This change makes it possible to compile a separate project with e.g. targetCompatibility 1.7. Adds specific options (compact profile) only when compiling for >= 1.8.
It came out with improvements around idea integration and language levels. This will make it possible to have the upcoming java client as a new project compiled against java 7 and have idea working on the right language level.
When performing a local recovery, the engine replays operations
recovered from the translog into the translog again. These duplicated
operations are eventually cleared after successful recovery on flush,
but there is no need to play these operations into the translog at
all. This commit modifies the local recovery process so as to not replay
these operations into the translog.

This commit adds documentation for the bootstrap checks and provides
either links or inline guidance for setting the necessary settings to
pass the bootstrap checks.

This PR changes the InternalTestCluster to support dedicated master nodes. The creation of dedicated master nodes can be controlled using a new `supportsMasterNodes` parameter to the ClusterScope annotation. If set to true (the default), dedicated master nodes will randomly be used. If set to false, no master nodes will be created and data nodes will also be allowed to become masters. If active, test runs will either have 1 or 3 masternodes
This commit fixes an issue with the plugins directory being a symbolic
link. Namely, the install plugins command attempts to always create the
plugins directory just in case it does not exist. The JDK method used
here guarantees that the directory is created, and an exception is not
thrown if the directory could not be created because it already
exists. The problem is that this JDK method does not respect symlinks so
its internal existence checks fails, it proceeds to attempt to create
the directory, but the directory creation fails because the symlink
exists. This is documented as being not an issue. We work around this by
checking if there is a symlink where we expect the plugins directory to
be, and only attempt to create if not. We add a unit test that plugin
installation to a symlinked plugins directory works as expected.
When mocking unassigned shards which have failed with reason ALLOCATION_FAILED we
have to ensure that the failed allocation counter is strictly positive.
The distributions had their own copies of these extra files, which was a
carry over from maven. This change removes the duplicate files and
copies them from the root of the project.

It looks like the readme was duplicated when plugins were merged back
into the repo. We removed all these extra files from the plugins, this
removes the remaining duplicate from core.
closes#18597
This commit removes the ability to specify a custom plugins
path. Instead, the plugins path will always be a subdirectory called
"plugins" off of the home directory.
This commit simplifies the delayed shard allocation implementation by assigning clear responsibilities to the various components that are affected by delayed shard allocation:
- UnassignedInfo gets a boolean flag delayed which determines whether assignment of the shard should be delayed. The flag gets persisted in the cluster state and is thus available across nodes, i.e. each node knows whether a shard was delayed-unassigned in a specific cluster state. Before, nodes other than the current master were unaware of that information.
- This flag is initially set as true if the shard becomes unassigned due to a node leaving and the index setting index.unassigned.node_left.delayed_timeout being strictly positive. From then on, unassigned shards can only transition from delayed to non-delayed, never in the other direction.
- The reroute step is in charge of removing the delay marker (comparing timestamp when node left to current timestamp).
- A dedicated service DelayedAllocationService, reacting to cluster change events, has the responsibility to schedule reroutes to remove the delay marker.
Closes#18293
Failing the build on deprecation warnings was removed in
19b3ec88af. This commit removes the
suppressed deprecation warnings so that their use is surfaced in the
build now.

This adds modules.txt and plugins.txt to the core jar resource files,
which the install plugin command statically loads, in place of the
previously hardcoded lists (which have often gone out of date).
With the unified release, we will have staged releases based on a
unified hash (hash of all the hashes), so using the elasticsearch hash
for plugins staging will no longer work. This change makes the
`es.plugins.staging` property take the staging hash it should use.
- now you can specify a list of grok patterns to match your field with
and the first one to successfully match wins.
- only non-null captures will be inserted into your matched document.
Fixes#17903.
We have have a virtual build-tools project which pulls in all the same
IDE settings we have for other projects, so there is no longer a need
for hacking buildSrc into our IDEs.
We currently fail on any deprecations found during the build. However,
this includes things deprecated within ES, which adds a heavy burden in
order to deprecate apis (requring to add suppressions to all internal
callers of the API).
This change adds `-deprecation` to xlint. We should consider in the
future having a task to "see" what deprecated apis we currently use for
analysis.
`doc_values` for _type field are created but any attempt to load them throws an IAE.
This PR re-enables `doc_values` loading for _type, it also enables `fielddata` loading for indices created between 2.0 and 2.1 since doc_values were disabled during that period.
It also restores the old docs that gives example on how to sort or aggregate on _type field.
The setting minimum_master_nodes is crucial to avoid split brains in a cluster. In order to avoid data loss, it should always be configured to at least a quorum (majority) of master-eligible nodes.
This commit adds a warning to the logs on the master node if the value is set to less than quorum of master-eligible nodes.
The 'Setting' constructor has some outdated Javadoc that suggested that it would automatically apply 'Property.NodeScope' if no scope is supplied, but no scope is added in that case.
We still maintain BWC for the translog operations back to 1.1 which is not
supported in the current version anyway. This commit drops the bwc and moves
the operations to the Writeable interface enforcing immutability.
