The script APIs have been deprecated long ago we can now remove them.
This commit still keeps the parsing code since it might be used in a
query that is still stuck in transaction log. This issue should be discussed
elsewhere.
Closes#11619
In order to restrict a single set of field type settings for a given
field name across an index, we need the ability to compare field types.
This change adds equals and hashcode, as well as tests for every field
type.
Make sure there is a single place where shard routing move to unassigned, so we can add additional metadata when it does, also, simplify shard routing implementations a bit
closes#11634
When we build a plugin, we suppose it will be executed within elasticsearch server.
So we should mark it as `provided`.
If a java developer needs to embed the plugin and elasticsearch, it will make sense to declare both in its `pom.xml` file.
The 'Building From Source' section of README.textile was misleading as it said that the release can be found in `target/releases` when they are actually now found in the `target/releases` folder of each module.
The AsyncShardFetch retrieves shard information from the different nodes in order to detirment the best location for unassigned shards. The class uses TransportNodesListGatewayStartedShards and TransportNodesListShardStoreMetaData in order to fetch this information. These actions, inherit from TransportNodesAction and are activated using a list of node ids. Those node ids are extracted from the cluster state that is used to assign shards.
If we perform a reroute and adding new news in the same cluster state update task, it is possible that the AsyncShardFetch administration is based on
a different cluster state then the one used by TransportNodesAction to resolve nodes. This can cause a problem since TransportNodesAction filters away unkown nodes, causing the administration in AsyncShardFetch to get confused.
This commit fixes this allowing to override node resolving in TransportNodesAction and uses the exact node ids transfered by AsyncShardFetch
Information about in-progress snapshot and restore processes is not really metadata and should be represented as a part of the cluster state similar to discovery nodes, routing table, and cluster blocks. Since in-progress snapshot and restore information is no longer part of metadata, this refactoring also enables us to handle cluster blocks in more consistent manner and allow creation of snapshots of a read-only cluster.
Closes#8102
This commit cleans up all the MergeScheduler infrastructure
and simplifies / removes all unneeded abstractions. The MergeScheduler
itself is now private to the Engine and all abstractions like Providers
that had support for multiple merge schedulers etc. are removed.
Closes#11602
This is helpful to track down the origin of pending_tasks that aren't
expected. In tests we catch this with an assert, but in production
asserts may not be enabled so we should at least add the class name.
Today we provide the ability to plug in MergePolicy and
we provide the once lucene ships with. We do not recommend to change
the default and even only a small number of expert users would ever touch
this. This commit removes the ancient log byte size and log doc count
merge policy providers, simplifies the MergePolicy wiring and makes the
tiered MP the one and only default. All notions of a merge policy has been
removed from the docs and should be deprecated in the previous version.
Closes#11588
There used to be a null check for _field_names mapper not existing. This
was recently removed. However, there is a corner case when the mapper
may be missing: when no types or docs exist at all in the index.
This change adds back a null check and just returns no docs.
The current ExceptionsHelper.unwrapCause(exception) requires the incoming exception to support ElasticsearchWrapperException , which TranslogRecoveryPerformer.BatchOperationException doesn't implement. I opted for a more generic solution
