Backport of #38818 to `7.x`. Original description:
The HTTP exporter code in the Monitoring plugin makes `GET _template` requests to check for existence of templates. These requests don't need to pass the `include_type_name` query parameter so this PR removes it from the request. This should remove the following deprecation log entries on the Monitoring cluster in 7.0.0 onwards:
```
[types removal] Specifying include_type_name in get index template requests is deprecated.
```
The java time formatter used in the exporter adds a plus sign to the
year, if a year with more than five digits is used. This changes the
creation of those timestamp to only have a date up to 9999.
Closes#38378
The test was relying on toString in ZonedDateTime which is different to
what is formatted by strict_date_time when milliseconds are 0
The method is just delegating to dateFormatter, so that scenario should
be covered there.
closes#38359
Backport #38610
This PR removes the use of document types from the monitoring exporters and template + watches setup code.
It does not remove the notion of types from the monitoring bulk API endpoint "front end" code as that code will eventually just go away in 8.0 and be replaced with Beats as collectors/shippers directly to the monitoring cluster.
Scheduler.schedule(...) would previously assume that caller handles
exception by calling get() on the returned ScheduledFuture.
schedule() now returns a ScheduledCancellable that no longer gives
access to the exception. Instead, any exception thrown out of a
scheduled Runnable is logged as a warning.
This is a continuation of #28667, #36137 and also fixes#37708.
This deprecates the `xpack.watcher.history.cleaner_service.enabled` setting,
since all newly created `.watch-history` indices in 7.0 will use ILM to manage
their retention.
In 8.0 the setting itself and cleanup actions will be removed.
Resolves#32041
This commit moves the aggregation and mapping code from joda time to
java time. This includes field mappers, root object mappers, aggregations with date
histograms, query builders and a lot of changes within tests.
The cut-over to java time is a requirement so that we can support nanoseconds
properly in a future field mapper.

The AbstracLifecycleComponent used to extend AbstractComponent, so it had to pass settings to the constractor of its supper class.
It no longer extends the AbstractComponent so there is no need for this constructor
There is also no need for AbstracLifecycleComponent subclasses to have Settings in their constructors if they were only passing it over to super constructor.
This is part 1. which will be backported to 6.x with a migration guide/deprecation log.
part 2 will have this constructor removed in 7

* Default include_type_name to false for get and put mappings.
* Default include_type_name to false for get field mappings.
* Add a constant for the default include_type_name value.
* Default include_type_name to false for get and put index templates.
* Default include_type_name to false for create index.
* Update create index calls in REST documentation to use include_type_name=true.
* Some minor clean-ups around the get index API.
* In REST tests, use include_type_name=true by default for index creation.
* Make sure to use 'expression == false'.
* Clarify the different IndexTemplateMetaData toXContent methods.
* Fix FullClusterRestartIT#testSnapshotRestore.
* Fix the ml_anomalies_default_mappings test.
* Fix GetFieldMappingsResponseTests and GetIndexTemplateResponseTests.
We make sure to specify include_type_name=true during xContent parsing,
so we continue to test the legacy typed responses. XContent generation
for the typeless responses is currently only covered by REST tests,
but we will be adding unit test coverage for these as we implement
each typeless API in the Java HLRC.
This commit also refactors GetMappingsResponse to follow the same appraoch
as the other mappings-related responses, where we read include_type_name
out of the xContent params, instead of creating a second toXContent method.
This gives better consistency in the response parsing code.
* Fix more REST tests.
* Improve some wording in the create index documentation.
* Add a note about types removal in the create index docs.
* Fix SmokeTestMonitoringWithSecurityIT#testHTTPExporterWithSSL.
* Make sure to mention include_type_name in the REST docs for affected APIs.
* Make sure to use 'expression == false' in FullClusterRestartIT.
* Mention include_type_name in the REST templates docs.
This commit removes the fallback for SSL settings. While this may be
seen as a non user friendly change, the intention behind this change
is to simplify the reasoning needed to understand what is actually
being used for a given SSL configuration. Each configuration now needs
to be explicitly specified as there is no global configuration or
fallback to some other configuration.
Closes#29797
Added warnings checks to existing tests
Added “defaultTypeIfNull” to DocWriteRequest interface so that Bulk requests can override a null choice of document type with any global custom choice.

Today, a setting can declare that its validity depends on the values of other
related settings. However, the validity of a setting is not always checked
against the correct values of its dependent settings because those settings'
correct values may not be available when the validator runs.
This commit separates the validation of a settings updates into two phases,
with separate methods on the `Setting.Validator` interface. In the first phase
the setting's validity is checked in isolation, and in the second phase it is
checked again against the values of its related settings. Most settings only
use the first phase, and only the few settings with dependencies make use of
the second phase.
As suggested in #36775, this pull request renames the following methods:
ClusterBlocks.hasGlobalBlock(int)
ClusterBlocks.hasGlobalBlock(RestStatus)
ClusterBlocks.hasGlobalBlock(ClusterBlockLevel)
to something that better reflects the property of the ClusterBlock that is searched for:
ClusterBlocks.hasGlobalBlockWithId(int)
ClusterBlocks.hasGlobalBlockWithStatus(RestStatus)
ClusterBlocks.hasGlobalBlockWithLevel(ClusterBlockLevel)
This commit moves back to use explicit dependsOn for test tasks on
check. Not all tasks extending RandomizedTestingTask should be run by
check directly.
We have a few places where we register license state listeners on
transient components (i.e., resources that can be open and closed during
the lifecycle of the server). In one case (the opt-out query cache) we
were never removing the registered listener, effectively a terrible
memory leak. In another case, we were not un-registered the listener
that we registered, since we were not referencing the same instance of
Runnable. This commit does two things:
- introduces a marker interface LicenseStateListener so that it is
easier to identify these listeners in the codebase and avoid classes
that need to register a license state listener from having to
implement Runnable which carries a different semantic meaning than
we want here
- fixes the two places where we are currently leaking license state
listeners
This commit changes the format of the `hits.total` in the search response to be an object with
a `value` and a `relation`. The `value` indicates the number of hits that match the query and the
`relation` indicates whether the number is accurate (in which case the relation is equals to `eq`)
or a lower bound of the total (in which case it is equals to `gte`).
This change also adds a parameter called `rest_total_hits_as_int` that can be used in the
search APIs to opt out from this change (retrieve the total hits as a number in the rest response).
Note that currently all search responses are accurate (`track_total_hits: true`) or they don't contain
`hits.total` (`track_total_hits: true`). We'll add a way to get a lower bound of the total hits in a
follow up (to allow numbers to be passed to `track_total_hits`).

- make it easier to add additional testing tasks with the proper configuration and add some where they were missing.
- mute or fix failing tests
- add a check as part of testing conventions to find classes not included in any testing task.
This commit is part of our plan to deprecate and ultimately remove the
use of _xpack in the REST APIs.
* Add deprecation for /_xpack/monitoring/_bulk in favor of /_monitoring/bulk
* Removed xpack from the rest-api-spec and tests
* Removed xpack from the Action name
* Removed MonitoringRestHandler as an unnecessary abstraction
* Minor corrections to comments

This changes the exporter code -- most notably the `http` exporter --
to use async operations throughout the resource management and bulk
initialization code (the bulk indexing of monitoring documents was
already async).
As part of this change, this does change one semi-core aspect of the
`HttpResource` class in that it will no longer block all concurrent calls
until the first call completes with
`HttpResource::checkAndPublishIfDirty`.
Now, any parallel attempts to check the resources will be skipped until
the first call completes (success or failure). While this is a technical
change, it has very little practical impact because the existing behavior
was either quick success (then every blocked request processed) or
each request timed out and failed anyway, thus being effectively
skipped (and a burden on the system).
This commit removes the use of AbstractComponent in xpack where it was
still being extended. It has been replaced with explicit logger
declarations.
See #34488
Today we have a way to atomically persist global MetaData and
IndexMetaData to disk when new ClusterState is received. All other
ClusterState fields are not persisted.
However, there are other parts of ClusterState that should be
persisted, namely:
version
term
lastCommittedConfiguration
lastAcceptedConfiguration
votingTombstones
version is changed frequently, other fields are not. We decided
to group term, lastCommittedConfiguration,
lastAcceptedConfiguration and votingTombstones into
CoordinationMetaData class and make CoordinationMetaData a field
inside MetaData.
MetaData.toXContent and MetaData.fromXContent should take care of
CoordinationMetaData.
version stays as a top level field in ClusterState and will be
persisted as part of Manifest in a follow-up commit.
Also MetaData.isGlobalStateEquals should be extended to include
coordinationMetaData in comparison.
This commit favors exposing getters, such as getTerm directly in
ClusterState to avoid massive code changes.
An example of CoordinationMetaState.toXContent:
{
"term": 1,
"last_committed_config": [
"TiIuBcbBtpuXyDDVHXeD",
"ZIAoVbkjjLPLUuYLaTkw"
],
"last_accepted_config": [
"OwkXbXZNOZPJqccdFHdz",
"LouzsGYwmQzpeQMrboZe",
"fCKGRZdjLTqzXAqPUtGL",
"pLoxshjpJXwDhbgjfYJy",
"SjINLwFIlIEFZCbjrSFo",
"MDkVncJEVyZLJktopWje"
]
}
Today our OS information returned in node stats only returns a
high-level name of the OS (e.g., "Linux"). Yet, for some uses this is
too high-level and knowing at a finer level of granularity the
underlying OS can be useful. This commit extracts the pretty name on
Linux from /etc/os-release. This pretty name usually includes the Linux
vendor and the Linux vendor version number (e.g., Fedora 28).
With this change, `Version` no longer carries information about the qualifier,
we still need a way to show the "display version" that does have both
qualifier and snapshot. This is now stored by the build and red from `META-INF`.
This is a forward port of some of the changes made in #8445, specifically the change mentioned in https://github.com/elastic/elasticsearch/pull/34023#issuecomment-433212636.
Currently, in master, the `cluster_stats` collector collects _all_ cluster metadata and indexes it into `.monitoring-es-*`. However, per the discussion linked to above, we decided to collect _only_ the `display_name` cluster metadata setting for now. This PR makes this change.
Stop passing `Settings` to `AbstractComponent`'s ctor. This allows us to
stop passing around `Settings` in a *ton* of places. While this change
touches many files, it touches them all in fairly small, mechanical
ways, doing a few things per file:
1. Drop the `super(settings);` line on everything that extends
`AbstractComponent`.
2. Drop the `settings` argument to the ctor if it is no longer used.
3. If the file doesn't use `logger` then drop `extends
AbstractComponent` from it.
4. Clean up all compilation failure caused by the `settings` removal
and drop any now unused `settings` isntances and method arguments.
I've intentionally *not* removed the `settings` argument from a few
files:
1. TransportAction
2. AbstractLifecycleComponent
3. BaseRestHandler
These files don't *need* `settings` either, but this change is large
enough as is.
Relates to #34488
Drops the `Settings` member from `AbstractComponent`, moving it from the
base class on to the classes that use it. For the most part this is a
mechanical change that doesn't drop `Settings` accesses. The one
exception to this is naming threads where it switches from an invocation
that passes `Settings` and extracts the node name to one that explicitly
passes the node name.
This change doesn't drop the `Settings` argument from
`AbstractComponent`'s ctor because this change is big enough as is.
We'll do that in a follow up change.
Conflicts during the merge:
1. >=140 chars line length fixed for a lot of project files and warnings
for those files are no longer suppressed
2. Node name is removed from AbstractComponent, it’s no longer taken
from settings, but is explicitly passed as constructor argument and
there were quite a few new classes on zen2 branch that require this
change
3. TransportResponseHandler interface changed (new method added) and
Zen2 makes a lot of subclasses in tests
4. Deprecated way of obtaining logger was changed
This commit fixes two issues with the CCR API specification:
- remove the CCR stats endpoint, it is not currently implemented
- fix the documentation links
* Changed the auto follow stats to also include follow stats.
* Renamed the auto follow stats api to stats api and changed its url path
from `/_ccr/auto_follow/stats` `/_ccr/stats`.
* Removed `/_ccr/stats` url path for the follow stats api, which makes
the index parameter a required parameter.
* Fixed docs.
With this change, we apply the common test config automatically to all
newly created tasks instead of opting in specifically.
For plugin authors using the plugin externally this means that the
configuration will be applied to their RandomizedTestingTasks as well.
The purpose of the task is to simplify setup and make it easier to
change projects that use the `test` task but actually run integration
tests to use a task called `integTest` for clarity, but also because
we may want to configure and run them differently.
E.x. using different levels of concurrency.
In the CCR docs we want to refer to the endpoint that returns following
stats as the follow stats API. This commit renames the internal
implementation of this endpoint to reflect this usage.
