Instead of using the '-f' parameter to start elasticsearch in the
foreground, this is now the default modus.
In order to start elasticsearch in the background, the '-d' parameter
can be used.
Closes#4392
The `text` query was replaced by the `match` query and has been
deprecated for quite a while.
The `field` query should be replaced by a `query_string` query with
the `default_field` specified.
Fixes#4033
If the term suggester is used the results are merged depending on
the number of terms produced by the tokenizer / tokenfilter. If a
term suggester is executed across multiple indices that share the
same field but with different analysis chains we can't merge the
result anymore sicne tokens are our of order or have a different size.
This commit throws ESIllegalArgumentException if the number of entries
are not the same across all results.
Closes#3196
This commit changes field data configuration updates so that they are
immediately taken into account for loading new segments. The way it works
is that field data configuration is now cached separately from the field
data cache, meaning that it is now possible to clear the field data
configuration from IndexFieldDataService while the cache will stay around. On
the next time that Elasticsearch will reload field data configuration, it will
check if there is already a cache entry, and reuse it if it exists.
To disable field data loading, all that is required is to change the field
data format to "none" (supported by all field data types) using the update
mapping API. Elasticsearch will then refuse to load field data on any new
segment, but field data which has been loaded on the previous segments will
remain available. So you need to clear the field data cache in order to
reclaim memory (otherwise memory will be reclaimed slower, as segments get
merged).

Currently we miss to reset the source shards status to ACTIVE if we cancel
a relocation. If the shard is RELOCATING we need to reset to state ACTIVE.
Closes#4457
Currently the RoutingNodes API allows modification of it's internal state outside of the class.
This commit improves the APIs of `RoutingNode` and `RoutingNode` to change internal state
only within the classes itself.
Closes#4458
Fixes#4334
The deadlock occurs between monitor object of EsThreadPoolExecutor and mainLock of ThreadPoolExecutor. The shutdown method of EsThreadPoolExecutor obtains the lock on monitor first and waits for mainLock of ThreadPoolExecutor in ThreadPoolExecutor#shutdown for part of the processing, while EsThreadPoolExecutor#terminated is executed under mainLock and tries to obtain monitor to notify listeners.
if the MockDirWrapper checks the index on close it closes all
closeables that is has to crash the index if something is not flushed yet.
For us this is a problem since the input is still used. We need to fix this in
lucene first.
When the ValuesSource has ordinals, terms ordinals are used as a cache key to
bucket ordinals. This can make terms aggregations on String terms significantly
faster.

The percolator uses this option to deal with the fact that the MemoryIndex doesn't support stored fields,
this is possible b/c the _source of the document being percolated is always present.
Closes#4348
Before, people that cloned the repo and expected to be able to run
bin/elasticsearch would be met with an awful shell error: the shell
interprets Maven variables like ${project.build.finalName} as shell
variables yet can't handle names of the form ${x.y}. This commit
explicitly checks to make sure that Maven has done its substitutions
before continuing; if Maven hasn't been run, it gives a helpful error
message.
Fixes#2954.
This adds support for Lucene's SimpleQueryParser by adding a new type
of query called the `simple_query_string`. The `simple_query_string`
query is designed to be able to parse human-entered queries without
throwing any exceptions.
Resolves#4159
It could happen although we internally use IgnoreIndices.MISSING, due to MetaData#concreteIndices contract, which throws IndexMissingException anyway if all requested indices are missing.
In case all the indices specified in the query/filter are missing, we just execute the no_match query/filter, no need to throw any error.
Closes#3428
Increased also default publish state timeout to 30 seconds (from 5 seconds) and introduced constant for it.
Introduced AcknowledgedRequest.DEFAULT_ACK_TIMEOUT constant.
Removed misleading default values coming from the REST layer.
Removed (in a bw compatible manner) the timeout support in put/delete index template as the timeout parameter was ignored.
Closes#4395
