Today we throw ElasticsearchException if we can't lock the index. This can cause
problems since some places where we have logic to deal with IOException on shard
deletion won't schedule a retry if we can't lock the index dir for removal. This
is the case on shadow replicas for instance if a shared FS is used. The result
of this is that the delete of an index is never acked.
A change in #12116 introduces closing / cleaning of search ctx even if
the index service was closed due to a relocation of it's last shard. This
is not desired since in that case it's fine to serve the pending requests from
the relocated shard. This commit adds an extra check to ensure that the index is
either removed (delete) or closed via API.
The term query parser was too lenient during parsing and allowed to specify
more than one field, even though this expected to filter only for a single field.
This commit returns an exception if a query has been specified more than once.
Closes#12184
Modified ScriptEngineService to pass in a CompiledScript object
with newly added name and type member variables.
This can in turn be used to give better scripting error messages
with the type of script used and the name of the script.
Required slight modifications to the caching mechanism.
Note that this does not enforce good behavior in that plugins will
have to write exceptions that also output the name of the script
in order to be effective. There was no way to wrap the script
methods in a try/catch block properly further up the chain because
many have script-like objects passed back that can be run at a
later time.

This PR is a simple doc patch to explicitly mention with an example of
how to create an alias using a glob pattern. This comes up from
time-to-time with our customers and in the community and although
mentioned in the documentation already, is not obvious.
Also mention that the alias will not auto-update as indices matching the
glob change.
Closes#12175Closes#12176
ignore_above is used to guard against the lucene limitation
that a term cannot exceed 32766 bytes.
However, the implementation just used the character count, which
doesn't take into account the fact that some characters have
multi-byte utf-8 encodings.
This commit updates the docs to make this relationship clear.
Closes#11563
Changes in a nutshell:
* All expression logic is now encapsulated by ExpressionResolver interface.
* MetaData#convertFromWildcards() gets replaced by WildcardExpressionResolver.
* All of the indices expansion methods are being moved from MetaData class to the new IndexNameExpressionResolver class.
* All single index expansion optimisations are removed.
The logic for resolving a concrete index name from an expression has been moved from MetaData to IndexExpressionResolver. The logic has been cleaned up and simplified were was possible without breaking bwc.
Also the notion of aliasOrIndex has been changed to index expression.
The IndexNameExpressionResolver translates index name expressions into concrete indices. The list of index name expressions are first delegated to the known ExpressionResolverS. An ExpressionResolver is responsible for translating if possible an expression into another expression (possibly but not required this can be concrete indices or aliases) otherwise the expressions are left untouched. Concretely this means converting wildcard expressions into concrete indices or aliases, but in the future other implementations could convert expressions based on different rules.
To prevent many overloading of methods, DocumentRequest extends now from IndicesRequest. All implementation of DocumentRequest already did implement IndicesRequest indirectly.
This allows the creation of the RPM artifact as part of the
maven package phase. The result of this is that we get checksum and
name correction for-free as it's all build an installed into the m2
repository. This also publishes the RPM together with .deb to the mvn
mirror.
Note: this will only build the RPM as part of the package phase if
`-Dpackage.rpm=true` since the binaries to build the RPM are not
availabel on all platforms.
Today we only clear search contexts for deleted indies. Yet, we should
do the same for closed indices to ensure they can be reopened quickly.
Closes#12116
A method for the new Script API were missing in the ValuesSourceMetricsAggregationBuilder. This change adds the missing method and deprecates the old Script API methods
When a node sends a shard started message to the master, the master goes through the routing table looking for the shard to start. At the moment we validate the indexUUID, the node the shard is assigned to and the fact that the shard is initializing. This check goes wrong if a relocating replica shard finishes recovery just at the moment the source node leaves the cluster. In this case the master will cancel the recovery and will likely assign a new initializing replica to the same target node. In this case the message from the relocation recovery can activate the new replica wrongfully.
Also, the logic for decided whether an incoming shard started message will be applied was split between ShardStateAction and the AllocationService.
This commit does the following:
1) Let ShardStateAction only filter basic stuff like index existence and indexUUID.
2) Move the trickier shard started matching logic to the AllocationService and make it stricter
3) Unify ShardStateAction filtering logic for both shard started and shard failed.
4) Add unit tests for all of the above.
For an example test failure see: http://build-us-00.elastic.co/job/es_core_16_centos/388/Closes#11999
Today everything is tight to having the next version as the latest.
In order to work towards 2.0.0.beta1 we need to fix all the usage of
2.0.0-SNAPSHOT to reflect the version we will release soon.
Usually we do this on the release branch but to simplify things I wanna
keep this on master for now and move to 2.1.0-SNAPSHOT on master once
we created a 2.0 branch.
Closes#12148
This information was stored with the snapshot but wasn't available on the interface. Knowing the version of elasticsearch that created the snapshot can be useful to determine the minimal version of the cluster that is required in order to restore this snapshot.
Closes#11980
This change fixes the plugin manager to trim `elasticsearch-` and `es-` prefixes from plugin names
for our official plugins. This restores the old behavior prior to #11805.
Closes#12143
Today it will remove all permissions and only set execute bit:
---x--x--x
Instead we should preserve existing permissions, and just add
read and execute to whatever is there.
Closes#12142
This change allows custom settings to be passed to the client for the external test cluster,
which is necessary when additional settings need to be passed to the client in order to
properly communicate with the external test cluster.
