Today we assume that document failures can not occur for deletes. This
assumption is bogus, as they can fail for a variety of reasons such as
the Lucene index having reached the document limit. Because of this
assumption, we were asserting that such a document-level failure would
never happen. When this bogus assertion is violated, we fail the node, a
catastrophe. Instead, we need to treat this as a fatal engine exception.
We currently configure io.netty.allocator.numDirectArenas to be 0 in the
jvm erconomics class. This is a config that we always want to set, so it
makes sense to move it to jvm.options.
This commit adds the `rollover_alias` setting required for ILM to work
correctly to the SLM history index template and adds assertions to the
SLM integration tests to ensure that it works correctly.
Currently, when using script_score functions like cosineSimilarity, the query
vector is treated as an array of doubles. Since the stored document vectors use
floats, it seems like the least surprising behavior for the query vectors to
also be float arrays.
In addition to improving consistency, this change may help with some
optimizations we have been considering around vector dot product.
Today we assume that document failures can not occur for no-ops. This
assumption is bogus, as they can fail for a variety of reasons such as

never happen. When this bogus assertion is violated, we fail the node, a

While the plugin installation directory used to be settable, it has not
been so for several major versions. This commit removes a lingering
reference to the plugins directory in upgrade docs.
closes#45889
Add XContentType as parameter to the
AbstractResponseTestCase#createServerTestInstance method.
In the case a server side response class serializes xcontent as
bytes then the test needs to know what xcontent type was randomily selected.
This change is needed in #45970
Backport of 1a0dddf4ad24b3f2c751a1fe0e024fdbf8754f94 (AKA #445395)
* Add support for a Range field ValuesSource, including decode logic for range doc values and exposing RangeType as a first class enum
* Provide hooks in ValuesSourceConfig for aggregations to control ValuesSource class selection on missing & script values
* Branch aggregator creation in Histogram and DateHistogram based on ValuesSource class, to enable specialization based on type. This is similar to how Terms aggregator works.
* Prioritize field type when available for selecting the ValuesSource class type to use for an aggregation
This commit adds support for `boolean` fields in data frame
analytics (and currently both outlier detection and regression).
The analytics process expects `boolean` fields to be encoded as
integers with 0 or 1 value.
Prior to this commit the foreach action execution had a hard coded
limit to 100 iterations. This commit allows the max number of
iterations to be a configuration ('max_iterations') on the foreach
action. The default remains 100.
Currently the process to execute a reindex process is tightly coupled to
step of initializing the task state. This creates problems when this
process is asynchronous. It is possible that the task state has not been
initialized which prevents follow-up actions such as rethrottle. This
commit separates the task initialization so that it can be executed as a
first step in the persistent reindex process.
This commit extracts the reindexing logic from the transport action so
that it can be incorporated into the persistent reindex work without
requiring the usage of the client.
Currently we use a custom CopyBytesSocketChannel for interfacing with
netty. We have integration tests that use this channel, however we never
verify the read and write behavior in the face of potential partial
writes. This commit adds a test for this behavior.
Searching with `allowPartialSearchResults=false` could still return
partial search results during recovery. If a shard copy fails
with a "shard not available" exception, the failure would be ignored and
a partial result returned. The one case where this is known to happen
is when a shard copy is recovering when searching, since
`IllegalIndexShardStateException` is considered a "shard not available"
exception.
Relates to #42612
Adds a parameter `training_percent` to regression. The default
value is `100`. When the parameter is set to a value less than `100`,
from the rows that can be used for training (ie. those that have a
value for the dependent variable) we randomly choose whether to actually
use for training. This enables splitting the data into a training set and
the rest, usually called testing, validation or holdout set, which allows
for validating the model on data that have not been used for training.
Technically, the analytics process considers as training the data that
have a value for the dependent variable. Thus, when we decide a training
row is not going to be used for training, we simply clear the row's
dependent variable.
The existing privilege model for API keys with privileges like
`manage_api_key`, `manage_security` etc. are too permissive and
we would want finer-grained control over the cluster privileges
for API keys. Previously APIs created would also need these
privileges to get its own information.
This commit adds support for `manage_own_api_key` cluster privilege
which only allows api key cluster actions on API keys owned by the
currently authenticated user. Also adds support for retrieval of
the API key self-information when authenticating via API key
without the need for the additional API key privileges.
To support this privilege, we are introducing additional
authentication context along with the request context such that
it can be used to authorize cluster actions based on the current
user authentication.
The API key get and invalidate APIs introduce an `owner` flag
that can be set to true if the API key request (Get or Invalidate)
is for the API keys owned by the currently authenticated user only.
In that case, `realm` and `username` cannot be set as they are
assumed to be the currently authenticated ones.
The changes cover HLRC changes, documentation for the API changes.
Closes#40031
We recently added a check to `ESIntegTestCase` in order to verify that
no http channels are being tracked when we close clusters and the
REST client. Close listeners though are invoked asynchronously, hence
this check may fail if we assert before the close listener that removes
the channel from the map is invoked.
With this commit we add an `assertBusy` so we try and wait for the map
to be empty.
Closes#45914Closes#45955
This commit introduces PKI realm delegation. This feature
supports the PKI authentication feature in Kibana.
In essence, this creates a new API endpoint which Kibana must
call to authenticate clients that use certificates in their TLS
connection to Kibana. The API call passes to Elasticsearch the client's
certificate chain. The response contains an access token to be further
used to authenticate as the client. The client's certificates are validated
by the PKI realms that have been explicitly configured to permit
certificates from the proxy (Kibana). The user calling the delegation
API must have the delegate_pki privilege.
Closes#34396
This check was introduced in #41392 but had the unwanted side-effect
that the keystore settings in such blocks would note be added in the
node's keystore. Given that we have a mid-term plan for FIPS testing
that would made such checks unnecessary, and that the conditional
in these two cases is not really that important, this change removes
this conditional logic so that full-cluster-restart and rolling
upgrade tests will run with PEM files for key/certificate material
no matter if we're in a FIPS JVM or not.
Resolves: #45475
The root project uses the base plugin to get a clean task, but does not
actually need the assemble task. This commit changes the root project to
use the lifecycle-base plugin, which while still creating the assemble
task, won't add any dependencies to it.
Since #45473, we trim translog below the local checkpoint of the safe
commit immediately if soft-deletes enabled. In
testRestoreLocalHistoryFromTranslog, we should have a safe commit after
recoverFromTranslog is called; then we will trim translog files which
contain only operations that are at most the global checkpoint.
With this change, we relax the assertion to ensure that we don't put
operations to translog while recovering history from the local translog.
If two translog syncs happen concurrently, then one can return before
its operations are marked as persisted. In general, this should not be
an issue; however, peer recoveries currently rely on this assumption.
Closes#29161
Today we create new engines under IndexShard#mutex. This is not ideal
because it can block the cluster state updates which also execute under
the same mutex. We can avoid this problem by creating new engines under
a separate mutex.
Closes#43699
This adds support for verifying that snippets with the `console-result`
language are valid json. It also switches the response snippets on the
`docs/get` page from `js` to `console-result` which will allow clients
to provide "alternatives" for them like they can now do with
`// CONSOLE` snippets.
This commit starts from the simple premise that the use of node settings
in blob store repositories is a mistake. Here we see that the node
settings are used to get default settings for store and restore throttle
rates. Yet, since there are not any node settings registered to this
effect, there can never be a default setting to fall back to there, and
so we always end up falling back to the default rate. Since this was the
only use of node settings in blob store repository, we move them. From
this, several places fall out where we were chaining settings through
only to get them to the blob store repository, so we clean these up as
well. That leaves us with the changeset in this commit.
This adds a pipeline aggregation that calculates the cumulative
cardinality of a field. It does this by iteratively merging in the
HLL sketch from consecutive buckets and emitting the cardinality up
to that point.
This is useful for things like finding the total "new" users that have
visited a website (as opposed to "repeat" visitors).
This is a Basic+ aggregation and adds a new Data Science plugin
to house it and future advanced analytics/data science aggregations.
The native process requires that there be a non-zero number of rows to analyze. If the flag --rows 0 is passed to the executable, it throws and does not start.
When building the configuration for the process we should not start the native process if there are no rows.
Adding some logging to indicate what is occurring.
Backport of #45799
This PR modifies the logic in IngestService to preserve the original content type
on the IndexRequest, such that when a document with a content type like SMILE
is submitted to a pipeline, the resulting document that is persisted will remain in
the original content type (SMILE in this case).
* Pass COMPUTERNAME env var to elasticsearch.bat
When we run bin/elasticsearch with bash, we get a $HOSTNAME builtin that
contains the hostname of the machine the script is running on. When
there's no provided nodename, Elasticsearch uses the HOSTNAME to create
a nodename. On Windows, Powershell provides a $COMPUTERNAME variable for
the same purpose. CMD.EXE provides the same thing, except it's called
%COMPUTERNAME%. bin/elasticsearch.bat sets $HOSTNAME to the value of
$COMPUTERNAME. However, when testclusters invokes bin/elasticsearch.bat,
the COMPUTERNAME variable doesn't get passed in, leaving HOSTNAME null
and breaking an integration test on Windows.
This commit sets COMPUTERNAME in the environment so that our tests get
the value that Elasticsearch would have when bin/elasticsearch.bat is
invoked from the shell.
* Add null check to protect in non-Windows case
What good is it a developer to gain the whole Windows if they forfeit
their Unix? The value that fixes things on Windows is null on
Linux/Darwin, so let's null-check it.
* Override system hostnames for testclusters
Rather than relying on variable system behavior, let's just override
HOSTNAME and COMPUTERNAME and test for correct values in the integration
test that was originally failing.
* Rename constants for clarity
Since we are setting HOSTNAME and COMPUTERNAME regardless of whether the
tests are running on Windows or Linux, we shouldn't imply that constants
are only used in one case or the other.
This is essentially the same issue fixed in #43362 but for http request
version instead of the request method. We have to deal with the
case of not being able to parse the request version, otherwise
channel closing fails.
