This commit splits cluster state update tasks into roles. Those roles
are:
- task info
- task configuration
- task executor
- task listener
All tasks that have the same executor will be executed in batches. This
removes the need for local batching as was previously in
MetaDataMappingService.
Additionally, this commit reintroduces batching on mapping update calls.

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".
Removed check that two query builder that are different according
to equals() have different hashCode since that is not required
by the contract of hashCode.
We used to check on several places if we are still open but non of these
places did the check under the lock which leaves a small window where we
potentially get closed but still access an already closed channel or another
IO resource.
This is a pretty trivial change that moves most of the monitor service related
object creation from guice into the monitor service. This is a babystep towards removing
guice on the node level as well. Instead of opening huge PRs I try to do this in baby-steps
that are easier to digest.
We handle AlreadyClosedExceptions gracefully wherever IndexShard / Engine
is used. In some cases, instead of throwing the appropriate exception we
bubble up ChannelClosedException instead which causes shard failures etc.
Today, it seems like that this can only happen if the engine is closed without
acquireing the lock which means that the shard has failed already so the impact is really
just a confusing log message. Yet, this change enforces throwing the right exception
if the translog is already closed.
Closes#14866
This moves the registration of field mappers from the index level to the node
level and also ensures that mappers coming from plugins are treated no
differently from core mappers.
This commit fixes some leniency in the parsing of CIDRs. The leniency
that existed before includes not validating the octet values nor
validating the network mask; in some cases issues with these values were
silently ignored. Parsing is now done according to the guidelines in RFC
4632, page 6.
Closes#14862
For example: if a node left the cluster and an async store fetch was triggered. In that time no shard is marked as delayed (and strictly speaking it's not yet delayed). This caused test for shard delays post node left to fail. see : http://build-us-00.elastic.co/job/es_core_master_windows-2012-r2/2074/testReport/
To fix this, the delay update is now done by the Allocation Service, based of a fixed time stamp that is determined at the beginning of the reroute.
Also, this commit fixes a bug where unassigned info instances were reused across shard routings, causing calculated delays to be leaked.
Closes#14890
This switches query parsing from manual field parsing to using ParseField.
Also adds unit tests for each query that check original json can be parsed
into query builders.
