this is a minor cleanup that detaches `IndicesRequestCache` and `IndicesQueryCache`
from guice and moves it into `IndicesService`. It also decouples the `IndexShard` and `IndexService`
from these caches which are unnecessary dependencies.
QueryBuilders today do all their heavy lifting in toQuery() which
can be too late for several operations. For instance if we want to fetch geo shapes
on the coordinating node we need to do all this before we create the actual lucene query
which happens on the shard itself. Also optimizations for request caching need to be done
to the query builder rather than the query which then in-turn needs to be serialized again.
This commit adds the basic infrastructure for query rewriting and moves the heavy lifting into
the rewrite method for the following queries:
* `WrapperQueryBuilder`
* `GeoShapeQueryBuilder`
* `TermsQueryBuilder`
* `TemplateQueryBuilder`
Other queries like `MoreLikeThisQueryBuilder` still need to be fixed / converted. The nice
sideeffect of this is that queries like template queries will now also match the request cache
if their non-template equivalent has been cached befoore. In the future this will allow to
add optimizataion like rewriting time-based queries into primitives like `match_all_docs` or `match_no_docs`
based on the currents shards bounds. This is especially appealing for indices that are read-only ie. never change.
In the testCanFetchIndexStatus the task check can occur before the indexing process is started making the test to fail. This commit adds an additional lock to make sure we check tasks only after at least one of the tasks is registered.
This commit removes bootstrap support for Java Service Wrapper. The
implementation of this has been moved to its own repository where it was
deprecated, does not work with Elasticsearch 2.x, and is untested and
therefore unmaintained.
Closes#16580
This commit handles the scenario where a replication action fails on a
replica shard, the primary shard attempts to fail the replica shard
but the primary shard is notified of demotion by the master. In this
scenario, the demoted primary shard must be failed, and then the
request rerouted again to the new primary shard.

Only tasks that extend CancellableTask can be cancelled using this mechanism. If a cancellable task has children it can elect to cancel all child tasks as well. In this case a special ban parent request is sent to all nodes. This request does two things: 1) it prevents any tasks with the banned parent task from being started, and 2) it cancels all currently running tasks that have the banned task as a parent. The ban is lifted as soon as the coordinating node notifies all other nodes that the cancelled task has finished executing. If the coordinating node leaves the cluster before it has a chance to lift its bans, all bans set by this coordinating node are automatically removed.
As an option a task can elect to automatically cancel all child tasks if their parent task was running on a node that just left the cluster. This option makes sense for cancellable heavy tasks that have no side-effects and only return results to the coordinating node. With the coordinating node gone, it doesn't make sense to run such tasks any longer since their results will be most likely discarded.
That is like some kind of cardinal sin or something, right?
We had two violations though they weren't super likely to be keys in a hashmap
any time soon.
This is a simple port of the mapper attachment plugin to the ingest

The purpose of this commit is to speed up the runtime of
MessageDigestTests#testToHexString. As written, the test contains a loop
that creates 1024 test cases leading to a test runtime on the order of a
few seconds. Given build infrastructure, a single test case should
suffice. Therefore, this commit removes this loop so that the test can
execute on the order of a couple hundred milliseconds.
This commit includes a few minor cleanups to o/e/b/JavaVersion.java:

IndexShard currently holds an arbitraritly used `getQueryShardContext` that comes
out of a ThreadLocal. It's usage is undefined and arbitraty since there is also
such a method with different semantics on `IndexService` This commit removes the threadLocal on
IndexShard as well as on the context itself. It's types are now a member and the QueryShardContext
lifecycle is managed byt SearchContext which passes the types on from the SearchRequest.
Recovery from store fails to correctly set the translog recovery stats. This fixes it and tightens up the logic bringing it all to IndexShard (previously it was set by the recovery logic).

There is no need for IndicesWarmer to be a global accessible class. All it needs
access to is inside IndexService. It also doesn't need to be mutable once it's not a per node
instance. This commit move IndicesWarmer to IndexWarmer and makes the default impls like field data and
norms warming an impl detail. Also the IndexShard doesn't depend on this class anymore, instead it accepts
an Engine.Warmer as a ctor argument which delegates to the actual warmer from the index.
The cat API previously used the Content-Type header field for

One of our tests leaked a system property here since we failed after appling some
system properties in BootstrapCLIParser. This is not a huge deal in production since
we exit the JVM if we fail on that. Yet for correctnes we should only apply them if
we manage to parse them all.
This also caused a test failure lately on CI but on an unrelated test:

Indices level field data cacheing belongs into IndicesService and doesn't need to be

This processor is useful when all elements of a json array need to be processed in the same way.
This avoids that a processor needs to be defined for each element in an array.
Also it is very likely that it is unknown how many elements are inside an json array.
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.
During initial cluster forming, when a master is elected, it reaches out to all other masters nodes and ask the last cluster state they persisted. To make sure we select the right state, we must successfully read from a `min_master_nodes` nodes. The gateway currently have specific settings to override this behavior, but I don't think they are ever used. We can drop them and reach out to the discovery layer, the single source of truth for the min master nodes settings.

Uses a refactored version of Netty's CORS implementation to provide more

It has also been refactored in a way that allows dropping in Netty's
CORS handler as a replacement once Elasticsearch is upgraded to Netty 4.
This change rewrites the entire settings filtering mechanism to be immutable.

This commit modifies the string representation of a shard state action
request. The issue being addressed is that the previous logging would
log "failure: [Unknown]" for shard started actions but this just leads
to confusion that there is a failure but its cause is unknown.
Closes#16396
Today, shard failure requests are blindly handled on the master without
any validation that the request is a legal request. A legal request is a
shard failure request for which the shard requesting the failure is
either the local allocation or the primary allocation. This is because
shard failure requests are classified into only two sets: requests that
correspond to shards that exist, and requests that correspond to shards
that do not exist. Requests that correspond to shards that do not exist
are immediately marked as successful (there is nothing to do), and
requests that correspond to shards that do exist are sent to the
allocation service for handling the failure.
This pull request adds a third classification for shard failure requests
to separate out illegal shard failure requests and enables the master to
validate shard failure requests. The master communicates the illegality
of a shard failure request via a new exception:
NoLongerPrimaryShardException. This exception can be used by shard
failure listeners to discover when they've sent a shard failure request
that they were not allowed to send (e.g., if they are no longer the
primary allocation for the shard).
Closes#16275
Identifying when a plugin id is maven coordinates is currently done by

contain a slash, which only a url would have.

This commit enableds strict settings validation on node startup. All settings
passed to elasticsearch either through system properties, yaml files or any other
way to pass settings must be registered and valid. Settings that are unknown ie. due to
typos or due to deprecation or removal will cause the node to NOT start up. Plugins
have to declare all their settings on the `SettingsModule#registerSetting` and settings for
plugins that are not installed must be removed.
This commit also removes the ability to specify the nodes name via `-Des.name` or just `name` in the
configuration files. The node name must be prefixed with the node prexif like `node.name: Boom`. Left over
usage of `name` will also cause startup to fail.

When primary relocation completes, a cluster state is propagated that deactivates the old primary and marks the new primary as active.
As cluster state changes are not applied synchronously on all nodes, there can be a time interval where the relocation target has processed
the cluster state and believes to be the active primary and the relocation source has not yet processed the cluster state update and
still believes itself to be the active primary. This commit ensures that, before completing the relocation, the reloction source deactivates
writing to its store and delegates requests to the relocation target.

Cli tools currently catch all exceptions, and only print the exception
message, except when a special system property is set. Even with this
flag set, certain exceptions, like IOException, are captured and their
stack trace is always lost.
This change adds a UserError class, which can be used a cli tools to
specify a message to the user, as well as an exit status. All other
exceptions are propagated out of main, so java will exit with non-zero
and print the stack trace.
This commit fixes an inconsistency between ShardId#equals(Object),
ShardId#hashCode, and ShardId#compareTo(ShardId). In particular,
ShardId#equals(Object) compared only the numerical shard ID and the
index name, but did not compare the index UUID; a similar situation
applies to ShardId#compareTo(ShardId). However, ShardId#hashCode
incorporated the indexUUID into its calculation. This can lead to
situations where two ShardIds compare as equal yet have different hash
codes.

The plugin cli currently is extremely lenient, allowing most errors to
simply be logged. This can lead to either corrupt installations (eg
partially installed plugins), or confused users.
This change rewrites the plugin cli to have almost no leniency.
Unfortunately it was not possible to remove all leniency, due in
particular to how config files are handled.
The following functionality was simplified:
* The format of the name argument to install a plugin is now an official
plugin name, maven coordinates, or a URL.
* Checksum files are required, and only checked, for official plugins
and maven plugins. Checksums are also only SHA1.
* Downloading no longer uses a separate thread, and no longer has a timeout.
* Installation, and removal, attempts to be atomic. This only truly works
when no config or bin files exist.
* config and bin directories are verified before copying is attempted.
* Permissions and user/group are no longer set on config and bin files.
We rely on the users umask.
* config and bin directories must only contain files, no subdirectories.
* The code is reorganized so each command is a separate class. These
classes already existed, but were embedded in the plugin cli class, as
an extra layer between the cli code and the code running for each command.
With the recent change to allow ESSingleNodeTestCase to specify plugins

change makes those methods non-static.

Previously it's possible to get errors like:
```
Caused by: NotSerializableExceptionWrapper[d:\shared_data\afs-issue-1-1\23]

Which doesn't tell us what the underlying exception type was that could

This changes the message to prepend the

This commit amends a logging statement in TransportReplicationAction to

Does so by introducing TaskListener which is just like ActionListener but
gets the Task as each parameter. Unlike ActionListener which is used
_everywhere_ you can only use TaskListener directly with TransportAction.
TransportAction under the covers uses an ActionListener implemetation that

Note for many of the settings we had a netty specific override to a generic transport setting. I have removed those as they are not needed imo (ex. "transport.connections_per_node.recovery" was overriden by "transport.netty.connections_per_node.recovery", which I removed). The netty prefix was kept for settings that are tied to the netty universe - ex. "transport.netty.max_cumulation_buffer_capacity"

Today our logger settings are treated differently than all other
settings. This was a shortcut / workaround since it's quite messy but now
that we have strict validation and transactional updates we should integrate the

Logger settings now also updateable and resetttable by passing `null`
In the early days Elasticsearch used to use the index name as the index identity. Around 1.0.0 we introduced a unique index uuid which is stored in the index setting. Since then we used that uuid in a few places but it is by far not the main identifier when working with indices, partially because it's not always readily available in all places.
This PR start to make a move in the direction of using uuids instead of name by making sure that the uuid is available on the Index class (currently just a wrapper around the name) and as such also available via ShardRouting and ShardId.
Note that this is by no means an attempt to do the right thing with the uuid in all places. In almost all places it falls back to the name based comparison that was done before. It is meant as a first step towards slowly improving the situation.
Closes#16217
Adds unit tests for blob operations and integration tests for repository operations. These tests can be used by repository plugins to verify that repository operations were implemented as expected by BlobStoreRepository.
These methods allow to modify and retrieve the content of pipelines, which are stored in the cluster state. Their actions names were already correct under the category cluster:admin/ingest/pipeline/* , the corresponding methods should be moved under client.admin().cluster() .
If we don't do this, and some path.conf is set when starting the tribe node, that path.conf will be ignored and the inner tribe clients will try to read elsewhere, where they most likely don't have permissions to read from.

This commit method renames the ScriptEngineService interface methods

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
Doc values can now only be enabled by setting `doc_values: true` in the
mappings. Removing this feature also means that we can now fail mapping updates
that try to disable doc values.
Parsing is currently very lenient, which has the bad side-effect that if you
have a typo and pass eg. `store: fasle` this will actually be interpreted as
`store: true`. Since mappings can't be changed after the fact, it is quite bad
if it happens on an index that already contains data.
Note that this does not cover all settings that accept a boolean, but since the
PR was quite hard to build and already covers some main settirgs like `store`
or `doc_values` this would already be a good incremental improvement.
Doc values currently default to `true` if the field is indexed and not analyzed.
So setting `index:no` automatically disables doc values, which is not explicit
in the documentation.
This commit makes doc values default to true for numerics, booleans regardless
of whether they are indexed. Not indexed strings still don't have doc values,
since we can't know whether it is rather a text or keyword field. This
potential source of confusion should go away when we split `string` into `text`
and `keyword`.
This commit adds handling on the master side for shard failure requests
for shards that do not exist at the time that they are processed on the
master node (whether it be from errant requests, duplicate requests, or
both the primary and replica notifying the master of a shard
failure). This change is made because such shard failure requests should
always be considered successful (the failed shard is not there anymore),
but could be marked as failed if batched with a shard failure request
that does in fact fail. This avoids the possibility of an unexpected
catastrophic failure while applying the failed shards from causing such
a request to also be marked as failed setting in motion additional
failures.

RescoreBuilder: Add parsing and creating of RescoreSearchContext

When a Version is passed to `Settings#put(String, Version)` it's id is used as

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.
The current RescoreBaseBuilder only serves as a container
for a pair of the optional `window_size` parameter and
the actual rescorer. Instead of a wrapper object, this makes
it an abstract class that conrete implementations like
QueryRescoreBuilder can extend.
With this commit we deprecate the widely misunderstood
fuzzy query but will still allow the fuzziness
parameter in match queries and suggesters.

This commit removes non-reproducible randomness from
SearchWhileCreatingIndexIT. The cause of the non-reproducible randomness
is the use of a random draws for the shard preference inside of a
non-deterministic while loop. Because the inner while loop executed a
non-deterministic number of times, the draws for the next iteration of
the outer loop would be impacted by this making the random draws
non-reproducible. The solution is to move the random draws outside of
the while loop (just make a single draw for the prefernce and increment
with a counter), and remove the outer loop iteration instead using an
annotation to get the desired repetitions.

Breaking (but I think acceptable) - network.tcp.no_delay and network.tcp.keep_alive used to accept the value `default` which make us not set them at all on netty. Our default was true so we weren't using this feature. I removed it and now we only accept a true boolean.

PhraseSuggestionBuilder uses three smoothing models internally.
In order to enable proper serialization / parsing from xContent

Today we run the metadata upgrade only on the current major version
but this should run on every upgrade at least once to ensure we don't miss
an important check or upgrade.
This commit fixes a minor issue with the shard ID that is logged while
indexing in DiscoveryWithServiceDisruptionsIT#testAckedIndexing. The
issue is that the operation routing hash could lead to a negative
remainder modulo the number of primaries (if the hash itself is
negative) but should instead be the normalized positive remainder. This
issue only impacts the logging of the shard ID as the actual shard ID
used during indexing is computed elsewhere but would cause the shard ID
in the affected logging statement to not match shard IDs that are logged
elsewhere.
