in 6x. We need this metadata field mapper to be present in this version
in order to allow the upgrade of indices that explicitly disable _all (enabled: false).
The mapping of these indices contains a reference to the _all field that we cannot remove
in 7 so we'll need to keep this metadata mapper in 7x. Since indices created in 6x will not
be compatible with 8, we'll remove this noop mapper in the next major version.
Closes#37429
The certgen, certutil and saml-metadata tools did not correctly return
their exit code to the calling shell.
These commands now explicitly exit with the code that was returned

HLRC changes:
GetIndexTemplateRequest has a new client-side class which is a copy of server's GetIndexTemplateResponse but modified to be typeless.
