Subject [jira] [Commented] (HBASE-20095) Redesign single instance pool in CleanerChore
Date Tue, 27 Mar 2018 02:40:00 GMT

    [ https://issues.apache.org/jira/browse/HBASE-20095?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16414919#comment-16414919
] 

Reid Chan commented on HBASE-20095:
-----------------------------------

Looks like an edge case,
pool in {{updatePool(long)}} is in synchronized, chore should not submit task successfully
until updating finishes.
If POOL.submit() is called first (also synchronized), canUpdateImmediately (also synchronized)
shall return false.
WDYT, [~yuzhihong@gmail.com]?
