When installed as a service with a DEB or RPM package, we should gently wait for elasticsearch to stop (flushing indices on closing can take some time) and never kill the process.
Closes#11248
Moved the license checker config into the parent pom, and overrede
the license dir/target-to-check in distributions/pom.
Disabled the license checker explicitly for projects which run integration
tests but have no licenses dir:
* core
* distribution
* qa
* plugins/delete-by-query
* plugins/mapper-size
* plugins/site-example

This commit adds basic support to track the number of times scripts are
compiled and compiled scripts are evicted from the script cache. These
statistics are tracked at the node level.
Closes#12673
This commit updates the Zen Discovery documentation to explain which
nodes partcipate in master election (by default) as well as the
configuration parameters for controlling this.
Closes#12727
Bats testing uncovered a useless systemctl check, that resulted in an
error, because the systemctl file was uninstalled, but we hoped to
check for an explicetely configured SystemExitCode.
In addition we did not reload the systemctl configuration when uninstalling
elasticsearch, which now is fixed as well.
Closes#12682
this commit adds a simple integration test that starts a
node from a shaded jar, indexes a doc and retrieves it. It
also has some basic unittests that try to load shaded classes and ensure
that their counterpart is not in the classpath.
Closes#12711
Elasticsearch will create this if it doesn't exist if it cant but because
it doesn't own /etc/elasticsearch when installed by rpm and deb it can't
create /etc/elasticsearch/scripts.
Closes#12702
ClusterState has 3 different methods to access RoutingNodes:
* #routingNodes() - mutable version
* #getRoutingNodes() - delegates to #getReadOnlyRoutingNodes()
* #getReadOnlyRoutingNodes() - it's docs say `NOTE, the routing nodes are mutable, use them just for read operations`
The latter also reuses the instance that it creates. This has several problems beside the obvious:
* creating RoutingNodes is costly and should be done only if really needed ie. use cached version as much as possible
* the common case is ReadOnly but all kinds of things are called
* mutable version are only needed in one place and should only be used in the AllocationService
* RoutingNodes can freeze it's ShardRoutings but doesn't
* RoutingNodes should check if it's read-only or not
This commit fixed all the problems and special cases the mutable case such that all accesses via ClusterState#getRoutingNodes()
is read-only and RoutingNodes enforces this.
This is one of our esoteric metadata mappers so I think we should distribute
it in a plugin rather than in elasticsearch core.
This introduces one limitation: the value of the `_size` parameter is not
retrievable for documents that are only in the transaction log.
The `multi_match` query groups terms that have the same analyzer together and
then applies the boost of the first query in each group. This is not necessary
given that boosts for each term are already applied another way.
