Long ago (#7834) the owner ship of the local disco node was centralized to the cluster service. LocalDiscovery is still created it's own disco node, which is not used by the cluster service and thus creating confusion (two nodes same name but different ids).
This commit also removes and optimization where when joining a new master we would first copy the master's metadata and only then pull in the rest of the cluster state (and it's nodes).
Closes#16317
This commit adds a tip to the setup docs for how to detect whether the
user is running on a system that uses SysV-style init versus systemd.
Closes#16323
This commit removes and forbids the use of lowercase ells ('l') in long
literals because they are often hard to distinguish from the digit
representing one ('1').
Closes#16329
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
not be serialized.
This changes the message to prepend the
`ElasticsearchException.getExceptionName()` of the exception (which is a
underscore case of the class with the leading 'Elasticsearch' removed)
This adds a small pile of checkstyle checks that all pass without any changes.
It moves some checks from ForbiddenPatterns that were java only into
checkstyle.
Don't duplicate forbiddenPatterns in checkstyle
This setting was missing from the docs, so I added it. However, I also
completely rewrote the nodes documentation page because it was mostly
talking about client nodes with some issues, without ever discussing
master nodes, or even tribe nodes. All nodes should be listed on a
"nodes" documentation page.
Fixes#15903Fixed#14429
This commit amends a logging statement in TransportReplicationAction to
log the full shard ID instead of just the numerical shard ID (without
the index name).
When there is an exception thrown during pipeline creation within
Rest calls (in put pipeline, and simulate) We now return a structured
error response to the user with details around which processor's
configuration is the cause of the issue, or which configuration property
is misconfigured, etc.
We are leaking all kinds of resources if something during Node#close() barfs.
This commit cuts over to a list of closeables to release resources that
also closed remaining services if one or more services fail to close.
Closes#13685
This is an issue due to some refactoring we did along the lines of Index.java etc.
We pass the index object to Set#contains which should actually be only it's name.
Closes#16299
This can cause premature closing of the underlying file descriptor immediately
if at the same time the thread is blocked on IO. The file descriptor will remain closed
and subsequent access to NIOFSDirectory will throw a ClosedChannelException.
In junit5, a neat assertion method is added which makes testing expected
failures a little more straightforward. The block of code that is
expected to throw is passed in with a lambda expression, and the caught
exception returned for inspection.
This change adds an implementation of expectThrows to ESTestCase. When
junit5 is eventually releassed and we switch to it, we can remove.
Adds a method that emits a WordScorerFactory to all of the
three SmoothingModel implementatins that will be needed when
we switch to parsing the PhraseSuggestion on the coordinating
node and need to delay creating the WordScorer on the shards.
