This commit removes the environment variable ES_JVM_OPTIONS that allows
the jvm.options file to sit separately from the rest of the config
directory. Instead, we use the CONF_DIR environment variable for custom
configuration location just as we do for the other configuration files.

This commit reverts a rename of the systemd packaging tests. The rename
was done locally to speed up iteration of testing some changes against
systemd but was not reverted before pushing. This commit reverts this
change.
On Debian-based systems the install scripts are run with set -e meaning
that if there is an error in executing one of these scripts then the
script fails. If systemd-sysctl is masked then trying to restart the
systemd-sysctl service to pick up the changes to vm.max_map_count will
fail leading to the post-install script failing. Instead, we should
account for the possbility of failure here by not letting the command to
restart this service exit with non-zero status code. This commit does
this, and adds a test for this situation.

We lost the cluster alias due to some special caseing in inner hits
and due to the fact that we didn't pass on the alias to the shard request.
This change ensures that we have the cluster alias present on the shard to
ensure all SearchShardTarget reads preserve the alias.

This commit enables the console appender for the settings deprecation
logger used in the deprecated settings logging test. This output will be
useful if this test fails again (it failed once mysteriously).

In the past global checkpoint syncing was done in the background based an interval set by an index setting. In order to set that setting something reasonable for a test, the master needed to know about the setting. Therefore the test didn't check global checkpoints if the master was old. These days the global checkpoint sync is inlined with indexing operations and that restriction is not needed.
In the rolling upgrade tests, there is a test to create an index with
replica shards and ensure that in the mixed cluster environment, the
cluster health is green before any other tests are executed. However,
there were two problems with this. First, if the replica shard was
residing on the restarted node, then delayed allocation will kick in and
cause the cluster health request to timeout after 1m. The fix to this
was to drastically lower the delayed allocation setting. Second, if the
primary exists on the higher version node, then the replica cannot be
assigned to the lower version node because recovery cannot happen from
lower lucene versions. The fix here was to wait for the cluster health
to be yellow instead of green in the mixed cluster environment. In the
fully upgraded cluster, the cluster health check waits for a green
cluster as before.
Closes#25185
In 6.x we prevent multiple types and default to `index.mapping.single_type: false`
This change removes the registered setting and ensures that it's preserved for
5.x indices.

This commit adds an LRU set to used to determine if a keyed deprecation
message should be written to the deprecation logs, or only added to the
response headers on the thread context.

Currently QueryParseContext is only a thin wrapper around an XContentParser that
adds little functionality of its own. I provides helpers for long deprecated
field names which can be removed and two helper methods that can be made static
and moved to other classes. This is a first step in helping to remove
QueryParseContext entirely.
When a setting is deprecated, if that setting is used repeatedly we
currently emit a deprecation warning every time the setting is used. In
cases like hitting settings endpoints over and over against a node with
a lot of deprecated settings, this can lead to excessive deprecation
warnings which can crush a node. This commit ensures that a given
setting only sees deprecation logging at most once.

This commit changes how we determine if there were any remote indices that a search should have
been executed against. Previously, we used the list of remote shard iterators but if the remote
index pattern resolved to no indices there would be no remote shard iterators even though the
request specified remote indices. The map of remote cluster names to the original indices is used
instead so that we can determine if there were remote indices even when there are no remote shard
iterators.
Closes#25426
This commit removes the default path settings for data and logs. With
this change, we now ship the packages with these settings set in the
elasticsearch.yml configuration file rather than going through the
default.path.data and default.path.logs dance that we went through in
the past.

This commit removes path.conf as a valid setting and replaces it with a
command-line flag for specifying a non-default path for configuration.

* Remove the setting from the yml tests and replace with tests using
`join` field. We can't use the setting in yml tests without lots of
backflips but we have `ReindexParentChildTests` for the coverage.
There weren't tests for `join` field with reindex before this. Adding
these tests discovered #25363.
* Remove the setting from `ReindexParentChildTests` and replace with
`index.version.created=V_5_6_0`. This test can be entirely removed
when legacy parent/child support is dropped from core.
* Port the yml tests that set _parent into integ tests so they
can set the index created version. These tests can be removed
when we drop support for _parent in core.
* Port a delete-by-query test for filtering based on type to an
`ESIntegTestCase` so it can use `index.version.created=5.6.0` to
setup documents of multiple types. This whole feature can be dropped
when we no longer support multiple types per index.

Ports all of RepositoryUpgradabilityIT to qa:full-cluster-restart and ports as much of RestoreBackwardsCompatIT as possible into qa:full-cluster-restart.
This commit adds a gradle project, set inside the root build.gradle,
which controls all our bwc tests. This allows for seamless (ie no errant
CI failures) backporting of behavior.
In #25201, a setting was added to allow setting the retry timeout for the rest client under the
impression that this would allow requests to go longer than 30s. However, there is also a socket
timeout that needs to be set to greater than 30s, which this change adds a setting for.
This commit adds a setting to change the request timeout for the rest client. This is useful as the
default timeout is 30s, which is also the same default for calls like cluster health. If both are
the same then the response from the cluster health api will not be received as the client usually
times out first making test failures harder to debug.

Duplicate data paths already fail to work because we would attempt to
take out a node lock on the directory a second time which will fail
after the first lock attempt succeeds. However, how this failure
manifests is not apparent at all and is quite difficult to
debug. Instead, we should explicitly reject duplicate data paths to make
the failure cause more obvious.
Relates #25178
We have a custom logger implementation known as a prefix logger that is
used to write every message by the logger with a given prefix. This is
useful for node-level, index-level, and shard-level messages where we
want to log the node name, index name, and shard ID, respectively, if
possible. The mechanism that we employ is that of a marker. Log4j has a
built-in facility for managing these markers, but its effectively a
memory leak because these markers are held in a map and can never be
released. This is problematic for us since indices and shards do not
necessarily have infinite life spans and so on a node where there are
many indices being creted and destroyed, this infinite lifespan can be a
problem indeed. To solve this, we use our own cache of markers. This is
necessary to prevent too many instances of the marker for the same
prefix from being created (just think of all the shard-level components
that exist in the system), and to workaround the effective leak in
Log4j. These markers are stored as weak references in a weak hash
map. It is these weak references that are unneeded. When a key is
removed from a weak hash map, the corresponding entry is placed on a
reference queue that is eventually cleared. This commit simplifies
prefix logger by removing this unnecessary weak reference wrapper.

This commit adds back "id" as the key within a script to specify a
stored script (which with file scripts now gone is no longer ambiguous).
It also adds "source" as a replacement for "code". This is in an attempt
to normalize how scripts are specified across both put stored scripts and script usages, including search template requests. This also deprecates the old inline/stored keys.
This adds an option to `ClusterConfiguration` to preserve the
`shared` directory when starting up a new cluster and switches
the `qa:full-cluster-restart` tests to use it rather than
disable the clean shared task.
