We make sure to specify include_type_name=true during xContent parsing,
so we continue to test the legacy typed responses. XContent generation
for the typeless responses is currently only covered by REST tests,
but we will be adding unit test coverage for these as we implement
each typeless API in the Java HLRC.
This commit also refactors GetMappingsResponse to follow the same appraoch
as the other mappings-related responses, where we read include_type_name
out of the xContent params, instead of creating a second toXContent method.
This gives better consistency in the response parsing code.
* Fix more REST tests.
* Improve some wording in the create index documentation.
* Add a note about types removal in the create index docs.
* Fix SmokeTestMonitoringWithSecurityIT#testHTTPExporterWithSSL.
* Make sure to mention include_type_name in the REST docs for affected APIs.
* Make sure to use 'expression == false' in FullClusterRestartIT.
* Mention include_type_name in the REST templates docs.
This commit adds a unique id to cluster blocks, so that they can be uniquely
identified if needed. This is important for the Close Index API where multiple
concurrent closing requests can be executed at the same time. By adding a
UUID to the cluster block, we can generate unique "closing block" that can
later be verified on shards and then checked again from the cluster state
before closing the index. When the verification on shard is done, the closing
block is replaced by the regular INDEX_CLOSED_BLOCK instance.
If something goes wrong, calling the Open Index API will remove the block.

* Deprecate types in index API
- deprecate type-based constructors of IndexRequest
- update tests to use typeless IndexRequest constructors
- no yaml tests as they have been already added in #35790
Relates to #35190
The following updates were made:
* Add deprecation warnings to `RestUpdateAction`, plus a test in `RestUpdateActionTests`.
* Deprecate relevant methods on the Java HLRC requests/ responses.
* Add HLRC integration tests for the typed APIs.
* Update documentation (for both the REST API and Java HLRC).
* Fix failing integration tests.
Because of an earlier PR, the REST yml tests were already updated (one version without types, and another legacy version that retains types).
The commit changes how indices are closed in the MetaDataIndexStateService.
It now uses a 3 steps process where writes are blocked on indices to be closed,
then some verifications are done on shards using the TransportVerifyShardBeforeCloseAction
added in #36249, and finally indices states are moved to CLOSE and their routing
tables removed.
The closing process also takes care of using the pre-7.0 way to close indices if the
cluster contains mixed version of nodes and a node does not support the TransportVerifyShardBeforeCloseAction. It also closes unassigned indices.

For each API, the following updates were made:
- Add deprecation warnings to `Rest*Action`, plus tests in `Rest*ActionTests`.
- For each REST yml test, make sure there is one version without types, and another legacy version that retains types (called *_with_types.yml).
- Deprecate relevant methods on the Java HLRC requests/ responses.
- Update documentation (for both the REST API and Java HLRC).
Back in #32983 I broke running the integ-test-zip tests against an
external cluster by adding a test that reads the contents of the log
file. This fixes running against an external cluster by explicitly
skipping that test if running against an external cluster.
When we implemented `refresh=wait_for` I added a test with the wrong
name. This caused us to not run it. The test asserted that running
several operations with `refresh=wait_for` did not fail if the index was
`_close`d while the operations were waiting. But to be honest, failure
here isn't that bad. The index being waited on is closed. You can't do
anything with it any way. The most important thing is actually that
these operations don't hang forever. Because hanging forever means that
the resources used by the operations aren't freed.
Anyway, when I noticed the error I reenabled the test. But they don't
pass consistently because *sometimes* the operations being tested fail.
They don't seem to hang and they always fail with "this index is closed
so you can't do anything with it" sorts of messages.
When the test started failing we disabled it again. This reenables the
test but causes it to ignore these "index is closed" failures. We'd
prefer they not happen at all but in the grand scheme of things they are
fine and making sure these operations don't hang is much more important.
This also updates the test to bring it more in line with my current
understanding of the "right" way to use the low level rest client.
Changes the default of the `node.name` setting to the hostname of the
machine on which Elasticsearch is running. Previously it was the first 8
characters of the node id. This had the advantage of producing a unique
name even when the node name isn't configured but the disadvantage of
being unrecognizable and not being available until fairly late in the
startup process. Of particular interest is that it isn't available until
after logging is configured. This forces us to use a volatile read
whenever we add the node name to the log.
Using the hostname is available immediately on startup and is generally
recognizable but has the disadvantage of not being unique when run on
machines that don't set their hostname or when multiple elasticsearch
processes are run on the same host. I believe that, taken together, it
is better to default to the hostname.
1. Running multiple copies of Elasticsearch on the same node is a fairly
advanced feature. We do it all the as part of the elasticsearch build
for testing but we make sure to set the node name then.
2. That the node.name defaults to some flavor of "localhost" on an
unconfigured box feels like it isn't going to come up too much in
production. I expect most production deployments to at least set the
hostname.
As a bonus, production deployments need no longer set the node name in
most cases. At least in my experience most folks set it to the hostname
anyway.
I created a test a few days ago and declared a package that doesn't line
up with the directory structure. Oops. I a little surprised nothing
complained. But this fixes it.
I disabled one branch a few hours ago because it failed in CI. It looks
like other branches can also fail so I'll disable them as well and look
more closely on Monday.
Change the logging infrastructure to handle when the node name isn't
available in `elasticsearch.yml`. In that case the node name is not
available until long after logging is configured. The biggest change is
that the node name logging no longer fixed at pattern build time.
Instead it is read from a `SetOnce` on every print. If it is unset it is
printed as `unknown` so we have something that fits in the pattern.
On normal startup we don't log anything until the node name is available
so we never see the `unknown`s.
In #29623 we added `Request` object flavored requests to the low level
REST client and in #30315 we deprecated the old `performRequest`s. This
changes all calls in the `client` and `distribution` projects to use
the new versions.

This commit changes the default out-of-the-box configuration for the
number of shards from five to one. We think this will help address a
common problem of oversharding. For users with time-based indices that
need a different default, this can be managed with index templates. For
users with non-time-based indices that find they need to re-shard with
the split API in place they no longer need to resort only to
reindexing.
Since this has the impact of changing the default number of shards used
in REST tests, we want to ensure that we still have coverage for issues
that could arise from multiple shards. As such, we randomize (rarely)
the default number of shards in REST tests to two. This is managed via a
global index template. However, some tests check the templates that are
in the cluster state during the test. Since this template is randomly
there, we need a way for tests to skip adding the template used to set
the number of shards to two. For this we add the default_shards feature
skip. To avoid having to write our docs in a complicated way because
sometimes they might be behind one shard, and sometimes they might be
behind two shards we apply the default_shards feature skip to all docs
tests. That is, these tests will always run with the default number of
shards (one).
This commit moves the distribution specific tasks into the respective
archives and packages builds. The collocation of common and distribution
specific tasks make it much easier to reason about what is expected in a
particular distribution.
This commit adds intermediate gradle projects for archive based
distributions (zip, tar) and package based distributions (rpm, deb). The
grouping allows the common distribution build file to be considerably
shorter and clearly separated from the common zip/tar and rpm/deb
configuration.
