This commit adds a prefix intervals source, allowing you to search
for intervals that contain terms starting with a given prefix. The source
can make use of the index_prefixes mapping option.
Relates to #43198
* [ML][Data Frame] Add support for allow_no_match for endpoints (#43490)
* [ML][Data Frame] Add support for allow_no_match parameter in endpoints
Adds support for:
* Get Transforms
* Get Transforms stats
* stop transforms
* Update DataFrameTransformDocumentationIT.java
Given a nested structure composed of Lists and Maps, getByPath will return the value
keyed by path. getByPath is a method on Lists and Maps.
The path is string Map keys and integer List indices separated by dot. An optional third
argument returns a default value if the path lookup fails due to a missing value.
Eg.
['key0': ['a', 'b'], 'key1': ['c', 'd']].getByPath('key1') = ['c', 'd']
['key0': ['a', 'b'], 'key1': ['c', 'd']].getByPath('key1.0') = 'c'
['key0': ['a', 'b'], 'key1': ['c', 'd']].getByPath('key2', 'x') = 'x'
[['key0': 'value0'], ['key1': 'value1']].getByPath('1.key1') = 'value1'
Throws IllegalArgumentException if an item cannot be found and a default is not given.
Throws NumberFormatException if a path element operating on a List is not an integer.
Fixes#42769
This commit modifies the RemoteInfo to clarify that a search query
must always be serialized as JSON. Additionally, it adds an assertion
to ensure that this is the case. This fixes#43406.
Additionally, this PR implements AbstractXContentTestCase for the
reindex request. This is related to #43456.
This change introduces a new setting,
xpack.ml.process_connect_timeout, to enable
the timeout for one of the external ML processes
to connect to the ES JVM to be increased.
The timeout may need to be increased if many
processes are being started simultaneously on
the same machine. This is unlikely in clusters
with many ML nodes, as we balance the processes
across the ML nodes, but can happen in clusters
with a single ML node and a high value for
xpack.ml.node_concurrent_job_allocations.
A voting-only master-eligible node is a node that can participate in master elections but will not act
as a master in the cluster. In particular, a voting-only node can help elect another master-eligible
node as master, and can serve as a tiebreaker in elections. High availability (HA) clusters require at
least three master-eligible nodes, so that if one of the three nodes is down, then the remaining two
can still elect a master amongst them-selves. This only requires one of the two remaining nodes to
have the capability to act as master, but both need to have voting powers. This means that one of
the three master-eligible nodes can be made as voting-only. If this voting-only node is a dedicated
master, a less powerful machine or a smaller heap-size can be chosen for this node. Alternatively, a
voting-only non-dedicated master node can play the role of the third master-eligible node, which
allows running an HA cluster with only two dedicated master nodes.
Closes#14340

Today the `ClusterFormationFailureHelper` says `... discovery will continue
using ... from last-known cluster state` and lists all the nodes in the
last-known cluster state. In fact we ignore the master-ineligible nodes in the
last-known cluster state during discovery. This commit fixes this by listing
only the master-eligible nodes from the cluster state in this message.
This commit changes the `role_descriptors` field from required
to optional when creating API key. The default behavior in .NET ES
client is to omit properties with `null` value requiring additional
workarounds. The behavior for the API does not change.
Field names (`id`, `name`) in the invalidate api keys API documentation have been
corrected where they were wrong.
Closes#42053
If the master removes the relocating shard, but recovery isn't aware of
it, then we can enter an invalid state where ReplicationTracker does not
include the local shard.
Now that the fix krb5-kdc fixture (entropy problem in docker container)
is in and the converting `kerberos-tests` to testclusters is done,
enabling the kerberos-tests

* Enhance TimeValue.toString() to allow specifying fractional values.
This enhances the `TimeValue` class to allow specifying the number of
truncated fractional decimals when calling `toString()`. The default
remains 1, however, more (or less, such as 0) can be specified to change
the output.
This commit also re-organizes some things in `TimeValue` such as putting
all the class variables near the top of the class, and moving the
constructors to the first methods in the class, in order to follow the
structure of our other code.
* Rename `toString(...)` to `toHumanReadableString(...)`
Today we assert that a warning is logged after no more than
`discovery.cluster_formation_warning_timeout`, but the deterministic scheduler
adds a small amount of extra randomness to the timing of future events, causing
the following build to fail:
./gradlew :server:test --tests "org.elasticsearch.cluster.coordination.CoordinatorTests.testLogsWarningPeriodicallyIfClusterNotFormed" -Dtests.seed=DF35C28D4FA9EE2D
This commit adds an allowance for this extra time.
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)
closes#43413
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.
