[jira] [Commented] (SOLR-12464) reduce Overseer.close() logging
(for non-Overseer leaders)
[ https://issues.apache.org/jira/browse/SOLR-12464?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16504833#comment-16504833 ]
Christine Poerschke commented on SOLR-12464:
--------------------------------------------
The attached demo SOLR-12464-ea.patch in conjunction with the SOLR-12462.patch shows the 'release of untracked object' behaviour when starting/stopping a cloud (with external zookeeper, have not tried with embedded zookeeper). SOLR-12464-ea.patch is _not_ intended to be committed.

> ZkController.init creates an Overseer object:
> * If that object becomes overseer leader then its start method is called.
> * If the object does not become overseer leader then its close method is called and that currently emits mildly confusing {{Overseer (id=null) closing}} info logging -- confusing especially since this happens at node startup.
> ZkController.init creates an Overseer object:
> * If that object becomes overseer leader then its start method is called and (if assertions are enabled) ObjectReleaseTracker.track is called.
> * If the object does not become overseer leader then its close method is called and (if assertions are enabled) ObjectReleaseTracker.release is called despite ObjectReleaseTracker.track not having been called previously.
