Christoph Büscher dfc0496fc0 Add warning to settings documentation about setting number_of_replicas on a closed index
Issue #9566 raises the point that setting the number of shards on a closed index can lead to this index not beeing able to open again. This change in documentation is ment to warn the user about this issue.

Ryan Ernst c6968883a7 Mappings: Remove support for new indexes using path setting in

Adrien Grand 95f46f1212 Docs: Use the new experimental annotation.
We now have a very useful annotation to mark features or parameters as
experimental. Let's use it! This commit replaces some custom text warnings with
this annotation and adds this annotation to some existing features/parameters:
 - inner_hits (unreleased yet)
 - terminate_after (released in 1.4)
 - per-bucket doc count errors in the terms agg (released in 1.4)

I also tagged with this annotation settings which should either be not needed
(like the ability to evict entries from the filter cache based on time) or that
are too deep into the way that Elasticsearch works like the Directory
implementation or merge settings.

Simon Willnauer 0c5599e1d1 [ENGINE] Remove full flush / FlushType.NEW_WRITER
The `full` option and `FlushType.NEW_WRITER` only exists to allow
realtime changes to two settings (`index.codec` and `index.concurrency`).
Those settings are very expert and don't really need to be updateable
in realtime.

Michael McCandless b9358ccca8 Core: switch to auto IO throttle for merges
This adds a new boolean (index.merge.scheduler.auto_throttle) dynamic
setting, default true (matching Lucene), to adaptively set the IO rate
limit for merges over time.

This is more flexible than the previous fixed rate throttling because
it responds depending on the incoming merge rate, so search-heavy
applications that are not doing much indexing will see merges heavily
throttled while indexing-heavy cases will lighten the throttle so
merges can keep up within incoming indexing.

The fixed rate throttling is still available as a fallback if things
go horribly wrong.

Ryan Ernst f7f99b8dbf Stats: Added verbose option to segments api, with full ram tree as first

This commit adds a verbose flag to the _segments api.  Currently the

Zachary Tong f5b2dfd052 Aliases: Throw exception if index is null or missing when creating an alias
Fixes a bug where alias creation would allow `null` for index name, which thereby
applied the alias to _all_ indices.  This patch makes the validator throw an
exception if the index is null.

```bash
POST /_aliases
{
   "actions": [
      {
         "add": {
            "alias": "empty-alias",
            "index": null
         }
      }
   ]
}
```
```json
{
   "error": "ActionRequestValidationException[Validation Failed: 1: Alias action [add]: [index] may not be null;]",
   "status": 400
}
```

The reason this bug wasn't caught by the existing tests is because
the old test for nullness only validated against a cluster which had
zero indices.  The null index is translated into "_all", and since
there are no indices, this fails because the index doesn't exist.
 So the test passes.

However, as soon as you add an index, "_all" resolves and you get the
situation described in the original bug report:  null index is
accepted by the alias, resolves to "_all" and gets applied to everything.

The REST tests, otoh, explicitly tested this bug as a real feature and therefore
passed.  The REST tests were modified to change this behavior.

Fixes #7863

Simon Willnauer d5c0a49620 [ROUTING] Add rebalance enabled allocation decider
This commit adds the ability to enable / disable relocations
on an entire cluster or on individual indices for either:

 * `primaries` - only primaries can rebalance
 * `replica` - only replicas can rebalance
 * `all` - everything can rebalance (default)
 * `none` - all rebalances are disabled

similar to the allocation enable / disable functionality.

Colin Goodheart-Smithe 8238388bad [DOCS] clarification of breaking changes to 1.4 due to GET index API 2014-09-11 15:04:04 +01:00
Colin Goodheart-Smithe 5fe782b784 Indices API: Added GET Index API
Returns information about settings, aliases, warmers, and mappings. Basically returns the IndexMetadata. This new endpoint replaces the /{index}/_alias|_aliases|_mapping|_mappings|_settings|_warmer|_warmers and /_alias|_aliases|_mapping|_mappings|_settings|_warmer|_warmers endpoints whilst maintaining the same response formats.  The only exception to this is on the /_alias|_aliases|_warmer|_warmers endpoint which will now return a section for 'aliases' or 'warmers' even if no aliases or warmers exist. This backwards compatibility change is documented in the reference docs.

Adrien Grand a242a63817 [DOCS] Remove the section about codecs.
This documentation was dangerous because it felt like it was possible to gain
substantial performance by just switching the codec of the index.

However, non-default codecs are dangerous to use since they are not supported
in terms of backward compatibility, and most improvements that they bring have
been folded into the default codec anyway (for example, the default codec
"pulses" postings lists that contain a single document).

Andrew Selden e2c8ff92ba Benchmark API
Add an API endpoint at /_bench for submitting, listing, and aborting
search benchmarks. This API can be used for timing search requests,
subject to various user-defined settings.

Benchmark results provide summary and detailed statistics on such
values as min, max, and mean time. Values are reported per-node so that
it is easy to spot outliers. Slow requests are also reported.

Long running benchmarks can be viewed with a GET request, or aborted
with a POST request.

Benchmark results are optionally stored in an index for subsequent
analysis.
