Changes the API of GatewayAllocator#applyStartedShards and
GatewayAllocator#applyFailedShards to take both a RoutingAllocation
and a list of shards to apply. This allows better mock allocators
to be created as being done in #20637.
Closes#20642
Removes the FailedRerouteAllocation class and StartedRerouteAllocation
class, as they were just wrappers for RerouteAllocation that stored
started and failed shards, but these started and failed shards can
be passed in directly to the methods that needed them, removing the
need for this wrapper class and extra level of indirection.
Closes#20626
When initializing a new index routing table, we make a decision where the primary shards should be recovered from. This can be an empty folder for new indices, a set of specific allocation ids for old indices or a snapshot. We currently allow callers of `IndexRoutingTable.initializeEmpty` to supply the source but also set it automatically if null is given. Sadly the current logic is reusing the supplied parameter to store the result of the automatic decision. This is flawed if some of the decision should be *different* between the different index shard (as the first decision that is maid sticks).
This commit fixes this but also simplifies the API to always make an automatic decision.
This was discovered while working on #20637 which strengthens the testing infra and caused this to bubble up. I put it as a separate commit to make sure it is not lost as part of a bigger test only PR.
* Removed the check for the correct hash in the `/` response, otherwise two hashes would be needed
* Adapted to new URLs
* Added two missing plugins
* Downloaded gpg key only once
Today we hold on to all possible tokenizers, tokenfilters etc. when we create
an index service on a node. This was mainly done to allow the `_analyze` API to
directly access all these primitive. We fixed this in #19827 and can now get rid of
the AnalysisService entirely and replace it with a simple map like class. This
ensures we don't create a gazillion long living objects that are entirely useless since
they are never used in most of the indices. Also those objects might consume a considerable
amount of memory since they might load stopwords or synonyms etc.
Closes#19828
When testing tribe nodes in an integration test, we should pass the classpath
plugins of the node down to the tribe client nodes. Without this the tribe client
nodes could be prevented from communicating with the tribes.
Today we define a cluster wait condition to try to wait at least a
certain number of nodes when running integration tests. Alas, the wait
condition is incorrect because wait_for_nodes>=${numNodes} will be split
by parameter parsing on the equals sign so the request looks like it has
a parameter named wait_for_nodes>. The fact that REST param parsing is
lenient leads to this being undiscovered. This commit fixes this issue.

Adds an integration test for the file-based discovery plugin
to test the plugin operates correctly and uses the hosts
configured in `unicast_hosts.txt` with a real cluster
Closes#20459
When an active shadow replica is reinitialized during primary promotion, the recovery stats that are used by the allocation decider settings `cluster.routing.allocation.node_concurrent_recoveries` and `cluster.routing.allocation.node_concurrent_incoming_recoveries` have to be updated.
If your native script needs to do some heavy computation on initialization,
the fact that we create a new one for every segment rather than for the whole
index could have a negative performance impact.
We have a "HUGE HACK" that allows us to publish zip artifacts to
Sonatype's OSS repository without javadoc and source jars. We don't
include those jars because the zip is just a repackaging of the
core and module jars for which we already publish the javadoc and
source jars. So we have a hack to publish the zip artifact when the
pom says the project is of type 'pom'.
The build currently depends on the presence of a Git remote named origin to determine the URL that is used in the generated POM file. As this is best-effort anyhow and only required by Maven Central, this commit allows the build to run even if a Git remote with the name "origin" is missing.
With the switch to Log4j 2 the logger usage checker was temporarily disabled. This adapts the checks to work with Log4j 2 and re-enables the Gradle checks. It also fixes the wrong logger usages that have sneaked into the code base.
* plugins/discovery-azure-class.asciidoc
* reference/cluster.asciidoc
* reference/modules/cluster/misc.asciidoc
* reference/modules/indices/request_cache.asciidoc
After this is merged there will be no unconvereted snippets outside
of `reference`.

With the switch to Log4j 2 throughout our code base, the logger usage checker was temporarily disabled. This commit
adapts the checks to work with Log4j 2 and re-enables the Gradle checks.

This commit changes the default behavior of `_flush` to block if other flushes are ongoing.
This also removes the use of `FlushNotAllowedException` and instead simply return immediately
by skipping the flush. Users should be aware if they set this option that the flush might or might
not flush everything to disk ie. no transactional behavior of some sort.
Closes#20569
Translog#read is a left-over from realtime-get that allows to read
from an arbitrary location in the transaction log. This method is unused
and can be replaced with snapshots in tests.
`index.routing.allocation.initial_recovery` is used with index shrinking to make sure the new index's primary is assigned to the node that holds a copy of each of the source index shards. Sadly with the introduction of `RecoverySource` a regression was introduced that limits the allocation of replicas of the new index.
I'm not sure why we need this pom instead of the pom generated by
nebula, but if we are going to have it then we need to populate it
with appropriate stuff like project name, description, and url.
Today when CLI tools are executed, logging statements can intentionally
or unintentionally be executed when logging is not configured. This
leads to log messages that the status logger is not configured. This
commit reworks logging configuration for CLI tools so that logging is
always configured.

This commit removes `ByteSizeValue`'s methods that are duplicated (ex: `mbFrac()` and `getMbFrac()`) in order to only keep the `getN` form.
It also renames `mb()` -> `getMb()`, `kb()` -> `getKB()` in order to be more coherent with the `ByteSizeUnit` method names.
Adds a cat api endpoint: /_cat/templates and its more specific version, /_cat/templates/{name}.
It looks something like:
$ curl "localhost:9200/_cat/templates?v"
name template order version
sushi_california_roll *avocado* 1 1
pizza_hawaiian *pineapples* 1
pizza_pepperoni *pepperoni* 1
The specified version (only allows * globs) looks like:
$ curl "localhost:9200/_cat/templates/pizza*"
name template order version
pizza_hawaiian *pineapples* 1
pizza_pepperoni *pepperoni* 1
Partially specified columns:
$ curl "localhost:9200/_cat/templates/pizza*?v=true&h=name,template"
name template
pizza_hawaiian *pineapples*
pizza_pepperoni *pepperoni*
The help text:
$ curl "localhost:9200/_cat/templates/pizza*?help"
name | n | template name
template | t | template pattern string
order | o | template application order number
version | v | version
Closes#20467
Gradle appears to have a bug in maven publshing which will not match the
artifactId of a generated pom with the artifact id it puts in the file.
This adds back a copy hack from the original pom file name to the client
pom file name (which we had before #20403 inadvertently
removed it).
This commit adds a new test TribeIT#testClusterStateNodes() to verify that the tribe node correctly reflects the nodes of the remote clusters it is connected to.
It also changes the existing tests so that they really use two remote clusters now.
IndexResponse#toString method outputs an error caused by the shards object needing to be wrapped into another object. It is fixed by calling a different variant of Strings.toString(XContent) which accepts a second boolean argument that makes sure that a new object is created before outputting ShardInfo. I didn't change ShardInfo#toString directly as whether it needs a new object or not very much depends on where it is printed out. IndexResponse seemed a specific case as the rest of the info were not json, hence the shards object was the first one, but it is usually not the case.
With the unified release process across the elastic stack, download
links for all products are changing. This change updates docs referring
to the old download and packages urls.
Note that this change also updates the plugin installation command as
the url for downloads is being changed to be consistent with that for
packages (both plural).
The serial collector is not suitable for running with a server
application like Elasticsearch and can decimate performance and lead to
cluster instability. This commit adds a bootstrap check to prevent usage
of the serial collector when Elasticsearch is running in production
mode.

Today when acquiring a prefix logger for a logger info stream, we obtain
a new prefix logger per invocation. This can lead to contention on the
markers lock in the constructor of PrefixLogger. Usually this is not a
problem (because the vast majority of callers hold on to the logger they
obtain). Unfortunately, under heavy indexing with multiple threads, the
contention on the lock can be devastating. This commit modifies
LoggerInfoStream to hold on to the loggers it obtains to avoid
contending over the lock there.
