This commit adds a special run.datadir system property that may be
passed to `./gradlew run` which sets the root data directory used by the
task. While normally overriding the data path is not allowed for test
clusters, it is useful when experimenting with the run task.

Avoid backwards incompatible changes for 8.x and 7.6 by removing type
restriction on compile and Factory. Factories may optionally implement
ScriptFactory. If so, then they can indicate determinism and thus
cacheability.

Converts the main README file to asciidoc.
Also includes the following changes:
* Mentioning Slack instead of IRC
* Removed mentioning of native java API, HTTP should be used
* Removed java as a installed requirement
When a third party test failed, it potentially left some snapshots
in the repository. In case of tests running against an external
service like Azure, the remaining snapshots can fail the future
test executions are they are not supposed to exist.
Similarly to what has been done for S3 and GCS, this commit
cleans up remaining snapshots before the test execution.
Closes#50304
We randomly generate intervals sources to test serialization and query generation
in IntervalQueryBuilderTests. However, rarely we can generate a query that has
too many nested disjunctions, resulting in query rewrites running afoul of the maximum
boolean clause limit.
This commit reduces the maximum depth of the randomly generated intervals source
to make running into this limit much more unlikely.
* Extract IndexCreationTask execute into applyCreateIndexRequest
This is the first step in preparation for separating the index creation into a few
steps that only deal with the cluster state mutation and removing the IndexCreationTask
altogether.
* Split applyCreateIndexRequest
This breaks down the logic in applyCreateIndexRequest into multiple
steps that will hopefully make the service more readable and unit testable.
The service creation process now goes through a few well defined steps,
namely find the templates that possibly match the new index, parse the
requested and template matching mappings, process the index and template
matching settings, validate the wait for active shards request and
create the `IndexService`, update the mappings in the `MapperService` (which
is grouped together with creating the sort order for validation purposes),
validate the requested and templated matching aliases and finally update
the `ClusterState` to reflect the requested changes.
This also removes the `IndexCreationTask` as it was a shallow
indirection and migrates the tests from `IndexCreationTaskTests` to
`MetaDataCreateIndexServiceTests` (making them "real" unit tests
operating on the `ClusterState` rather than mocks).
* Add more unit tests.
* Add IT to verify we cleanup in case of failure

In order to ensure any persisted model state is searchable by the moment
the job reports itself as `stopped`, we need to refresh the state index
before completing.
This should fix the occasional failures we see in #50168 and #50313 where
the model state appears missing.

This fixes support for nested fields
We now support fully nested, fully collapsed, or a mix of both on inference docs.
ES mappings allow the `_source` to be any combination of nested objects + dot delimited fields.
So, we should do our best to find the best path down the Map for the desired field.
Cache results from queries that use scripts if they use only
deterministic API calls. Nondeterministic API calls are marked in the
whitelist with the `@nondeterministic` annotation. Examples are
`Math.random()` and `new Date()`.

The freeze index API docs state that frozen indices are blocked for
write operations.
While this implies frozen indices are read-only, it does not explicitly
use the term "read-only", which is found in other docs, such as the
force merge docs.
This adds the "ready-only" term to the freeze index API docs as well
as other clarification.
The `filter` rule is not allowed on the top-level of the query, so removing it
from the list of allowed rules. Where it can be nested inside other rules, those
rules already mention it.
Docker bypasses the Uncomplicated Firewall (UFW) on Linux by editing the `iptables` config directly, which leads to the exposure of port 9200, even if you blocked it via UFW.
This adds a warning along with work-arounds to the docs.

Our REST infrastructure will reject requests that have a body where the
body of the request is never consumed. This ensures that we reject
requests on endpoints that do not support having a body. This requires
cooperation from the REST handlers though, to actually consume the body,
otherwise the REST infrastructure will proceed with rejecting the
request. This commit addresses an issue in the has privileges API where
we would prematurely try to reject a request for not having a username,
before consuming the body. Since the body was not consumed, the REST
infrastructure would instead reject the request as a bad request.
This commit adds removal of unused data frame analytics state

Users often mistakenly map numeric IDs to numeric datatypes. However,
this is often slow for the `term` and other term-level queries.
The "Tune for search speed" docs includes advice for mapping numeric
IDs to `keyword` fields. However, this tip is not included in the
`numeric` or `keyword` field datatype doc pages.
This rewords the tip in the "Tune for search speed" docs, relocates it
to the `numeric` field docs, and reuses it using tagged regions.
We need to read in a loop here. A single read to a huge byte array will
only read 16k max with the S3 SDK so if the blob we're trying to fully
read is larger we close early and fail the size comparison.
Also, drain streams fully when checking existence to avoid S3 SDK warnings.
For 7.x and earlier branches, `_cat/repositories` API requests require a
repository name.
This removes an erroneous request example without a repository name
added with a8e0275.
Loading shard state information during shard allocation sometimes runs into a situation where a
data node does not know yet how to look up the shard on disk if custom data paths are used.
The current implementation loads the index metadata from disk to determine what the custom
data path looks like. This PR removes this dependency, simplifying the lookup.

With node ordinals gone, there's no longer a need for such a complicated full cluster restart

If a processor executes asynchronously and the ingest simulate api simulates with
multiple documents then the order of the documents in the response may not match
the order of the documents in the request.
Alexander Reelsen discovered this issue with the enrich processor with the following reproduction:
```
PUT cities/_doc/munich
{"zip":"80331","city":"Munich"}
PUT cities/_doc/berlin
{"zip":"10965","city":"Berlin"}
PUT /_enrich/policy/zip-policy
{
"match": {
"indices": "cities",
"match_field": "zip",
"enrich_fields": [ "city" ]
}
}
POST /_enrich/policy/zip-policy/_execute
GET _cat/indices/.enrich-*
POST /_ingest/pipeline/_simulate
{
"pipeline": {
"processors" : [
{
"enrich" : {
"policy_name": "zip-policy",
"field" : "zip",
"target_field": "city",
"max_matches": "1"
}
}
]
},
"docs": [
{ "_id": "first", "_source" : { "zip" : "80331" } } ,

* fixed test compile error
We can simply filter out shard generation updates for indices
that were removed from the cluster state concurrently to fix
index deletes during partial snapshots as that completely removes
any reference to those shards from the snapshot.

This change removes falling back to listing out the repository contents to find the latest `index-N` in write-mounted blob store repositories.
This saves 2-3 list operations on each snapshot create and delete operation. Also it makes all the snapshot status APIs cheaper (and faster) by saving one list operation there as well in many cases.
This removes the resiliency to concurrent modifications of the repository as a result and puts a repository in a `corrupted` state in case loading `RepositoryData` failed from the assumed generation.
Unfortunately bulk delete exceptions don't show the individual delete
errors when a bulk delete fails when you log them outright so I added this work-around
to get the individual details to get useful logging.
This adds a new "xpack.license.upload.types" setting that restricts
which license types may be uploaded to a cluster.
By default all types are allowed (excluding basic, which can only be
generated and never uploaded).
This setting does not restrict APIs that generate licenses such as the
start trial API.
This setting is not documented as it is intended to be set by
orchestrators and not end users.

There's flakiness in CsvProcesorTests, where tests fail if random document generator add field that should not be present. This change cleans generated document from these problematic fields.

G1GC will use humongous allocations when an allocation exceeds half the
chosen region size, which is minimum 1MB. By reducing the recovery
buffer size by 16 bytes we ensure that the recovery buffer is never
allocated as a humongous allocation.
A previous commit taught Elasticsearch packages to respect ES_PATH_CONF
during installs. Missed in that commit was respecting ES_PATH_CONF on
upgrades. This commit does that. Additionally, while ES_PATH_CONF is not
currently used in pre-install, this commit adds respect to the preinst
script in case we do in the future.
In the yaml cluster upgrade tests, we start a scroll in a mixed-version cluster,
then attempt to continue the scroll after the upgrade is complete. This test
occasionally fails because the scroll can expire before the cluster is done
upgrading.
The current scroll keep-alive time 5m. This PR bumps it to 10m, which gives a
good buffer since in failing tests the time was only exceeded by ~30 seconds.
Addresses #46529.
Today we do not consider trimAboveSeqNo when calculating the translog
generation of an index commit. If there is no new indexing after the
primary promotion, then we won't be able to clean up the translog.
