We already force a refresh in index/create ops, to clear version map
when it's using too much RAM, but we were failing to do this for
deletes, so an app that does tons of deletes with no indexing, and has
set refresh_interval to -1, would have version map using unbounded
RAM.
Closes#10312
After processing mapping updates from the master, we compare the resulting binary representation of them and compare it the one cluster state has. If different, we send a refresh mapping request to master, asking it to reparse the mapping and serialize them again. This mechanism is used to update the mapping after a format change caused by a version upgrade.
The very same process can also be triggered when an old master leaves the cluster, triggering a local cluster state update. If that update contains old mapping format, the local node will again signal the need to refresh, but this time there is no master to accept the request. Instead of failing (which we now do because of #10283, we should just skip the notification and wait for the next elected master to publish a new mapping (triggering another refresh if needed).
Closes#10311
Even if there is a background thread that periodically closes search contexts
that seem unused (every minute by default), it is important to close search
contexts as soon as possible in order to not keep unnecessary open files or
to prevent segments from being deleted.
This check would help ensure that refactorings of the SearchContext management
like #9296 are correct.
When the index service (which holds shards) fails to be created as a result of a shard being allocated on a node, we should fail the relevant shard, otherwise, it will remain stuck.
Same goes when there is a failure to process updated mappings form the master.
Note, both failures typically happen when the node is misconfigured (i.e. missing plugins, ...), since they get created and processed on the master node before being published.

Doc values significantly reduced heap usage, which results in faster
GCs. This change makes the default for doc values dynamic: any
field that is indexed but not analyzed now has doc values. This only
affects fields on indexes created with 2.0+.
closes#8312closes#10209
The local DocumentMapper is updated while parsing and dynamic fields are added before
parsing has finished. If parsing fails after a dynamic field has been added already
then the field was not added to the cluster state but was present in the local mapper of this
node. New documents with the same field would not necessarily cause an update either and
after restarting the node the mapping for these fields were lost. Instead the new fields
should always be updated.

We currently have a single bw comp test (FunctionScoreBackwardCompatibilityTests) that requires inline scripts on.
After introducing fine-grained script settings, we moved the internal cluster to use the newer settings, but they are not supported by older nodes started as part of the bw comp tests. Moved script settings out of the default settings, so they won't be part of the ordinary settings when running bw comp tests.
Added logic in FunctionScoreBackwardCompatibilityTests to enable dynamic scripts using the proper setting, depending on the version of the node.
Allow to on/off scripting based on their source (where they get loaded from), the operation that executes them and their language.
The settings cover the following combinations:
- mode: on, off, sandbox
- source: indexed, dynamic, file
- engine: groovy, expressions, mustache, etc
- operation: update, search, aggs, mapping
The following settings are supported for every engine:
script.engine.groovy.indexed.update: sandbox/on/off
script.engine.groovy.indexed.search: sandbox/on/off
script.engine.groovy.indexed.aggs: sandbox/on/off
script.engine.groovy.indexed.mapping: sandbox/on/off
script.engine.groovy.dynamic.update: sandbox/on/off
script.engine.groovy.dynamic.search: sandbox/on/off
script.engine.groovy.dynamic.aggs: sandbox/on/off
script.engine.groovy.dynamic.mapping: sandbox/on/off
script.engine.groovy.file.update: sandbox/on/off
script.engine.groovy.file.search: sandbox/on/off
script.engine.groovy.file.aggs: sandbox/on/off
script.engine.groovy.file.mapping: sandbox/on/off
For ease of use, the following more generic settings are supported too:
script.indexed: sandbox/on/off
script.dynamic: sandbox/on/off
script.file: sandbox/on/off
script.update: sandbox/on/off
script.search: sandbox/on/off
script.aggs: sandbox/on/off
script.mapping: sandbox/on/off
These will be used to calculate the more specific settings, using the stricter setting of each combination. Operation based settings have precedence over conflicting source based ones.
Note that the `mustache` engine is affected by generic settings applied to any language, while native scripts aren't as they are static by definition.
Also, the previous `script.disable_dynamic` setting can now be deprecated.

In #9893, an enabled flag was added for _field_names. However,
backcompat for indexes created before 1.3.0 (when _field_names
was added) was lost. This change corrects the mapper
to always be disabled when used with older indexes that
cannot have _field_names.
closes#10268
Deleting a type from an index is inherently dangerous because
the type can be recreated with new mappings which may conflict
with existing segments still using the old mappings. This
removes the ability to delete a type (similar to how deleting
fields within a type is not allowed, for the same reason).

This adds the Explanation to the explain score again. It is needed
because the explanation of script functions will otherwise not contain
an explanation of _score if boost mode is set to replace.
closes#9826
Fail merge if validate_lat or validate_lon values are not equal. This will prevent inconsistencies between geo_points in a merged index, and parse exceptions for bounding_box and distance filters.
Also merged separate GeoPoint test classes into a single GeoPointFieldMapperTest to be consistent with GeoShapeFieldMapperTests.

* add compiler workarounds for JDK bug JI-9019884
* remove permgen specification during tests (this results in an error on java 9)
* fix threadpool grow/shrink to call methods in the right order (this results in IAE with java 9)
Documentation states false as the default for "validate", "validate_lon", and "validate_lat" leading to confusion as described in issue #9539. This simple fix corrects the documentation and communicates that these fields will be deprecated and removed in upcoming versions.
closes#9539
