Made AckedClusterStateUpdateTask an abstract class instead of an interface, which contains the common methods.
Also introduced the AckedRequest interface to mark both AcknowledgedRequest & ClusterStateUpdateRequest so that the different ways of updating the cluster state (with or without a MetaData*Service) can share the same code.
Removed ClusterStateUpdateListener as we can just use its base class ActionListener instead.
Closes#6559
Sandboxes the groovy scripting language with multiple configurable
whitelists:
`script.groovy.sandbox.receiver_whitelist`: comma-separated list of string
classes for objects that may have methods invoked.
`script.groovy.sandbox.package_whitelist`: comma-separated list of
packages under which new objects may be constructed.
`script.groovy.sandbox.class_whitelist` comma-separated list of classes
that are allowed to be constructed.
As well as a method blacklist:
`script.groovy.sandbox.method_blacklist`: comma-separated list of
methods that are never allowed to be invoked, regardless of target
object.
The sandbox can be entirely disabled by setting:
`script.groovy.sandbox.enabled: false`
Introduced the use of the FilterClient in all of the REST actions, which delegates all of the operations to the internal Client, but makes sure that the headers are properly copied if needed from REST requests to TransportRequest(s) when it comes to executing them.
Added new abstract handleRequest method to BaseRestHandler with additional Client argument and made private the client instance member (was protected before) to force the use of the client received as argument.
The list of headers to be copied over is by default empty but can be extended via plugins.
Closes#6513
After #6517 we ended up registering all of the actions (included admin ones) to the NodeClient.
Made sure that only the proper type of Action instances are registered to each client type.
Also fixed some compiler warnings: unused members, imports and non matching generic types.
Closes#6563
Mid-term we should switch from `BytesValues` to Lucene's doc values APIs, in
particular the `SortedSetDocValues` class. While `BytesValues.WithOrdinals` and
SortedSetDocValues expose the same functionality, `BytesValues.WithOrdinals`
exposes its ordinals via a different `Ordinals.Docs` object while
`SortedSetDocValues` exposes them on the same object as the one that holds the
values. This commit merges ordinals into `BytesValues.WithOrdinals` in order to
make both classes even closer.
Global ordinals were a bit tricky to migrate so I just changed them to use
Lucene's OrdinalMap that will soon (LUCENE-5767, scheduled for 4.9) have the
same optimizations as our global ordinals.

The `exists` and `missing` filters need to merge postings lists of all existing
terms, which can be very costly, especially on high-cardinality fields. This
commit indexes the field names of a document under `_field_names` and reuses it
to speed up the `exists` and `missing` filters.
This is only enabled for indices that are created on or after Elasticsearch
1.3.0.
Close#5659
VersionFieldMapper.defaultDocValuesFormat claims that the default is `disk`.
This is not used to choose the DV format in the index but for mappings
serialization in order to know when the _version doc values format is
different from the default format. This made it impossible to use the `disk`
doc values format since mappings would never retain that information at
serialization time.
Close#6523
The TTL, size, timestamp and index meta properties could be lost on an
update of a single field mapping due to a wrong comparison in the
merge method (which was caused by a wrong initialization, which marked
an update as explicitely disabled instead of unset.
Closes#5053
Added the http.jsonp.enable option to configure disabling of JSONP responses, as those
might pose a security risk, and can be disabled if unused.
This also fixes bugs in NettyHttpChannel
* JSONP responses were never setting application/javascript as the content-type
* The content-type and content-length headers were being overwritten even if they were set before
Closes#6164
Commit fbd7c9aa5d introduced a regression that caused
the min_doc_count to be equal to the number of documents in the
background set. As a result no buckets were built when the
response for significant terms was created.
This only affected the final XContent response.

Currently we send relocation & flush actions based on all assigned ShardRoutings. During the final stage of relocation, we may miss to refresh/flush a shard if the coordinating node has not yet processed the cluster state update indicating that a relocation is completed *and* the relocation target node has already processed it (i.e., started the shard and has accepted new indexing requests).
Closes#6545
Percentile Rank Aggregation is the reverse of the Percetiles aggregation. It determines the percentile rank (the proportion of values less than a given value) of the provided array of values.
Closes#6386
Nested documents were indexed as separate documents, but it was never checked
if the hits represent nested documents or not. Therefore, nested objects could
match not nested queries and nested queries could also match not nested documents.
Examples are in issue #6540 .

Client, ClusterAdminClient and IndicesAdminClient had corresponding
intermediate `internal` interfaces that are unnecessary and cause
a lot of casting. This commit removes the intermediate interfaces
and uses the super interfaces directly.
This commit also adds Releaseable to `Node` and `Client` in order to
be used with utilities like try / with.

This commit renames `TestCluster` -> `InternalTestCluster` and
`ImmutableTestCluster` to `TestCluster` for consistency. This also
makes `ExternalTestCluster` and `InternalTestCluster` consistent
with respect to their execution environment.
Closes#6510
This commit add a basic infrastructure as well as primitive tests
to ensure version backwards compatibility between the current
development trunk and an arbitrary previous version. The compatibility
tests are simple unit tests derived from a base class that starts
and manages nodes from a provided elasticsearch release package.
Use the following commandline executes all backwards compatiblity tests
in isolation:
```
mvn test -Dtests.bwc=true -Dtests.bwc.version=1.2.1 -Dtests.class=org.elasticsearch.bwcompat.*
```
These tests run basic checks like rolling upgrades and
routing/searching/get etc. against the specified version. The version
must be present in the `./backwards` folder as
`./backwards/elasticsearch-x.y.z`
The alias -> (index -> alias) map, specifically the index -> alias one, typically just hold one entry, yet we eagerly initialize it to the number of indices. When there are many indices, each with many aliases, this is a very large overhead per alias...
