Aggregatable mutli-fields are at the moment wrongly mapped
as normal doc_value fields and thus they support fetching from
source. However, they do not exist in the source. This results
to failure to extract such fields.
This commit fixes this bug. While a fix could be worked out
on top of the existing code, it is evident the extraction logic
has become difficult to understand and maintain. As we also
want to deduplicate multi-fields for data frame analytics,
it seemed appropriate to refactor the code to simplify and
better handle the extraction of multi-fields.

* Introduce binary_format request parameter (binary.format for JDBC) to disable binary
communication between clients (jdbc/odbc) and server.
* for CLI - "binary" command line parameter (or -b) is introduced. Default value is "true".
* binary communication (cbor) is enabled by default
* disabling request parameter introduced for debugging purposes only

* Add ingest info to Cluster Stats (#48485)
This commit enhances the ClusterStatsNodes response to include global
processor usage stats on a per-processor basis.
example output:
```
...
"processor_stats": {
"gsub": {
"count": 0,
"failed": 0
"current": 0
"time_in_millis": 0
},
"script": {
"count": 0,
"failed": 0
"current": 0,
"time_in_millis": 0
}
}
...
```
The purpose for this enhancement is to make it easier to collect stats on how specific processors are being used across the cluster beyond the current per-node usage statistics that currently exist in node stats.
Closes#46146.
* fix BWC of ingest stats
The introduction of processor types into IngestStats had a bug.
It was set to `null` and set as the key to the map. This would
throw a NPE. This commit resolves this by setting all the processor
types from previous versions that are not serializing it out to
`_NOT_AVAILABLE`.
This test used an index without an alias to simulate a failure in the
`check-rollover-ready` step. However, with #48256 that step
automatically retries, meaning that the index may not always be in
the ERROR step.
This commit changes the test to use a shrink action with an invalid
number of shards so that it stays in the ERROR step.
Resolves#48767
Previous behavior while copying HTTP headers to the ThreadContext,
would allow multiple HTTP headers with the same name, handling only
the first occurrence and disregarding the rest of the values. This
can be confusing when dealing with multiple Headers as it is not
obvious which value is read and which ones are silently dropped.
According to RFC-7230, a client must not send multiple header fields
with the same field name in a HTTP message, unless the entire field
value for this header is defined as a comma separated list or this
specific header is a well-known exception.
This commits changes the behavior in order to be more compliant to
the aforementioned RFC by requiring the classes that implement
ActionPlugin to declare if a header can be multi-valued or not when
registering this header to be copied over to the ThreadContext in
ActionPlugin#getRestHeaders.
If the header is allowed to be multivalued, then all such headers
are read from the HTTP request and their values get concatenated in
a comma-separated string.
If the header is not allowed to be multivalued, and the HTTP
request contains multiple such Headers with different values, the
request is rejected with a 400 status.
This commit simplifies the JDK copy specification in the archives build
so that it's a single line as opposed to an if/else with a repeated
body. This approach reduces the maintenance cost of this code.
* Always pass user-specified MaxDirectMemorySize
We had been testing whether a user had passed a value for
MaxDirectMemorySize by parsing the output of "java -XX:PrintFlagsFinal
-version". If MaxDirectMemorySize equals zero, we set it to half of max
heap. The problem is that on Windows with JDK 8, a JDK bug incorrectly
truncates values over 4g and returns multiples of 4g as zero. In order
to always respect the user-defined settings, we need to check our input
to see if an "-XX:MaxDirectMemorySize" value has been passed.
* Always warn for Windows/jdk8 ergo issue
Even if a user has set MaxDirectMemorySize, they aren't future-proof for
this JDK bug. With this change, we issue a general warning for the
windows/JDK8 issue, and a specific warning if MaxDirectMemorySize is
unset.
This commit eliminates some custom logic we have in place for post-hoc
cleanup of POM files generated by Gradle. There were to main issues this
logic was meant to address:
First, for dependencies marked as `transitive = false`, Gradle by
default creates a "wildcard" exclusion in the generated POM file. It
turns out that Ivy didn't handle these types of exclusions well, even
though they are perfectly valid and dealt with by Gradle and Maven as
expected. We've since confirmed that this issues is indeed resolved in
the most recent Ivy release (2.5.0-rc1) so going forward the suggestion
to folks consuming Elasticsearch dependencies with Ivy will be to use
this version.
Second, earlier versions of Gradle would incorrectly assign compile
dependencies to the "runtime" scope in the publish POM file. This could
cause issues if the dependencies were indeed needed at compile time
because their APIs were exposed. This has since been fixed and these
dependencies are correctly marked as "compile" scope in the POM.
Since these two issues have been resolved in their respective projects
we can eliminate this logic and all the supporting code, such as having
to create lots of "internal" configurations for tracking transitive
dependencies.
Fix an issue that arises from the use of ExpressionIds as keys in a lookup map
that helps the QueryTranslator to identify the grouping columns. The issue is
that the same expression in different parts of the query (SELECT clause and GROUP BY clause)
ends up with different ExpressionIds so the lookup fails. So, instead of ExpressionIds
use the hashCode() of NamedExpression.

This adds the infrastructure to be able to retry the execution of retryable
steps and makes the `check-rollover-ready` retryable as an initial step to
make the rollover action more resilient to transient errors.

Today a couple of allocation deciders iterate through all the shards on a node
to find the `INITIALIZING` or `RELOCATING` ones, and this can slow down cluster
state updates in clusters with very high-density nodes holding many thousands
of shards even if those shards belong to closed or frozen indices. This commit
pre-computes the sets of `INITIALIZING` and `RELOCATING` shards to speed up
this search.

Backport of #48553. Make a number of changes so that JSON in the server
directory is more resilient to automatic formatting. This covers:
* Reformatting multiline JSON to embed whitespace in the strings
* Add helper method `stripWhitespace()`, to strip whitespace from a JSON
document using XContent methods. This is sometimes necessary where
a test is comparing some machine-generated JSON with an expected
value.
Today it is possible that we import a dangling index that was created in a
newer version than one or more of the nodes in the cluster. Such an index would
prevent the older node(s) from rejoining the cluster if they were to briefly
leave it for some reason. This commit prevents the import of such dangling
indices.
Fixes#34264
This commit adds a new :test:fixtures:azure-fixture project which
provides a docker-compose based container that runs a AzureHttpFixture
Java class that emulates an Azure Storage service.
The logic to emulate the service is extracted from existing tests and
placed in AzureHttpHandler into the new project so that it can be
easily reused. The :plugins:repository-azure project is an example
of such utilization.
The AzureHttpFixture fixture is just a wrapper around AzureHttpHandler
and is now executed within the docker container.
The :plugins:repository-azure:qa:microsoft-azure project uses the new
test fixture and the existing AzureStorageFixture has been removed.
At present the ML C++ artifact is always downloaded from
S3. This change adds an option to configure the location.
(The intention is to use a file:/// URL to pick up the
artifact built in a Docker container in ml-cpp PR builds
so that C++ changes that will break Java integration tests
can be detected before the ml-cpp PRs are merged.)

After some consideration, we are electing to make "ubi" part of the
image name instead of part of the tag. This commit implements that
change for the Elasticsearch UBI-based Docker images.
Moves common field extraction logic to its own package so that it can
be used both for anomaly detection and data frame analytics.
In preparation for refactoring extraction fields to be simpler and to
support multi-fields properly.
Backport of #48709
When we load a JSON Web Key (JWKSet) from the specified
file using JWKSet.load it internally uses IOUtils.readFileToString
but the opened FileInputStream is never closed after usage.
https://bitbucket.org/connect2id/nimbus-jose-jwt/issues/342
This commit reads the file and parses the JWKSet from the string.
This also fixes an issue wherein if the underlying file changed,
for every change event it would add another file watcher. The
change is to only add the file watcher at the start.

* Un-AwaitsFix and enhance logging for testPolicyCRUD
This removes the `AwaitsFix` and increases the test logging for
`SnapshotLifecycleServiceTests.testPolicyCRUD` in an effort to track
down the cause of #44997.
* Remove unused import
This PR performs the following changes:
* Split `ScoreScriptUtilsTests` into `DenseVectorFunctionTests` and
`SparseVectorFunctionTests`. This will make it easier to delete all sparse
vector function tests once we remove support on 8.x.
* As much as possible, break up the large test methods into individual tests
for each vector function (`cosineSimilarity`, `l2norm`, etc.).
This commit finishes cleaning up the AbstractHlrcXContentTestCase work
and removes this class. All classes that were using this are now using
the updated base class.
Ref #39745
The old graph tests were duplicated a lot and used a deprecated parent
class. This commit cleans that up and removes one of the duplicated
tests.
Ref #39745
The logger was erroneously using the `SnapshotLifecycleMetadata` class
for its initialization, making it hard to target packages for logging
levels since `SnapshotLifecycleMetadata` is in a different package.
With this change, we won't warm up searchers until we externally refresh
an engine. We explicitly refresh before allowing reading from a shard
(i.e., move to post_recovery state) and during resetting. These
guarantees that we have warmed up the engine before exposing the
external searcher.
Another prerequisite for #47186.
* [ML][Inference] separating definition and config object storage (#48651)
This separates out the `definition` object from being stored within the configuration object in the index.
This allows us to gather the config object without decompressing a potentially large definition.
Additionally, `input` is moved to the TrainedModelConfig object and out of the definition. This is so the trained input fields are accessible outside the potentially large model definition.
This adds a guard for the SLM lifecycle and retention service that
prevents new jobs from being scheduled once the service has been
stopped. Previous if the node were shut down the service would be
stopped, but a cluster state or local master election would cause a job
to attempt to be scheduled. This could lead to an uncaught
`RejectedExecutionException`.
