PR #8978 included 4 unnecessary enumeration values ('cw', 'clockwise', 'ccw', 'counterclockwise'). Since the ShapeBuilder.parse method handles these as strings and maps them to LEFT and RIGHT enumerators, respectively, their enumeration counterpart is unnecessary. This minor change adds 4 static convenience variables (COUNTER_CLOCKWISE, CLOCKWISE, CCW, CW) for purposes of the API and removes the unnecessary values from the Orientation Enum.

This feature adds an optional orientation parameter to the GeoJSON document and geo_shape mapping enabling users to explicitly define how they want Elasticsearch to interpret vertex ordering. The default uses the right-hand rule (counterclockwise for outer ring, clockwise for inner ring) complying with OGC Simple Feature Access standards. The parameter can be explicitly specified for an entire index using the geo_shape mapping by adding "orientation":{"left"|"right"|"cw"|"ccw"|"clockwise"|"counterclockwise"} and/or overridden on each insert by adding the same parameter to the GeoJSON document.

When I originally wrote the transform feature I didn't think that the
XContentType of the reencoded source mattered. It actually matters because
payloads for the completion suggester are stored and returned exactly
as encoded by this XContentType.
This revision changes the transform feature from always reencoding with smile
to always reencoding with the provided XContentType to support the completion
suggester.

This commit adds the support for the Ctrl-Close event on Windows using native system calls. This way, it is possible to catch the Ctrl-Close event sent by a 'taskill /pid' command (or when the user closes the console window where elasticsearch.bat was started) and gracefully close the node. Before this commit, the node was simply killed on taskkill/window closing.
There was a race condition in the test in the case where the nodes fault detection would manage to send and initial ping, followed by 2 attempts before the target service was disconnected.
RecoveryTarget initiates the recovery by sending a start recovery request to the source node and then waits for the recovery to complete. During recovery cancellation, we interrupt the thread so it will wake up and clean the recovery. Depending on timing, this can leave an unneeded interrupted thread status causing future IO commands to fail unneeded.
RecoverySource already had a handy utility called CancellableThreads. This extracts it to a top level class, and uses it in RecoveryTarget as well.
Closes#9000
Up to now, all filters could be cached using the `_cache` flag that could be
set to `true` or `false` and the default was set depending on the type of the
`filter`. For instance, `script` filters are not cached by default while
`terms` are. For some filters, the default is more complicated and eg. date
range filters are cached unless they use `now` in a non-rounded fashion.
This commit adds a 3rd option called `auto`, which becomes the default for
all filters. So for all filters a cache wrapper will be returned, and the
decision will be made at caching time, per-segment. Here is the default logic:
- if there is already a cache entry for this filter in the current segment,
then return the cache entry.
- else if the doc id set cannot iterate (eg. script filter) then do not cache.
- else if the doc id set is already cacheable and it has been used twice or
more in the last 1000 filters then cache it.
- else if the filter is costly (eg. multi-term) and has been used twice or more
in the last 1000 filters then cache it.
- else if the doc id set is not cacheable and it has been used 5 times or more
in the last 1000 filters, then load it into a cacheable set and cache it.
- else return the uncached set.
So for instance geo-distance filters and script filters are going to use this
new default and are not going to be cached because of their iterators.
Similarly, date range filters are going to use this default all the time, but
it is very unlikely that those that use `now` in a not rounded fashion will get
reused so in practice they won't be cached.
`terms`, `range`, ... filters produce cacheable doc id sets with good iterators
so they will be cached as soon as they have been used twice.
Filters that don't produce cacheable doc id sets such as the `term` filter will
need to be used 5 times before being cached. This ensures that we don't spend
CPU iterating over all documents matching such filters unless we have good
evidence of reuse.
One last interesting point about this change is that it also applies to compound
filters. So if you keep on repeating the same `bool` filter with the same
underlying clauses, it will be cached on its own while up to now it used to
never be cached by default.
`_cache: true` has been changed to only cache on large segments, in order to not
pollute the cache since small segments should not be the bottleneck anyway.
However `_cache: false` still has the same semantics.

We use PlainTransportFuture as a future for our transport calls. If someone blocks on it and it is interrupted, we throw an ElasticsearchIllegalStateException. We should not set Thread.currentThread().interrupt(); in this case because we already communicate the interrupt through an exception.

This commit makes histogram reduction a bit cleaner by expecting buckets
returned from shards to be sorted by key and merging them on-the-fly on the
coordinating node using a priority queue.

This commit adds support for version and version_type to the Term Vectors API.
This could be useful in the following case whereby the user gets a document
and later wants to generate its TVs. With version, this would ensure that only
the TVs of that particular document are generated, and error out if the
document has been updated in between.

When a node tries to join a master, the master may not yet be ready to accept the join request. In such cases we retry sending the join request up to 3 times before going back to ping. To detect this the current logic uses ExceptionsHelper.unwrapCause(t) to unwrap the incoming RemoteTransportException and inspect it's source, looking for ElasticsearchIllegalStateException. However, local ElasticsearchIllegalStateException can also be thrown when the join process should be cancelled (i.e., node shut down). In this case we shouldn't retry.
This commit adds an explicit NotMasterException to indicate the remote node is not a master. A similarly named exception (but meaning something else) in the master fault detection code was given a better name. Also clean up some other exceptions while at it.
Closes#8972
This allows specifying the path an index will be at.
`index.data_path` is specified in the settings when creating an index,
and can not be dynamically changed.
An example request would look like:
POST /myindex
{
"settings": {
"number_of_shards": 2,
"data_path": "/tmp/myindex"
}
}
And would put data in /tmp/myindex/0/index/0 and /tmp/myindex/0/index/1
Since this can be used to write data to arbitrary locations on disk, it
requires enabling the `node.enable_custom_paths` setting in
elasticsearch.yml on all nodes.
This commit adds the logic necessary for supporting polygon vertex ordering per OGC standards. Exterior rings will be treated in ccw (right-handed rule) and interior rings will be treated in cw (left-handed rule). This feature change supports polygons that cross the dateline, and those that span the globe/map. The unit tests have been updated and corrected to test various situations. Greater test coverage will be provided in future commits.
Addresses #8672
This feature branch implements OGC compliance for Polygon/Multi-polygon. That is, vertex order for the exterior ring follows the right-hand rule (ccw) and all holes follow the left-hand rule (cw). While GeoJSON imposes no restrictions, a user that wants to specify a complex poly across the dateline must do so in compliance with the OGC spec, otherwise a polygon that spans the globe will be assumed.
Reference issue #8672
Fix orientation of outer and inner ring for polygon with holes. Updated unit tests. Bug exists in boundary condition on negative side of dateline.
This provides a fix to issue #7644. A new Stats object must be created, and
not a reference to the retrieved stats, before we can add stats to it.
Otherwise, we would keep on adding to the same object on subsequent calls to
IndicesStatsResponse#getPrimaries() or IndicesStatsResponse#getTotal().
Closes#7644 and #8950
The "compressed" format was removed, so this caused warnings in the log
like:
```
[WARN ][index.fielddata ] [node_0] [test] failed to find format
[compressed] for field [test-num], will use default
```
Now that we do not automatically call .cleanUp() when clearing the field
data cache, we need to call it after the cache clear in
