Subject [jira] [Commented] (HBASE-20808) Wrong shutdown order between Chores and ChoreService
Date Sun, 01 Jul 2018 07:49:00 GMT

    [ https://issues.apache.org/jira/browse/HBASE-20808?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16529003#comment-16529003

Nihal Jain commented on HBASE-20808:

{quote}For a logic clear code base, having a clear start getChoreService().scheduleChore(ScheduledChore);,
it is better to have a clear end getChoreService().cancelChore(ScheduledChore);.
Isn't it sometimes better to have a cleaner solution than an ideal solution? 

Anyways, I have attached a new patch with the suggested change: [^HBASE-20808.master.002.patch]

> When stopping master, {{ChoreService}}, which serves all the chores, is stopped before
canceling all running chores.
> It should cancel all running chores, then shutdown {{ChoreService}}.
