Using '_cat/segments' or the indices segments api without matching any index
now returns empty result instead of throwing IndexMissingException.
Closes#9219
The percolate api doesn't parse the encoded body provided as `source` query string parameter, when percolating an existing document. Fixed and added REST test that would have caught this since we randomly use GET + encoded `source` param instead of GET + request body in our java runner (the perl runner does the same too).
Closes#9628
Until now, there was no possibility to expose infos about configured
transport profiles. This commit adds the ability to expose those
information in the TransportInfo class.
The channel was well as the netty pipeline handler now also contain
the profile they were configured for, as this information cannot be
extracted elsewhere.
In addition, each profile now can set its own publish host and port,
which might be needed in case of portforwarding or using docker.
Closes#9134
Adding missing support for the multi-index query parameters 'ignore_unavailable',
'allow_no_indices' and 'expand_wildcards' to '_cluster/state' API. These
parameters are supposed to be supported for APIs that work across multiple indices.
So far overwriting the default settings per REST call was not possible which is
fixed here.

Today we give the HTTP status back within the HTTP response itself and within the JSON response as well:
```sh
curl localhost:9200/
```
```js
{
"status" : 200,
"name" : "Red Wolf",
"version" : {
"number" : "2.0.0",
"build_hash" : "6837a61d8a646a2ac7dc8da1ab3c4ab85d60882d",
"build_timestamp" : "2014-08-19T13:55:56Z",
"build_snapshot" : true,
"lucene_version" : "4.9"
},
"tagline" : "You Know, for Search"
}
```
The header indicates to how many shard copies (primary and replicas shards) a write was supposed to go to, to how many
shard copies to write succeeded and potentially captures shard failures if writing into a replica shard fails.
For async writes it also includes the number of shards a write is still pending.
Closes#7994
This fix ensures that calls to the GET alias/mappings/settings/warmers APIs return the aliases/mappings/settings/warmers object even if there is no content within them.. This make them consistent with the GET Index API docs and the breaking changes in 1.4 docs
Closes#9148
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.
Closes#7480
Adds a `ignore_like` parameter to the MLT Query, which simply tells the
algorithm to skip all the terms from the given documents. This could be useful
in order to better guide nearest neighbor search by telling the algorithm to
never explore the space spanned by the given `ignore_like` docs. In essence we
are interested about the characteristic of a given item, but not of the ones
provided by `ignore_like`, thereby forcing the algorithm to go deeper in its
selection of terms. Note that this is different than simply performing a must
not boolean query on the unliked items. The syntax is exactly the same as the
`like` parameter.
Closes#8674
Today, Elasticsearch has a separate merge thread pool checking once
per second (by default) if any merges are necessary, but this is no
longer necessary since we can and do now tell Lucene's
ConcurrentMergeScheduler never to "hard pause" threads when merges
fall behind, since we do our own index throttling.
This change goes back to letting Lucene launch merges as needed, and
removes these two expert settings:
index.merge.force_async_merge
index.merge.async_interval
Now merges kick off immediately instead of waiting up to 1 second
before running.
Closes#8643
We speak of the term vectors of a document, where each field has an associated
stored term vector. Since by default we are requesting all the term vectors of
a document, the HTTP request endpoint should rather be called `_termvectors`
instead of `_termvector`. The usage of `_termvector` is now deprecated, as
well as the transport client call to termVector and prepareTermVector.
Closes#8484
Fixed behaviour where two representations of the default index analyzer weren't being treated as equivalent. Added REST test to confirm fix.
Closes#2716
If a shard (e.g. replica) gets initialized after we indexed the document it gets refreshed internally and we find the doc and its term_vectors, thus the test fails
We currently use the djb2 hash function in order to compute the shard a
document should go to. Unfortunately this hash function is not very
sophisticated and you can sometimes hit adversarial cases, such as numeric ids
on 33 shards.
Murmur3 generates hashes with a better distribution, which should avoid the
adversarial cases.
Here are some examples of how 100000 incremental ids are distributed to shards
using either djb2 or murmur3.
5 shards:
Murmur3: [19933, 19964, 19940, 20030, 20133]
DJB: [20000, 20000, 20000, 20000, 20000]
3 shards:
Murmur3: [33185, 33347, 33468]
DJB: [30100, 30000, 39900]
33 shards:
Murmur3: [2999, 3096, 2930, 2986, 3070, 3093, 3023, 3052, 3112, 2940, 3036, 2985, 3031, 3048, 3127, 2961, 2901, 3105, 3041, 3130, 3013, 3035, 3031, 3019, 3008, 3022, 3111, 3086, 3016, 2996, 3075, 2945, 2977]
DJB: [0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 900, 900, 900, 900, 1000, 1000, 10000, 10000, 10000, 10000, 9100, 9100, 9100, 9100, 9000, 9000, 0, 0, 0, 0, 0, 0]
Even if djb2 looks ideal in some cases (5 shards), the fact that the
distribution of its hashes has some patterns can raise issues with some shard
counts (eg. 3, or even worse 33).
Some tests have been modified because they relied on implementation details of
the routing hash function.
Close#7954
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
Add source_node and target_node fields to the recovery cat API. Also fixed and updated the documentation which was not complete concerning fields names.
Closes#8041
Storing `_timestamp` by default means that under the default configuration, you
would have all the information you need in order to reindex into a different
index.

cat/nodes currently does not report any details related to file descriptors. This adds the current number in use, the maximum number available as well as their ratio (percentage) to cat/nodes as hidden-by-default metrics. In addition, this also adds current heap usage (as a non-percentage of ts max) and ram usage (as a non-percerntage of its max) to allow tools to provide more granularity.
Closes#7652
When asking for `GET /_cat/indices?v`, you can now retrieve closed indices in addition to opened ones.

Closes#7936.
By default term vectors are now realtime, as opposed to previously near
realtime. If they are not found in the index, they will be generated on the
fly. The document is fetched from the transaction log and treated as an
artificial document. One can set `realtime` parameter to `false` in order to
disable this functionality. This consequently makes the MLT query realtime in
fetching documents, as it previsouly used to be before switching from using
the multi get API to the mtv API.
Closes#7846
Previously, the only way to specify a document not present in the index was to
use `like_text`. This would usually lead to complex queries made of multiple
MLT queries per document field. This commit adds the ability to the MLT query
to directly specify documents not present in the index (artificial documents).
The syntax is similar to the Percolator API or to the Multi Term Vector API.
Closes#7725
This contains several cleanups to the indexed scripts.
Remove the unused FetchSourceContext from the Get request..
Add lang,_version,_id to the REST GET API.
Removes the routing from GetIndexedScriptRequest since the script index is a single shard that is replicated across all nodes.
Fix backward compatible template file reference
Before 1.3.0 on disk scripts could be referenced by requesting
````
_search/template
{
"template" : "ondiskscript"
}
````
This was broken in 1.3.0 by requiring
````
{
"template" :
{
"file" : "ondiskscript"
}
}
````
This commit restores the previous behavior.
Remove support for preference, realtime and refresh
These parameters don't make sense anymore for indexed scripts as we always force the preference to _local and
always refresh after a Put to the indexed scripts index.

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.
Closes#4069
By default the reroute API should return the new cluster state, excluding the metadata. It was however it was wrongly using an old parameter (filter_metadata) and thus failed to do so. This commits restores but wiring it to the correct `metric` parameter. We also add an enum representing the possible metrics, to avoid similar future mistakes.
Closes#7520Closes#7523
The get, put and delete indexed script apis map to get, index and delete api and internally create those corresponding requests. We need to make sure that the original headers are handed over to the new request by passing the original request in the constructor when creating the new one.
Also streamlined the support for version and version_type in the REST layer since the parameters were not consistently parsed and set to the internal java API requests.
Modified the REST delete template and delete script actions to make use of a client instead of using the `ScriptService` directly.
Closes#7569
The root endpoint returns basic information about this node, like it's name and ES version etc. The cluster name is an important information that belongs in that list.
Closes#7524
This change means that the default settings for expand_wildcards are only applied if the expand_wildcards parameter is not specified rather than being set upfront. It also adds the none and all options to the parameter to allow the user to specify no expansion and expansion to all indexes (equivalent to 'open,closed')
Closes#7258
Index, type and id were returned as part of the REST explain api response, but not through java api. That info was read out of the request, relying on the fact that the index would get overridden with the concrete one within that same request.
Closes#7201
In the case of inserts the UpdateHelper class will now allow the script used to apply updates to run on the upsert doc provided by clients. This allows the logic for managing the internal state of the data item to be managed by the script and is not reliant on clients performing the initialisation of data structures managed by the script.
Closes#7143
This change allow elasticsearch users to store scripts and templates in an index for use at search time.
Scripts/Templates are stored in the .scripts index. The type of the events is set to the script language.
Templates use the mustache language so their type is be "mustache".
Adds the concept of a script type to calls to the ScriptService types are INDEXED,INLINE,FILE.
If a script type of INDEXED is supplied the script will be attempted to be loaded from the indexed, FILE will
look in the file cache and INLINE will treat the supplied script argument as the literal script.
REST endpoints are provided to do CRUD operations as is a java client library.
All query dsl points have been upgraded to allow passing in of explicit script ids and script file names.
Backwards compatible behavior has been preserved so this shouldn't break any existing querys that expect to
pass in a filename as the script/template name. The ScriptService will check the disk cache before parsing the
script.
Closes#5921#5637#5484
Concrete indices is now called multiple times when needed instead of changing what's inside the incoming request with the concrete indices. Ideally we want to keep the original aliases or indices or wildcard expressions in the request.
Also made sure that the check blocks is done against the concrete indices, which wasn't the case for delete index, delete mapping, open index, close index, types exists and indices exists.

Commit fbd7c9aa5d introduced a regression that caused
the min_doc_count to be equal to the number of documents in the

Bugs:
* "groups" and "types" were being ignored
* "completion_fields" as wildcards were not being resolved to fieldnames
Enhancements:

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.
Adding the second index might cause relocation of existing shards depending on the number of nodes available, let's wait for relocation to be finished before going ahead and checking the cat shards outpu
Until now all version types have officially required the version to be a positive long number. Despite of this has being documented, ES versions <=1.0 did not enforce it when using the `external` version type. As a result people have succesfully indexed documents with 0 as a version. In 1.1. we introduced validation checks on incoming version values and causing indexing request to fail if the version was set to 0. While this is strictly speaking OK, we effectively have a situation where data already indexed does not match the version invariant.
To be lenient and adhere to spirit of our data backward compatibility policy, we have decided to allow 0 as a valid external version type. This is somewhat complicated as 0 is also the internal value of `MATCH_ANY`, which indicates requests should succeed regardles off the current doc version. To keep things simple, this commit changes the internal value of `MATCH_ANY` to `-3` for all version types.
Since we're doing this in a minor release (and because versions are stored in the transaction log), the default `internal` version type still accepts 0 as a `MATCH_ANY` value. This is not a problem for other version types as `MATCH_ANY` doesn't make sense in that context.
Closes#5662
Made sure that a match_all query is used when no query is specified and ensure no NPE is thrown either.
Also used the same code path as the search api to ensure that alias filters are taken into account, same for type filters.
Closes#6111Closes#6112Closes#6116
In our REST tests we already have support for features and skip sections that allow to skip tests if a feature is not supported.
We can then add a skip section based on the benchmark feature to the benchmark tests and execute them only when they are supported, knowing that they need at least a node with node.bench settings within the cluster. We can check that this requirement is met by calling the nodes info api.
This way we can dynamically decide whether to execute those tests or not and we don't need to have a node.bench around all the time. In fact, given that the REST tests use the GLOBAL cluster, we want to be able to randomize settings as much as possible and run tests against default settings as well. Also, this mechanism can be easily supported by the external cluster implementation that is used during the release process.
Introduced ability to disable benchmark nodes which is needed by BenchmarkNegativeTest.
This fixes a stack overflow in the test for the _cat/recovery API.
The regular expression that tests the response body was modified to
handle large responses properly.
The rest test for _cat/allocation was failing due to a regular
expression not accounting for space-padded right-justified text.
Also added Improvements to regular expressions to be smarter about optional values
and to use '+' instead of '*' where applicable.
A bad/non-existing scroll ID used to return a 200, however a 404 might be more useful.
Also, this PR returns the right Exception (SearchContextMissingException) in the Java API.
Additionally: Added StatusToXContent interface and RestStatusToXContentListener listener, so
the appropriate RestStatus can be returned
