In order to return more information to the client, in case a TransportClient
can not connect to the cluster, this commit adds logging and also returns the
configured nodes in the NoNodeAvailableException
Also a minor bug has been fixed, which propagated exceptions wrong, so that an
invalid request was actually tried on every node, if a regular connection failure
on the first node had happened.
Closes#6376
Our REST backwards compatibility tests need to be able to disable client nodes within the TestCluster when running older tests that assume client nodes are not around.
Previously if the user provided a non-conforming string, it would blow up with
`java.lang.StringIndexOutOfBoundsException: String index out of range: -1`
which is not a *helpful* error message.
Also updated the documentation to make the possible setting values more clear.

A new "breadth_first" results collection mode allows upper branches of aggregation tree to be calculated and then pruned
to a smaller selection before advancing into executing collection on child branches.
Closes#6128
The put index template api supports the create parameter (defaults to false), which tells whether the template can replace an existing one with same name or not. Unified its behaviour between PUT and POST method, whereas the POST would previously force create to true.
Added create parameter to the rest spec (was missing before) and a REST test for create true scenario.
There is a pretty nasty bug in the lock factory we use that can cause
nodes to use the same data dir wiping each others data. Luckily this is
unlikely to happen if the nodes are running in different JVM which they
do unless they are embedded.

E.g. we use Unsafe in quite a few places and this generates lots of
warnings, which we now suppress using the undocumented
-XDignore.symbol.file command-line option to javac.
Closes#6423
The existing Note about the shorthand suggest syntax was poorly worded and confusing. Please check whether the way I've phrased it now is still correct as to what the shorthand form actually does and doesn't do: the original wording did not provide me enough information to be sure.
Thanks!
The _uid field wasn't available in a script despite it's always stored. Made it available and made available also _id and _type fields that are deducted from it.
Closes#6406
The versionMap holds all versions (keyed by _uid) for recently indexed
documents. Previously we only cleared it during flush, which can be
infrequent if the translog flush thresholds are high, and can cause
excessive heap usage especially for small documents.
Now we clear it during refresh which is usually more frequent
(e.g. once per second by default).
Closes#6379
The GeoBounds Aggregation is a new single bucket aggregation which outputs the coordinates of a bounding box containing all the points from all the documents passed to the aggregation as well as the doc count. Geobound Aggregation also use a wrap_logitude parameter which specifies whether the resulting bounding box is permitted to overlap the international date line. This option defaults to true.
This aggregation introduces the idea of MetricsAggregation which do not return double values and cannot be used for sorting. The existing MetricsAggregation has been renamed to NumericMetricsAggregation and is a subclass of MetricsAggregation. MetricsAggregations do not store doc counts and do not support child aggregations.
Closes#5634
This commit reverts the commit for issue #5900 introduced
in `1.2.0`. The unlimited translog size can cause memory pressure
on ES instances with low memory and high indexing load.
Closes#6377
Routing has been inadvertly changed in #5562 resulting in documents going to
different shards in 1.2. This is a terrible bug because an indexing request
would not necessarily go to the same shard anymore, potentially leading to
duplicates.
Close#6391
