Retrieving distributed DF for TermVectors is beside it's esotheric justification
a very slow process and can cause serious load on the cluster. We also don't have nearly
enough testing for this stuff and given the complexity we should remove it rather than carrying it
around.
When there is an exception thrown during pipeline creation within
Rest calls (in put pipeline, and simulate) We now return a structured
error response to the user with details around which processor's
configuration is the cause of the issue, or which configuration property
is misconfigured, etc.
We used to have a disabled test around cluster put settings as it left cluster settings behind without a way to remove them. That has been in fixed in the cluster put settings api, so the test can be re-enabled.
The search_after parameter provides a way to efficiently paginate from one page to the next. This parameter accepts an array of sort values, those values are then used by the searcher to sort the top hits from the first document that is greater to the sort values.
This parameter must be used in conjunction with the sort parameter, it must contain exactly the same number of values than the number of fields to sort on.
NOTE: A field with one unique value per document should be used as the last element of the sort specification. Otherwise the sort order for documents that have the same sort values would be undefined. The recommended way is to use the field `_uuid` which is certain to contain one unique value for each document.
Fixes#8192
Merge feature/ingest branch into master branch.
This adds the ingest feature to ES that allows to preprocess document before indexing on an ingest node.
By default a node is an ingest node. Documents are preprocessed via a pipeline. A pipeline consists
out of one or more processors Each processor makes one or more modifications to a document processed.
There are many types of processors available out-of-the-box that are designed to make a specific change to a document being processed. In a cluster many pipeline can be configured via dedicated pipeline APIs. An new option on the bulk
and index APIs allows to control what pipeline is picked for preprocessing. If no pipeline is specified then the ingest
feature is skipped and no preprocessing takes place.
Site plugins used to be used for things like kibana and marvel, but
there is no longer a need since kibana (and marvel as a kibana plugin)
uses node.js. This change removes site plugins, as well as the flag for
jvm plugins. Now all plugins are jvm plugins.
This change affects get alias, get aliases as well as cat aliases. They all return closed indices too by default. get alias and get aliases also allow to return open indices only through the `expand_wildcards` option (set it to `open`).
Closes#14982
Warmers are now barely useful and will be removed in 3.0. Note that this only
removes the warmer API and query-based warmers. We still have warmers internally
for eg. global ordinals.
Close#15607
* Added percolator field mapper that extracts the query terms and indexes these terms with the percolator query.
* At percolate time these extracted terms are used to query percolator queries that are like to be evaluated. This can significantly cut down the time it takes to percolate. Whereas before all percolator queries were evaluated if they matches with the document being percolated.
* Changes made to percolator queries are no longer immediately visible, a refresh needs to happen before the changes are visible.
* By default the percolate api only returns upto 10 matches instead of returning all matching percolator queries.
* Made percolate more modular, so that it is easier to add unit tests.
* Added unit tests for the percolator.

Adds task manager class and enables all activities to register with the task manager. Currently, the immutable Transport*Activity class represents activity itself shared across all requests. This PR adds and an additional structure Task that keeps track of currently running requests and can be used to communicate with these requests using TransportTaskAction.

This adds the required changes/checks so that the build can run on
FreeBSD.
There are a few things that differ between FreeBSD and Linux:
- CPU probes return -1 for CPU usage
- `hot_threads` cannot be supported on FreeBSD
From OpenJDK's `os_bsd.cpp`:
```c++
bool os::is_thread_cpu_time_supported() {
#ifdef __APPLE__
return true;
#else
return false;
#endif
}
```
So this API now returns (for each FreeBSD node):
```
curl -s localhost:9200/_nodes/hot_threads
::: {Devil Hunter Gabriel}{q8OJnKCcQS6EB9fygU4R4g}{127.0.0.1}{127.0.0.1:9300}
hot_threads is not supported on FreeBSD
```
- multicast fails in native `join` method - known bug:
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=193246
Which causes:
```
1> Caused by: java.net.SocketException: Invalid argument
1> at java.net.PlainDatagramSocketImpl.join(Native Method)
1> at java.net.AbstractPlainDatagramSocketImpl.join(AbstractPlainDatagramSocketImpl.java:179)
1> at java.net.MulticastSocket.joinGroup(MulticastSocket.java:323)
1> at org.elasticsearch.plugin.discovery.multicast.MulticastChannel$Plain.buildMulticastSocket(MulticastChannel.java:309)
```
So these tests are skipped on FreeBSD.
Resolves#15562
Do not to load fields from _source when using the `fields` option.
Non stored (non existing) fields are ignored by the fields visitor when using the `fields` option.
Fixes#10783
Support * wildcard to retrieve stored fields when using the `fields` option.
Supported pattern styles are "xxx*", "*xxx", "*xxx*" and "xxx*yyy".
This adds support for arbitrary headers sent with each REST request, it
will allow us to test things like different xcontent-encoding (see
50_with_headers.yaml for what this looks like).
Headers are specified at the same level as `catch`, so a request would
look like:
```yaml
- do:
headers:
Content-Type: application/yaml
get:
index: test_1
type: _all
id: 1
```
This commit fixes a test bug in the cat shards REST test. In
particular, there was a race condition in the test that would cause the
test to sometimes fail. The race condition is that some of the shards
would go to state STARTED after the sync flush was issued. These shards
would (correctly) show up in the output as having state started but
without a sync_id. However, the expected output was written to only
look for shards that have state STARTED and a sync_id, or shards that
are still INITIALIZING or are UNASSIGNED and (of course) do not have a
sync_id. The best approach here is to just simplify the test.
The completion suggester provides auto-complete/search-as-you-type functionality.
This is a navigational feature to guide users to relevant results as they are typing, improving search precision.
It is not meant for spell correction or did-you-mean functionality like the term or phrase suggesters.
The completions are indexed as a weighted FST (finite state transducer) to provide fast Top N prefix-based
searches suitable for serving relevant results as a user types.
closes#10746
Similarly to what we did with the search api, we can now also move query parsing on the coordinating node for the validate query api. Given that the explain api is a single shard operation (compared to search which is instead a broadcast operation), this doesn't change a lot in how the api works internally. The main benefit is that we can simplify the java api by requiring a structured query object to be provided rather than a bytes array that will get parsed on the data node. Previously if you specified a QueryBuilder it would be serialized in json format and would get reparsed on the data node, while now it doesn't go through parsing anymore (as expected), given that after the query-refactoring we are able to properly stream queries natively. Note that the WrapperQueryBuilder can be used from the java api to provide a query as a string, in that case the actual parsing of the inner query will happen on the data node.
Relates to #10217Closes#14384
We have two types of parse methods for queries: one for the inner query, to be used once the parser is positioned within the query element, and one for the whole query source, including the query element that wraps the actual query.
With the search refactoring we ended up using the former in count, cat count and delete by query, whereas we should have used the former. It ends up working properly given that we have a registered (deprecated) query called "query", which used to allow to wrap a filter into a query, but this has the following downsides:
1) prevents us from removing the deprecated "query" query
2) we end up supporting a top level query that is not wrapped within a query element (pre 1.0 syntax iirc that shouldn't be supported anymore)
This commit finally removes the "query" query and fixes the related parsing bugs. We also had some tests that were providing queries in the wrong format, those have been fixed too.
Closes#13326Closes#14304
This adds an API for force merging lucene segments. The `/_optimize` API is now
deprecated and replaced by the `/_forcemerge` API, which has all the same flags
and action, just a different name.
Currently it's not possible to specify a timeout for nodes operations (such as node info, node stats, cluster stats and hot threads) via REST-based APIs.
The `_create` API is handy way to specify an index operation should only be done if the document doesn't exist. This is currently implemented in explicit code paths all the way down to the engine. However, conceptually this is no different than any other versioned operation - instead of requiring a document is on a specific version, we require it to be deleted (or non-existent). This PR removes Engine.Create in favor of a slight extension in the VersionType logic.
There are however a couple of side effects:
- DocumentAlreadyExistsException is removed and VersionConflictException is used instead (with an improved error message)
- Update will reject version parameters if the upsert option is used (it doesn't compute anyway).
- Translog.Create is also removed infavor of Translog.Index (that's OK because their binary format was the same, so we can just read Translog.Index of the translog file)
Closes#13955
This commit removes all the opaque bytes for extra_source and template_source.
Instead source and extra_source etc. are represented as SearchSourceBuilder which can
in-place be modified and is updated with the content of the request parameters.
Template Source is parsed and evaluated which in-turn replaces the actual source.
Adds a node attribute to all test runs and uses the attribute to test
`_cat/nodeattrs`.
Note that its quite possible create an impressively slow regex while doing
this and you have to be careful. See comment in commit for more if curious.
Closes#12558
detect_noop is pretty cheap and noop updates compartively expensive so this
feels like a sensible default.
Also had to do some testing and documentation around how _ttl works with
detect_noop.
Closes#11282
Conflicting mappings that were allowed before v2.0 can cause runaway shard failures on upgrade. This commit adds a check that prevents a cluster from starting if it contains such indices as well as restoring such indices from a snapshot into already running cluster.
Closes#11857
this change was added recently which uses default timezone for the creation
date on CAT endpoints. We should be consistent and use UTC across the board.
This commit adds #getDefaultTimzone() to forbidden API and fixes the REST tests.

Store information reports on which nodes shard copies exist, the shard
copy version, indicating how recent they are, and any exceptions
encountered while opening the shard index or from earlier engine failure.
closes#10952
Today we have a intermediate hierarchy for shard and index exceptions
which makes it hard to introduce generic exceptions like ResourceNotFoundException
intoduced in this commit. This commit breaks up the hierarchy by adding index and shard
as a special internal header that gets rendered for every exception that fills that header.
This commit removes dedicated exceptions like `IndexMissingException` or
`IndexShardMissingException` in favour of `ResourceNotFoundException`
This test asserts that the first recovery result is of type SNAPSHOT.
This assertion might not be true depending on the rendering order if
a replica is recovered quick enough. This commit disables replicas and
their recovery since it's not the purpose of this test.
This information was stored with the snapshot but wasn't available on the interface. Knowing the version of elasticsearch that created the snapshot can be useful to determine the minimal version of the cluster that is required in order to restore this snapshot.
Closes#11980
This commit adds support to retrieve fields when using the bulk update API. This functionality was previously available for the update API
but not for the bulk update API.
Closes#11527
Field stats index constraints allows to omit all field stats for indices that don't match with the constraint. An index
constraint can exclude indices' field stats based on the `min_value` and `max_value` statistic. This option is only
useful if the `level` option is set to `indices`.
For example index constraints can be useful to find out the min and max value of a particular property of your data in
a time based scenario. The following request only returns field stats for the `answer_count` property for indices
holding questions created in the year 2014:
curl -XPOST 'http://localhost:9200/_field_stats?level=indices' -d '{
"fields" : ["answer_count"] <1>
"index_constraints" : { <2>
"creation_date" : { <3>
"min_value" : { <4>
"gte" : "2014-01-01T00:00:00.000Z",
},
"max_value" : {
"lt" : "2015-01-01T00:00:00.000Z"
}
}
}
}'
Closes#11187
In order to be more consistent with what they do, the query cache has been
renamed to request cache and the filter cache has been renamed to query
cache.
A known issue is that package/logger names do no longer match settings names,
please speak up if you think this is an issue.
Here are the settings for which I kept backward compatibility. Note that they
are a bit different from what was discussed on #11569 but putting `cache` before
the name of what is cached has the benefit of making these settings consistent
with the fielddata cache whose size is configured by
`indices.fielddata.cache.size`:
* index.cache.query.enable -> index.requests.cache.enable
* indices.cache.query.size -> indices.requests.cache.size
* indices.cache.filter.size -> indices.queries.cache.size
Close#11569
This commit consolidates several abstractions on the shard level in
ordinary classes not managed by the shard level guice injector.
Several classes have been collapsed into IndexShard and IndexShardGatewayService
was cleaned up to be more lightweight and self-contained. It has also been moved into
the index.shard package and it's operation is renamed from recovery from "gateway" to recovery
from "store" or "shard_store".
Closes#11847
This is a follow up to #8143 and #6730 for _timestamp. It removes
support for `path`, as well as any field type settings, and
enables docvalues for _timestamp, for 2.0. Users who need to
adjust these settings can use a date field.
In order to get a quick overview using by simply checking the cluster state
and its corresponding cat API, the following two attributes have been added
to the cluster health response:
* task max waiting time, the time value of the first task of the
queue and how long it has been waiting
* active shards percent: The percentage of the number of shards that are in
initializing state
This makes the cluster health API handy to check, when a fully restarted
cluster is back up and running.
Closes#10805
The change makes rest-spec-api a project in the same way as we build dev-tools. it packages the tests and api in a bundle using the maven-remote-resources-plugin and uses the same plugin in the plugins and core pom to unpack the rest-api-spec into the target directory and references the rest tests there in the test resources.
The main stimulus for this change is that for those using Eclipse the current build does not work. After running `mvn eclipse:eclipse` the Eclipse IDE errors because the rest-api-spec is outside of the project scope, meaning that every time the command is run (required whenever any dependencies change), the class path of all the projects has to be manually fixed.
