This commit moves template support out of the Search API to its own dedicated Search Template API in the lang-mustache module. It provides a new SearchTemplateAction that can be used to render templates before it gets delegated to the usual Search API. The current REST endpoint are identical, but the Render Search Template endpoint now uses the same Search Template API with a new "simulate" option. When this option is enabled, the Search Template API only renders template and returns immediatly, without executing the search.
Closes#17906
There are secondary issues with async shard fetch going out to nodes before they have a cluster state published to them that need to be solved first. For example:
- async fetch uses transport node action that resolves nodes based on the cluster state (but it's not yet exposed by ClusterService since we inline the reroute)
- after disruption nodes will respond with an allocated shard (they didn't clean up their shards yet) which throws of decisions master side.
- nodes deed the index meta data in question but they may not have if they didn't recieve the latest CS
If a plugin declares `onModule(SomethingThatIsntAModule)` then refuse
to start. Before this commit we just logged a warning that flies by in
the console and is easy to miss. You can't miss refusing to start!
This commit removes duplicated methods for reading byte arrays in
StreamInput. One method would read a byte array by repeatedly calling
StreamInput#readByte in a loop, and the other would just call
StreamInput#readBytes. In this commit, we remove the former.

`stored_fields` parameter will no longer try to retrieve fields from the _source but will only return stored fields.
`fields` will throw an exception if the user uses it.
Add `docvalue_fields` as an adjunct to `fielddata_fields` which is deprecated. `docvalue_fields` will try to load the value from the docvalue and fallback to fielddata cache if docvalues are not enabled on that field.
Closes#18943
This commit refactors InternalEngine#innerIndex and
InternalEngine#innerDelete to collapse some common logic into a single
method. This has the advantage that it shrinks the bytecode size of
InternalEngine#innerIndex so that it can be inlined.
Makes ScriptModule just a plain class that manages building the
ScriptSettings and ScriptService from plugins. When we *need*
to bind ScriptService with guice we bind it in a lambda.
- fix it so that processors with the `ignore_failure` option do not
record their exception in the response
- add more tests to make empty `on_failure`. This now throws an
exception
Today we only throw random exceptions on the translog writer. This commit
extends it to also throw exceptions during checkpoint writing etc to test
if the correct flags are provided to open method etc.
This makes this sequence:
```
curl -XDELETE localhost:9200/source,dest?pretty
for i in $( seq 1 100 ); do
curl -XPOST localhost:9200/source/test -d'{"test": "test"}'; echo
done
curl localhost:9200/_refresh?pretty
curl -XPOST 'localhost:9200/_reindex?pretty&wait_for_completion=false' -d'{
"source": {
"index": "source"
},
"dest": {
"index": "dest"
}
}'
curl 'localhost:9200/_tasks/Jsyd6d9wSRW-O-NiiKbPcQ:237?wait_for_completion&pretty'
```
Return task *AND* the response to the user.
This also renames "result" to "response" in the persisted task info
to line it up with how we name the objects in Elasticsearch.
This commit modifies reading the Elasticsearch jar manifest via the URL
instead of converting the URL to an NIO path for increased portability.

The default similarity was set to `classic` which refers to TFIDF and has not been moved after the upgrade to Lucene 6.
Though moving to BM25 could have some downside for queries that relies on coordination factor (match_query, multi_match_query) ?

The MMapDirectory has a switch that allows the content of files to be loaded
into the filesystem cache upon opening. This commit exposes it with the new
`index.store.pre_load` setting.
Today we only emit that the setting wasn't found unless we have
some DYM suggestions. Yet, if a setting is not found at all and there
are no suggestions due to typos it's likely a removed setting or the plugin
that is supposed to be configured is not installed.
This commit adds some info text to the exception to help the user debugging
the problem before opening bugreports.
Instead of emitting:
`unknown setting [foo.bar]`
we now emit:
`unknown setting [foo.bar] please check the migration guide for removed settings and ensure that the plugin you are configuring is installed`

If someone sets `index.shard.check_on_startup`, indexing start up time can be slow (by design, it diligently goes and checks all data). If for some reason the shard is closed in that time, the store ref is kept around and prevents a new shard copy to be allocated to this node via the shard level locks. This is especially tricky if the shard is close due to a cancelled recovery which may re-restart soon.
This commit adds a cancellable threads instance to each IndexShard and perform index checking underneath it, so it can be cancelled on close.
