Today we only handle correctly if the `ExecutionCancelledException` comes from the
local execution. Yet, this can also come from remove and should be handled identically.
This commit restores the chunk size of 512kb lost in a previous but unreleased
refactoring. At the same time it removes the configurability of:
* `indices.recovery.file_chunk_size` - now fixed to 512kb
* `indices.recovery.translog_ops` - removed without replacement
* `indices.recovery.translog_size` - now fixed to 512kb
* `indices.recovery.compress` - file chunks are not compressed due to lucene's compression but translog operations are.
The compress option is gone entirely and compression is used where it makes sense. On sending files of the index
we don't compress as we rely on the lucene compression for stored fields etc.

This commit cherry picks some infrastructure changes from the `feature/seq_no` branch to make merging from master easier.
More explicitly, IndexShard current have prepareIndex and prepareDelete methods that are called both on the primary as the replica, giving it a different origin parameter. Instead, this commits creates two explicit prepare*OnPrimary and prepare*OnReplica methods. This has the extra added value of not expecting the caller to use an Engine enum.
Also, the commit adds some code reuse between TransportIndexAction and TransportDeleteAction and their TransportShardBulkAction counter parts.

The tribe node creates one local client node for each cluster it
connects to. Refactorings in #13383 broke this so that each local client
node now tries to load the full elasticsearch.yml that the real tribe
node uses.
This change fixes the problem by adding a TribeClientNode which is a
subclass of Node. The Environment the node uses is now passed in (in
place of Settings), and the TribeClientNode simply does not use
InternalSettingsPreparer.prepareEnvironment.
The tests around tribe nodes are not great. The existing tests pass, but
I also manually tested by creating 2 local clusters, and configuring and
starting a tribe node. With this I was able to see in the logs the tribe
node connecting to each cluster.

I don't recall of this property of any of our field mappers and it's not in our
docs so I suspect it's very old. The removal of this property will not fail
version upgrades since none of the field mappers use it in toXContent.
This commit removes some unneeded null checks from
IndexingMemoryController that were left over from the work in #15251,
and simplifies the try-catch block in
IndexingMemoryController#updateShardBuffers.
For the search refactoring the HighlightBuilder needs a way to
create new instances by parsing xContent. For bwc this PR start
by moving over and slightly modifying the parsing from
HighlighterParseElement and keeps parsing for top level highlighter
and field options separate. Also adding tests for roundtrip
of random builder (rendering it to xContent and parsing it and
making sure the original builder properties are preserved)
Since 2.2 we run all scripts with minimal privileges, similar to applets in your browser.
The problem is, they have unrestricted access to other things they can muck with (ES, JDK, whatever).
So they can still easily do tons of bad things
This PR restricts what classes scripts can load via the classloader mechanism, to make life more difficult.
The "standard" list was populated from the old list used for the groovy sandbox: though
a few more were needed for tests to pass (java.lang.String, java.util.Iterator, nothing scary there).
Additionally, each scripting engine typically needs permissions to some runtime stuff.
That is the downside of this "good old classloader" approach, but I like the transparency and simplicity,
and I don't want to waste my time with any feature provided by the engine itself for this, I don't trust them.
This is not perfect and the engines are not perfect but you gotta start somewhere. For expert users that
need to tweak the permissions, we already support that via the standard java security configuration files, the
specification is simple, supports wildcards, etc (though we do not use them ourselves).
This commit simplifies shard inactive debug logging to only log when the
physical shard is marked as inactive. This eliminates duplicate logging
that existed in IndexShard#checkIdle and
IndexingMemoryController#checkIdle, and eliminates excessive logging
that was occurring when the shard was already inactive as a result of
the work in #15252.
Currently, when a user tries to install an old plugin (pre 2.x) on a 2.x
node, the error message is cryptic (just printing the file path that was
missing, when looking for the descriptor). This improves the message to
be more explicit that the descriptor is missing, and suggests the
problem might be the plugin was built before 2.0.

This commit addresses some issues that arose during the review of #14899
but were lost during squash while integrating into master.
- the number of test threads is dropped to at most eight
- a local variable is renamed for clarity
- task priorities are randomized
This commit fixes a test bug in
ClusterService#testClusterStateBatchedUpdates. In particular, in the
case that an executor did not receive a task assignment from the random
assignments, it would not have an entry in the map of executors to
counts of assigned tasks. The fix is to just check if each executor has
an entry in the counts map.
This commit modifies IndexingMemoryController to be stateless. Rather
than statefully tracking the indexing status of shards,
IndexingMemoryController can grab all available shards, check their idle
state, and then resize the buffers based on the number of and which
shards are not idle.
The driver for this change is a performance regression that can arise in
some scenarios after #13918. One scenario under which this performance
regression can arise is if an index is deleted and then created
again. Because IndexingMemoryController was previously statefully
tracking the state of shards via a map of ShardIds, the new shards with
the same ShardIds as previously existing shards would not be detected
and therefore their version maps would never be resized from the
defaults. This led to an explosion in the number of merges causing a
degradation in performance.
Closes#15225
Today we only check mapping compatibility when adding mappers to the
lookup structure. However, at this stage, the mapping has already been merged
partially, so we can leave mappings in a bad state. This commit removes the
compatibility check from Mapper.merge entirely and performs it _before_ we
call Mapper.merge.
One minor regression is that the exception messages don't group together errors
that come from MappedFieldType.checkCompatibility and Mapper.merge. Since we
run the former before the latter, Mapper.merge won't even have a chance to let
the user know about conflicts if conflicts were discovered by
MappedFieldType.checkCompatibility.
Close#15049
The `translated` flag makes LineStringBuilder stateful and gets set
to true under certain conditions when building a Shape or Geometry
from the ShapeBuilder. This makes building operations not be idempotent,
so calling build() more than once on a LineStringBuilder might change the
builder itself. This PR fixes this by replacing the instance variable by
a local `translated` flag that is only updated internally during the
building process and created again on any subsequent calls to build()
or buildGeometry().
Failures to merge a mapping can either come as a MergeMappingException if they
come from Mapper.merge or as an IllegalArgumentException if they come from
FieldTypeLookup.checkCompatibility. I think we should settle on one: this pull
request replaces all usage of MergeMappingException with
IllegalArgumentException.
The ttl could be specified as a time value only via the REST layer. That is now possible via java api too, either as a string or as a proper TimeValue. The internal format in IndexRequest becomes now TimeValue, which will then still converted to a long before storing the document.
Closes#15047
- Supports ImmutableOpenIntMap besides java.util.Map and ImmutableOpenMap
- Map keys can be any value (not only String)
- Map values do not have to implement Diffable interface. In that case custom value serializer needs to be provided.
Several settings have been deprecated or are replaced with new settings after refactorings
in version 1.x. This commit removes the support for these settings.
The settings are:
* `index.shard.recovery.translog_size`
* `index.shard.recovery.translog_ops`
* `index.shard.recovery.file_chunk_size`
* `index.shard.recovery.concurrent_streams`
* `index.shard.recovery.concurrent_small_file_streams`
* `indices.recovery.max_size_per_sec`
