Decommissioning a node or applying a filter inclusion / exclusion can potentially lead to many shards that need to be moved to other nodes. This commit reuses the model across all
shard movements in an allocation round: It calculates the shard model once and simulates the application of all shards that can be moved on this model.
Closes#16926
Today we might run into a rejected execution exception when
we shutdown the node while handling a transport exception. The
exception is run in a seperate thread but that thread might
not be able to execute due to the shutdown. Today we barf and fill
the logs with large exception. This commit catches this exception
and logs it as debug logging instead.
Remove support for legacy checksums
Elasticsearch 5.0 doesn't support indices with legacy checksums anymore.
The last time we write legacy checksums was in 1.3.0 which was based
on lucene 4.9 already which means that all files have CRC32 checksums.
All indices that Elasticsearch can read today must be written with
lucene version >= 4.8 anyway so we can drop this layer of backwards
compatibility entirely.
Since we are close to upgrading to Lucene 6.0 we should get rid of this
in a more contained change than the lucene upgrade.

On shared FS / shadow replicas we rely on a lock retry if the lock has
not yet been relesed on a relocated primary. This commit adds this `hack`
for shared filesystems only.
Closes#16936
The field name is a required argument for all suggesters, but
it was specified via a field() setter in SuggestionBuilder so far.
This changes field name to being a mandatory constructor argument
and lets suggestion builders throw an error if field name is missing
or the empty string.
This commit modifies TransportBulkAction to use relative time instead of
absolute time when measuring how long a bulk request took to be
processed, and adds tests for this functionality.
Closes#16916
`writeLockTimeout` has been removed in Lucene 6 completely and since we have
the shard locking mechanism now for quite a while we don't need this anymore.
Shards should only be allocated once all resources are released such that there
can't be any other shard holding the lock to that index in any sane situation.
