After two recent changes (#38824 and #33888), the _cat/indices API
no longer report information for active recovering indices and
non-replicated closed indices. It also misreport replicated closed
indices that are potentially not authorized for the user.
This commit changes how the cat action works by first using the
Get Settings API in order to resolve authorized indices. It then uses
the Cluster State, Cluster Health and Indices Stats APIs to retrieve
information about the indices.
Closes#39933
This merges the initial work that adds a framework for performing
machine learning analytics on data frames. The feature is currently experimental
and requires a platinum license. Note that the original commits can be
found in the `feature-ml-data-frame-analytics` branch.
A new set of APIs is added which allows the creation of data frame analytics
jobs. Configuration allows specifying different types of analysis to be performed
on a data frame. At first there is support for outlier detection.
The APIs are:
- PUT _ml/data_frame/analysis/{id}
- GET _ml/data_frame/analysis/{id}
- GET _ml/data_frame/analysis/{id}/_stats
- POST _ml/data_frame/analysis/{id}/_start
- POST _ml/data_frame/analysis/{id}/_stop
- DELETE _ml/data_frame/analysis/{id}
When a data frame analytics job is started a persistent task is created and started.
The main steps of the task are:
1. reindex the source index into the dest index
2. analyze the data through the data_frame_analyzer c++ process
3. merge the results of the process back into the destination index
In addition, an evaluation API is added which packages commonly used metrics
that provide evaluation of various analysis:
- POST _ml/data_frame/_evaluate
This refactors AggregatorTestCase to allow testing mock scripts.
The main change is to QueryShardContext. This was previously mocked,
but to get the ScriptService you have to invoke a final method
which can't be mocked.
Instead, we just create a mostly-empty QueryShardContext and populate
the fields that are needed for testing. It also introduces a few
new helper methods that can be overridden to change the default
behavior a bit.
Most tests should be able to override getMockScriptService() to supply
a ScriptService to the context, which is later used by the aggs.
More complicated tests can override queryShardContextMock() as before.
Adds a test to MaxAggregatorTests to test out the new functionality.
This test is likely to kill the server in the middle of writing logs. This means that we can end up with logs with partially written json log lines and standard json parsers would fail on this.
This fix is to use regular expressions on json logs.(just like the previous approach on plain text logs)

The error message if the native controller failed to run
(for example due to running Elasticsearch on an unsupported
platform) was not easy to understand. This change removes
pointless detail from the message and adds some hints about
likely causes.
Fixes#42341
At the end of a peer recovery the primary wants to mark the replica as in-sync. For that the
persisted local checkpoint of the replica needs to have caught up with the global checkpoint on the
primary. If translog durability is set to ASYNC, this means that information about the persisted local
checkpoint can lag on the primary and might need to be explicitly fetched through a global
checkpoint sync action. Unfortunately, that action will only be triggered after 30 seconds, and, even
worse, will only run based on what the in-sync shard copies say (see
IndexShard.maybeSyncGlobalCheckpoint). As the replica has not been marked as in-sync yet, it is
not taken into consideration, and the primary might have its global checkpoint equal to the max seq
no, so it thinks nothing needs to be done.
Closes#43486
This change adds the ability to attach annotative information for
classes, methods, fields, static methods, class bindings, and
instance bindings during Painless whitelisting.
Annotations are specified as @annotation or optionally as
@annotation[parameter="argument",...].
Annotations open up the ability to specify whitelist objects as
having a short name (no_import -> @no_import) or deprecated.
Long and Double ValuesSource set the current document on the script
before executing, but Bytes was missing this method call. That meant
it was possible to generate an OutOfBoundsException when using
a "value" script (field + script) on keyword or other bytes
fields.
This adds in the method call, and a few yaml tests to verify correct
behavior.
Currently nio implements ip filtering at the channel context level. This
is kind of a hack as the application logic should be implemented at the
handler level. This commit moves the ip filtering into a channel
handler. This requires adding an indicator to the channel handler to
show when a channel should be closed.
This commit ensures that ILM's Shrink action will take node versions into
account when choosing which node to allocate to when shrinking an
index. Prior to this change, ILM could pick a node with a lower version
than some shards are already allocated to, which causes the new
allocation to fail as shards can't be relocated onto a node with a lower
version than they are already on.
As part of this, when making the decision about which node to allocate
to prior to Shrink, all shards in the index are considered, rather than
choosing a random shard to consider.
Further, the unit tests for the logic that chooses a node to allocate
shards to pre-shrink has been improved to validate the behavior in more
realistic and varied initial conditions.
This commit performs the proper restore of network disruption.
Previously disruptionScheme.stopDisrupting() was called that does not
ensure that connectivity between cluster nodes is restored. The test
was checking that the cluster has green status, but it was not checking
that connectivity between nodes is restored.
Here we switch to internalCluster().clearDisruptionScheme(true) which
performs both checks before returning.

This commit replaces usages of Streamable with Writeable for the
AcknowledgedResponse and its subclasses, plus associated actions.
Note that where possible response fields were made final and default
constructors were removed.
This is a large PR, but the change is mostly mechanical.

Unsupported HTTP methods are detected during requests dispatching
which generates an appropriate error response. Sadly, this error is
never sent back to the client because the method of the original
request is checked again in DefaultRestChannel which throws again
an IllegalArgumentException that is never handled.
This pull request changes the DefaultRestChannel so that the latest
exception is swallowed, allowing the error message to be sent back
to the client. It also eagerly adds the objects to close to the toClose
list so that resources are more likely to be released if something
goes wrong during the response creation and sending.
We currently assert that adding deletion tombstones to Lucene must always succeed if it's not a
tragic exception, and the same should also hold true for NOOP tombstones. We rely on this
assumption, as without this, we have the risk of creating gaps in the history, which will break
operation-based recoveries and CCR.
The existing language was misleading about the model snapshots and where they are located. Saying "to disk" sounds like files external to Elasticsearch IMO. It raises the obvious question, where on disk? which node? Is it in the Elasticsearch snapshot repo? The model snapshots are held in an internal index.
Depending on git configuration, line feed on checked out files may be
platform dependent, which causes problems to some msearch tests as the
line separator must always be `/n`. With this change we move two files
to the test code so that we control exactly what line separator is used,
given that the corresponding tests fail on windows.
