We only work with heap byte buffers at this point and those we can and do unwrap the
`byte[]` ourselves and use `BytesArray` instead of a needless level of indirection via `ByteBuffer`.
Backport of #60742.
This PR resurrects support for building Docker images based on one of
Red Hat's UBI images. It also adds support for running the existing
Docker tests against the image. The image is named
`elasticsearch-ubi8:<version>`.
I also changed the Docker build file uses enums instead strings in a lot
of places, for added rigour.
There is a corner case here in which during partial snapshot the index is
deleted right between starting the snapshot in the CS and the data node getting to work
on it, causing the data node the fail that shard snapshot and making the snapshot `PARTIAL`.

Adds an important admonition for the built-in `metrics-*-*` and `logs-*-*` index
templates.
Updates several put index template snippets to include a priority.
Adds a method to make a random date `DateFormatter` pattern. We expect
this'll be useful for runtime fields to compate their formatting with
the standard date field.
Currently we occasionally can get ArithmeticException from parsing bad input
values on 'date' fields that are passed on even if 'ignore_malformed' is set.
This change adds this exception to the ones we already catch for malformed
values.
Closes#52634
* Some progress on failing runtime fields tests (bring #61098 to 7.x)
This breaks apart the a test for the `terms` aggregation into one that
work for runtime fields and one that doesn't.
Breaks up an integration test into one that runtime fields can run and
one that runtime fields have to skip. This is because runtime fields
don't have global ords and we assert things *about* global ords in the
test we have to skip.
Today we allocate a new `byte[]` for each document written to the
cluster state. Some of these documents may be quite large. We need a
buffer that's at least as large as the largest document, but there's no
need to use a fresh buffer for each document.
With this commit we re-use the same `byte[]` much more, only allocating
it afresh if we need a larger one, and using the buffer needed for one
round of persistence as a hint for the size needed for the next one.
The 7.x branch preserves the legacy discovery mechanism from 6.x purely
for running internal cluster tests; this mechanism is otherwise
completely untested and unsupported. However it is still technically
possible to use it outside of the test suite if you dig through the
source code to work out what settings need to be set. With this change
we make it impossible to use this mechanism in production.
Closes#61177
We leverage artifact transforms now when downloading and unpacking elasticsearch distributions.
This has the benefit of
- handcrafted extract tasks on the root project are not required.
- the general tight coupling to the root project has been removed.
- the overall required configurations required to handle a distribution have been reduced
- ElasticsearchDistribution has been simplified by making Extracted an ordinary Configuration
downloaded and unpacked external distributions are reused in later builds by been cached
in the gradle user home.
DistributionDownloadPlugin functional tests have been extended and ported
to DistributionDownloadPluginFuncTest.
* Fix java8 compliant Path calculation
With Gradle 6.6 we can now use the native support for the --release compile options.
As Gradle by default resolves the compatibility version from the release property we needed to workaround this in order to keep our current setup. An issue was raised at gradle to track this at https://github.com/gradle/gradle/issues/14141
feature_processors allow users to create custom features from
individual document fields.
These `feature_processors` are the same object as the trained model's pre_processors.
They are passed to the native process and the native process then appends them to the
pre_processor array in the inference model.

When the ML annotations index was first added, only the
ML UI wrote to it, so the code to create it was designed
with this in mind. Now the ML backend also creates
annotations, and those mappings can change between
versions.
In this change:
1. The code that runs on the master node to create the
annotations index if it doesn't exist but another ML
index does also now ensures the mappings are up-to-date.
This is good enough for the ML UI's use of the
annotations index, because the upgrade order rules say
that the whole Elasticsearch cluster must be upgraded
prior to Kibana, so the master node should be on the
newer version before Kibana tries to write an
annotation with the new fields.
2. We now also check whether the annotations index exists
with the correct mappings before starting an autodetect
process on a node. This is necessary because ML nodes
can be upgraded before the master node, so could write
an annotation with the new fields before the master node
knows about the new fields.
Backport of #61107
#61059 changed this test to only pass include_type_name for 6.8+.
However, the parameter was introduced in 6.7 and should be specified in
6.7+.
Closes#61111
This commit changes the value for client name canonicalization to true
in the krb5.conf template file. This is done as a means to workaround
JDK-8246193 which has made it into some builds of JDK8.
Closes#61050
The ReloadSecureSettingsIT makes requests to the reload settings apis.
In 7.x, the client used from the integ test infrastructure may be a
transport client. In that case, the expected exception type, and causes
the test to fail (though it will hang indefinitely due to not counting
down the latch, see
https://github.com/elastic/elasticsearch/pull/60800). This commit adds
unwrapping of the remote exception to get the underlying expected
exception.
closes#51546
The reaper is used only when spawned processes by the build like
testclusters or vagrant are left behind in a failed build. When this
occurs on Windows, the Taskkill command is used. However, there was a
typo in the command name. Since the reaper is for edgecases and mostly
protection for local builds (CI uses immutable hosts), this has been
broken since its inception.
closes#60503
Use transport blocking to make relocation take forever instead of relying on the relocation to take long enough to clash with the snapshot.
Closes#61069
When a user upgrades between versions, they may stop their ML jobs.
Then when the upgrade is complete, they will want to open the jobs again.
But, when opening a job, we attempt to clear out the jobs finished_time. If the job configuration has adjusted between the versions (i.e. added a new field), it will dynamically update the .ml-config index.
We should instead manually change the mapping to be the updated version.
Followup to #60216, fixing the formatting of
`transport.tcp.reuse_address` and clarifying some wording around the
distinction between the transport and HTTP layers.
