The deleted counter is incremented even if the document is missing. Also, this commit ensures that the scroll id is cleared even if no documents are found by the scan request.
`com.google.common.collect.Iterators#emptyIterator()` is marked as deprecated and will be removed in May 2016. We should use JDK7 `Collections#emptyIterator()`
By setting human parameter to true, it's now possible to see human readable versions of Elasticsearch that created and updated the index as well as the date when the index was created.
Closes#11484
This changes the parameter name `ignore_like` to the more user friendly name
`unlike`. This later feature generates a query from the terms in `A` but not
from the terms in `B`. This translates to a result set which is like `A` but
unlike `B`. We could have further negatively boosted any documents that have
some `B`, but these documents already do not receive any contribution from
having `B`, and would therefore negatively compete with documents having `A`.
Closes#11117
this is really just a workaround for plugins to run their own
REST tests instead of the core ones. It opts out of the rest test
loading from the core jar file and tries to load from the classpath instead.
Eventually we need to fix this infrastrucutre to move away from parameterized
tests such that subclasses can override behavior.
Closes#11721
Added a licenses/ directory to core which contains a sha1 file for each JAR
dependency, and one or more LICENSE files and one NOTICE file for each
project.
Also adds dev-tools/src/main/resources/license-check/check_license_and_sha.pl
which checks that the licenses/ dir is up to date during a mvn verify,
and which can be used to update the sha1 files when upgrading dependencies.

This change adds a simplistic heuristic to try to balance new shard
allocations across multiple data paths on one node so that e.g. if
there are two path.data and both have roughly the same free space, if
10 shards are suddenly allocated, we will put 5 on one path and 5 on
the other (vs 10 on a single path today).

The delete by query plugin adds support for deleting all of the documents (from one or more indices) which match the specified query. It is a replacement for the problematic delete-by-query functionality which has been removed from Elasticsearch core in 2.0. Internally, it uses the Scan/Scroll and Bulk APIs to delete documents in an efficient and safe manner. It is slower than the old delete-by-query functionality, but fixes the problems with the previous implementation.
Closes#7052
Unassigned meta includes additional information as to why a shard is unassigned, this is especially handy when a shard moves to unassigned due to node leaving or shard failure.
The additional data is provided as part of the cluster state, and as part of `_cat/shards` API.
The additional meta includes the timestamp that the shard has moved to unassigned, allowing us in the future to build functionality such as delay allocation due to node leaving until a copy of the shard is found.

Since the /var/run/elasticsearch directory is cleaned when the operating system starts, the init.d script must ensure that the PID_DIR is correctly created.
Closes#11594
The cache we are using for fielddata reclaims memory lazily/asynchronously. While this
helps with throughput this is an issue when a clear operation is issued manually since
memory is not reclaimed immediately. Since our clear methods already perform in linear
time anyway, this commit changes the fielddata cache to reclaim memory synchronously
when a clear command is issued manually. However, it remains lazy in case cache entries
are invalidated because segments or readers are closed, which is important since such
events happen all the time.
Close#11695
Some of our Java api builders had wrong logic when it comes to serializing the query in json format, resulting in missing fields like _name. Also, regexp parser was ignoring the _name field.
Closes#11694
`_timestamp` uses NumericDocValues instead of SortedNumericDocValues like other
numeric fields since it is guaranteed to be single-valued. However, we don't
need a different fielddata impl for it since DocValues.getSortedNumeric already
falls back to NUMERIC doc values if SORTED_NUMERIC are not available.
[doc] fix outdated java api examples
Some API have been changed in master. Master documentation should reflect be updated:
* QueryBuilders.queryString is now QueryBuilders.queryStringQuery
* DateHistogram.Interval is now DateHistogramInterval
* Refactoring of buckets in aggs
* FilterBuilders has been replaced by QueryBuilders
Closes#9976.

[build] mark elasticsearch as provided in plugins
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.
[maven] clean pom.xml
In Maven parent project, in dependency management, we should only declare which versions of 3rd party jars we want to use but not force any scope.
It makes then more obvious in modules what is exactly the scope of any dependency.
For example, one could imagine importing `jimfs` as a `compile` dependency in another module/plugin with:
```xml
<dependency>
<groupId>com.google.jimfs</groupId>
<artifactId>jimfs</artifactId>
</dependency>
```
But it won't work as expected as the default maven `scope` should be `compile` but here it's `test` as defined in the parent project.
So, if you want to use this lib for tests, you should simply define:
```xml
<dependency>
<groupId>com.google.jimfs</groupId>
<artifactId>jimfs</artifactId>
<scope>test</scope>
</dependency>
```
We also remove `maven-s3-wagon` from gce plugin as it's not used.
This was previously a container for an ObjectMapper, along with the
DocumentMapper that ObjectMapper came from. However, there was
only one use of needing the associated DocumentMapper, and that
wasn't actually used.

Now that doc values are the default for fielddata, specialized in-memory
formats are becoming an esoteric option. This commit removes such formats:
- `fst` on string fields,
- `compressed` on geo points.
I also removed documentation and tests that the fielddata cache is shared if
you change the format, since this is only true for in-memory fielddata formats
(given that for doc values, the caching is done directly in Lucene).
