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.

Fixes a test failure in which we allocated some shards and then
relocated them elsewhere, invalidating an assertion about the recovery
statistics which assumed that the shards stayed where they were
originally allocated.
Closes#61067.
This commit fixes the version check for when to specify the
include_type_name request parameter in the FullClusterRestartIT test
that forces the creation of a system index in the old cluster. The
parameter only exists in 6.8, so we need to guard against sending the
parameter to pre-6.8 versions.
It is disastrous if we commit an incremental cluster state update
without having written the full state first. We assert that this doesn't
happen, but it is hard to fully test the myriad ways that things might
fail in a messy production environment. Given the disastrous
consequences it is worth erring on the side of caution in this area.
This commit fails invalid writes even if assertions are disabled.
Changes:
* Moves "Notes" sections for the joining queries and percolate query
pages to the parent page
* Adds related redirects for the moved "Notes" pages
* Assigns explicit anchor IDs to other "Notes" headings. This was required for
the redirects to work.
This commit adds the `data_hot`, `data_warm`, `data_cold`, and `data_frozen` node roles to the
x-pack plugin. These roles are intended to be the base for the formalization of data tiers in
Elasticsearch.
These roles all act as data nodes (meaning shards can be allocated to them). Nodes with the existing
`data` role acts as though they have all of the roles configured (it is a hot, warm, cold, and
frozen node).
This also includes a custom `AllocationDecider` that allows the user to configure the following
settings on a cluster level:
- `cluster.routing.allocation.require._tier`
- `cluster.routing.allocation.include._tier`
- `cluster.routing.allocation.exclude._tier`
And in index settings:
- `index.routing.allocation.require._tier`
- `index.routing.allocation.include._tier`
- `index.routing.allocation.exclude._tier`

Converting AllFieldMapper to parametrized form ended up not being run through BWC
testing, resulting in an incorrect implementation being committed. This commit fixes
the serialization, and adds unit tests as well as unmuting the BWC test that uncovered
the bug.
Fixes#60986
This adds a frozen phase to ILM that will allow the execution of the
set_priority, unfollow, allocate, freeze and searchable_snapshot actions.
The frozen phase will be executed after the cold and before the delete phase.

Elasticsearch currently blocks writes by default when a master is unavailable. The cluster.no_master_block setting allows
a user to change this behavior to also block reads when a master is unavailable. This PR introduces a way to now also still
allow writes when a master is offline. Writes will continue to work as long as routing table changes are not needed (as
those require the master for consistency), or if dynamic mapping updates are not required (as again, these require the
master for consistency).
Eventually we should switch the default of cluster.no_master_block to this new mode.
Today a snapshot repository verification ensures that all master-eligible and data nodes have write access to the
snapshot repository (and can see each other's data) since taking a snapshot requires data nodes and the currently
elected master to write to the repository. However, a dedicated voting-only master-eligible node is not a data node and
will never be the elected master so we should not require it to have write access to the repository.
Closes#59649
Repositories can't be unregistered when they are actively being used for snapshots or restores. Wildcard repository
deletes could silently bypass the "repo in use" checks however, which is now fixed.
`foreach` processors store information within the `_ingest` metadata object.
This commit adds the contents of the `_ingest` metadata (if it is not empty).
And will append new inference results if the result field already exists.
This allows a `foreach` to execute and multiple inference results being written to the same result field.

This makes KeywordFieldMapper extend ParametrizedFieldMapper, with explicitly
defined parameters.
In addition, we add a new option to Parameter, restrictedStringParam, which
accepts a restricted set of string options.
Found this while checking if I can speed up SnapshotResiliencyTests
to get more coverage/time. Turns out throwing a new instance here on
every task was taking 9% of the CPU wall-time in those tests. With
this change it's 4% of the overall.
The Query string parser was not delegating the construction of wildcard/regex queries to the underlying field type.
The wildcard field has special data structures and queries that operate on them so cannot rely on the basic regex/wildcard queries that were being used for other fields.
