Currently, we check if a node has the same set of custom metadata as the master
before joining the cluster. This implies freshly installing a plugin that has its
custom metadata requires a full cluster restart.
Currently, we silently accept malformed query where more
than one key is defined at the top-level for query object.
If all the keys have a valid query body, only the last query
is executed, besides throwing off parsing for additional suggest,
aggregation or highlighting defined in the search request.
This commit throws a parsing exception when we encounter a query
with multiple keys.

The default of 30s causes some tests to timeout when running ensureGreen and similar. This is because network delays simulation blocks connect until either the connect timeout expires or the disruption configured time stops. We do *not* immediately connect when the disruption is stopped.
The only repository we can be sure is safe to clean is `fs` so we clean
any snapshots in those repositories after each test. Other repositories
like url and azure tend to throw exceptions rather than let us fetch
their contents during the REST test. So we clean what we can....
Closes#18159
`profile.asciidoc` now runs all of its command but it doesn't validate
all of the results. Writing the validation is time consuming so I only
did some of it.
Today when starting Elasticsearch without a Log4j 2 configuration file,
we end up throwing an array index out of bounds exception. This is
because we are passing no configuration files to Log4j. Instead, we
should throw a useful error message to the user. This commit modifies
the Log4j configuration setup to throw a user exception if no Log4j
configuration files are present in the config directory.

The test uses a NetworkDelay that drops requests and slows down connecting. Next to that it disable node fault detection to make sure nodes are not removed before we check our publishing. Sadly that can lead to huge slow downs if the disruption hits while a node is still pinging (and tries to connect, which is slowed down). Instead we can start the disruption on the cluster state thread, making sure the result of fault detection won't be processed before we publish
LongGCDisruption simulates a Long GC by suspending all threads belonging to a node. That's fine, unless those threads hold shared locks that can prevent other nodes from running. Concretely the logging infrastructure, which is shared between the nodes, can cause some deadlocks. LongGCDisruption has protection for this, but it needs to be updated to point at log4j2 classes, introduced in #20235
This commit also fixes improper handling of retry logic in LongGCDisruption and adds a protection against deadlocking the test code which activates the disruption (and uses logging too! :)).
On top of that we have some new, evil and nasty tests.
Currently we always pass -E to the the plugin cli with the conf dir, but
this causes a very confusing error message when not giving a specific
command to the plugin cli. This change makes path.conf pass just like
path.home. These are special settings, so passing via sysprops is the
right thing to do (it is all about how we pass between shell and java
cli).

This was actually a byproduct of trying to remove a //norelease for
index shard setting validation in MetaDataIndexService. This //norelease
is now removed. Previously this check was *only* used by the template
service, so we validated twice, once in the Settings infrastructure and
once when actually creating the index. We now instead use the Settings
infrastructure to validate the settings for shard count.
`TransportService#registerRequestHandler` allowed to register
handlers more than once and issues an annoying warn log message when
this happens. This change simple throws an exception to prevent regsitering
the same handler more than once. This commit also removes the ability
to remove request handlers.

The refresh description should indicate that the affected shards are
refreshed as opposed to the entire index.
This was raised as a discrepancy on
discuss (https://discuss.elastic.co/t/refresh-parameter-of-index-api/59008/2)
on the .NET client that originates from code generated from the rest api
spec. The description has been updated in master but should be updated
for the 2.4.0 release.
BATS upgrade tests fails on master branch because it tries to install 2.x versions to upgrade from instead of 5.x versions. And since #18554 we should only test upgrades from 5.0.0-alpha4 versions.
This commit changes the vagrant tests so that it tries to list all the previous releases from version N-1. If nothing is found, it will fetch the current version and will run the upgrade tests with it. It works nicely with the current master 6.0.0-alpha1-SNAPSHOT. Once 5.0.0 is released it should run the test with it.
When uninstalling or upgrading elasticsearch using the RPM package some empty directories remain on the filesystem:
/usr/share/elasticsearch/bin
/usr/share/elasticsearch/lib
/usr/share/elasticsearch/modules
/usr/share/elasticsearch/modules/foo
Having empty directories in modules can prevent elasticsearch to start after an upgrade: the plugins service expects to find a plugin-descriptor.properties file in every sub directory of modules.
This PR cleans things a bit so that these empty directories are removed on upgrade/removal like it was in 2.x.
* Update rescoring docs in respect to sort
If sort is present in a query the rescore query is not executed. As long as this feature is neither implemented (see discussion in #6788) nor the combination of sort and rescoring raises an error, we should warn the user in the documentation about this.
* Missed a dot
The Log4j shutdown hack test tests that a hack we have in place to
workaround a bug in Log4j during shutdown is effective. Log4j can use
JMX to control logging levels, but we disable this through the use of a
system property log4j2.disable.jmx (mainly because there is no need for
this feature, but it also means granting additional security
permissions). The bug in Log4j is that during shutdown, it neglects to
check whether or not its usage of JMX is disable and so it attempts to
unregister management beans, leading to a permissions violation. The
test works by attempting to shutdown Log4j and thus triggering the bad
code path. With the Log4j hack in place, we have introduced jar hell so
that its our code running instead of code from the Log4j jar. Our code
correctly checks that the usage of JMX is disabled and thus does not
trip on a permissions violation. The test was a little complicated in
that it attempted to just grant the minimal permissions needed for Log4j
to do its thing, but this can sometimes lead to other unwanted
permissions violations because the permissions put in place are more
restrictive necessary. This commit simplifies this situation by
rewriting the test to only deny Log4j the sole permission needed to
trigger the bug.

We still use some crazy poor mans compression in InternalSearchHit that
uses a thread local and an unordered map as a lookup table if requested.
Stuff like this should be handled by compression on the transport layer
rather than in-line in the serialization code. This code is complex enough.
In 7560101ec7, the Elasticsearch logger
names were modified to be their fully-qualified class name (with some
exceptions for special loggers like the slow logs and the transport
tracer). This commit updates the docs accordingly.

This utility class is used in 3 places while we only need to register
the handlers once per node. Otherwise we will see nasty `WARN` logs like:
`registered two transport handlers for action indices:data/read/search[phase/fetch/id/scroll]...`
This change will only register handlers inside the main TransportSearchAction.
When upgrading elasticsearch using the RPM package, the scripts directory is removed if it's empty but it won't be recreated by the upgraded package. But after that the service won't start because the scripts dir is missing.
After this change SearchModule doesn't subclass AbstractModule anymore and all wiring
happens in `Node.java`. As a side-effect several tests don't need a guice injector anymore.
This commit modifies the logger names within Elasticsearch to be the
fully-qualified class name as opposed removing the org.elasticsearch
prefix and dropping the class name. This change separates the root
logger from the Elasticsearch loggers (they were equated from the
removal of the org.elasticsearch prefix) and enables log levels to be
set at the class level (instead of the package level).
Relates #20457
Today when setting the logging level via the command-line or an API
call, the expectation is that the logging level should trickle down the
hiearchy to descendant loggers. However, this is not necessarily the
case. For example, if loggers x and x.y are already configured then
setting the logging level on x will not descend to x.y. This is because
the logging config for x.y has already been forked from the logging
config for x. Therefore, we must explicitly descend the hierarchy when
setting the logging level and that is what this commit does.

update geoip to not include null-valued results from database
Originally, the plugin would still insert all the requested fields, but
assign null to each one. This fixes that by not writing the fields at
all. Makes for a better experience when the null fields conflict with
the typical geo_point field mapping.
This commit introduces a new plugin for file-based unicast hosts
discovery. This allows specifying the unicast hosts participating
in discovery through a `unicast_hosts.txt` file located in the
`config/discovery-file` directory. The plugin will use the hosts
specified in this file as the set of hosts to ping during discovery.
The format of the `unicast_hosts.txt` file is to have one host/port
entry per line. The hosts file is read and parsed every time
discovery makes ping requests, thus a new version of the file that
is published to the config directory will automatically be picked
up.
Closes#20323
With the cut over to LatLonPoint the geohash, geohash_precision, lat_lon, and geohash_prefix parameters have been removed. This commit fixes the doc build by removing the remaining dangling references to these removed parameters.
This commit fixes the following geo_point bwc tests:
* GeoDistanceIT to test deprecated GeoDistanceRangeQuery on legacy indexes only.
* ExternalFieldMapperTests to correctly handle LatLonPoint type
* GeoPointFieldMapperTests to correctly test stored geo_point fields
