[jira] [Commented] (HBASE-7471) Enable Cleaners required for
Snapshots by default?
[ https://issues.apache.org/jira/browse/HBASE-7471?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13541543#comment-13541543 ]
Jonathan Hsieh commented on HBASE-7471:
---------------------------------------
This needs double checking, but i believe:
* zk doesn't add threads. (all ZK listeners should be dispatched from the same thread)
* subprocedure pool shouldn't have much impact if we chose the right kind of thread pool (e.g. one that kills off threads if they are all idle).
* procedures and subprocedures don't use threads until they are kicked off.
