All the ordinary test operations happen based on the ImmutableTestCluster base class and are executed via transport client. Will be used especially for the REST tests once migrated to the standard randomized runner.
Added new httpAddresses method to ImmutableTestCluster to be able to retrieve the http addresses to connect to for the REST tests. Both versions will look inside the cluster to figure out which nodes are available for http calls and their addresses.
The external cluster is used as global cluster if the tests.cluster system property is available. The property needs to contain a comma separated list of available elasticsearch nodes that will be used to connect to the cluster (e.g. localhost:9300,localhost:9301).
Only a subset of the integration tests can currently be run successfully against the external cluster, for more precision the ones that don't modify the cluster layout (don't require cluster() functionalities but rely only on immutableCluster()). Also at least two data nodes are required otherwise the ensureGreen calls cannot succeed.

We have had a couple of bugs because of the use of these methods without paying
attention that it might return a negative value when provided with MIN_VALUE.
There is one common and legitimate usage of this method in order to perform
a modulo operation which would always return a positive number. This use-case
has been extracted to MathUtils.mod.

As documented in systemd's manual pages tmpfiles.d(5) and systemd.unit(5),
a package should install its default configuration in /usr/lib, which can
be overriden by system administrators in /etc.
New locations in the rpm:
/usr/lib/systemd/system/elasticsearch.service
/usr/lib/tmpfiles.d/elasticsearch.conf
When building elasticsearch, we now require to use java 1.7.
Maven will check that before compiling any class. If Java version is incorrect, you will get the following message:
```
[WARNING] Rule 0: org.apache.maven.plugins.enforcer.RequireJavaVersion failed with message:
Detected JDK Version: 1.6.0-65 is not in the allowed range [1.7,).
```
Closes#5428.
We have the default QueryWrapperFilter as well as our custom one while
our wrapper is explicitly marked as no_cache such that it will never
be included in a cache. This was not consistenly used and caused several
problems during tests where p/c related queries were used as filters
and ended up in the cache. This commit adds the QueryWrapperFilter
ctor to the forbidden APIs to enforce the query instance checks.
Note that the standard `atLeast` implementation has now Integer.MAX_VALUE as upper bound, thus it behaves differently from what we expect in our tests, as we never expect the upper bound to be that high.
Added our own `atLeast` to `AbstractRandomizedTest` so that it has the expected behaviour with a reasonable upper bound.
See https://github.com/carrotsearch/randomizedtesting/issues/131
Lucene's RamUsageEstimator.sizeOf(Object) is to expensive.
Query size estimation will be enabled when a cheaper way of query size estimation can be found.
Closes#5372

Today, even though our merge policy doesn't return new merge specs on SEGMENT_FLUSH, merge on the scheduler is still called on flush time, and can cause merges to stall indexing during merges. Both for the concurrent merge scheduler (the default) and the serial merge scheduler. This behavior become worse when throttling kicks in (today at 20mb per sec).
In order to solve it (outside of Lucene for now), we wrap the merge scheduler with an EnableMergeScheduler, where, on the thread level, using a thread local, the call to merge can be enabled/disabled.
A Merges helper class is added where all explicit merges operations should go through. If the scheduler is the enabled one, it will enable merges before calling the relevant explicit method call. In order to make sure Merges is the only class that calls the explicit merge calls, the IW variant of them is added to the forbidden APIs list.

Adds support for storing mustache based query templates that can later be filled
with query parameter values at execution time. Templates may be both quoted,
non-quoted and referencing templates stored in config/scripts/*.mustache by file
name.
See docs/reference/query-dsl/queries/template-query.asciidoc for templating
examples.
Implementation detail: mustache itself is being shaded as it depends directly on
guava - so having it marked optional but included in the final distribution
raises chances of version conflicts downstream.
Fixes#4879
This upgrade includes a fix for RAM estimation on IndexReader
that allows to expose the amount of used bytes per segment now
as a setting in Elasticsearch. (LUCENE-5373)
Additionally this bugfix release contained a small fix for highlighting
that was already ported to Elasticsearch when reported (LUCENE-5361)
Closes#4897
We currently run always with SecurityManager installed. To make sure we
work also without we should randomly swap it out ie. run without the
security manager.
We currently pull in the lucene-expression module that is referenced
by lucene-suggest. Yet, we don't make use of this dependency at all
and it pulls in a bunch of unshaded libs like `antlr` and `asm` which
are pretty common in other projects. We should exclude this
dependency since we don't use it at all and it causes problems
when Elasticsearch is used as a node client. (see #4858)
If we mark the dependency as provided it won't be included in the
distribution.

Refactor cache recycling so that it only caches large arrays (pages) that can
later be used to build more complex data-structures such as hash tables.
- QueueRecycler now takes a limit like other non-trivial recyclers.
- New PageCacheRecycler (inspired of CacheRecycler) has the ability to cache
byte[], int[], long[], double[] or Object[] arrays using a fixed amount of
memory (either globally or per-thread depending on the Recycler impl, eg.
queue is global while thread_local is per-thread).
- Paged arrays in o.e.common.util can now optionally take a PageCacheRecycler
to reuse existing pages.
- All aggregators' data-structures now use PageCacheRecycler:
- for all arrays (counts, mins, maxes, ...)
- LongHash can now take a PageCacheRecycler
- there is a new BytesRefHash (inspired from Lucene but quite different,
still; for instance it cheats on BytesRef comparisons by using Unsafe)
that also takes a PageCacheRecycler
Close#4557
Test can be run with `-Dtests.assertion.disabled=org.elasticsearch`
to run the tests without assertions to make sure assertions
don't hide any assignements etc. that introduce bugs in production.
