Sean Busbey commented on HBASE-23038: ------------------------------------- thanks for taking this up! can you remove the case in HMaster where we fetch the MobCompactionChore period and check it to log a similar message? > Provide consistent and clear logging about disabling chores > ----------------------------------------------------------- > > Key: HBASE-23038 > URL: https://issues.apache.org/jira/browse/HBASE-23038 > Project: HBase > Issue Type: Improvement > Components: master, regionserver > Reporter: Sean Busbey > Assignee: Sanjeet Nishad > Priority: Minor > Labels: beginner > Attachments: HBASE-23038.001.patch, HBASE-23038.002.patch > > > Right now if you want to disable any of our chores you can set the period to > be <= 0. Sometimes, if you do this you get a nice message: > {code} > 2019-09-16 22:10:16,756 INFO [master-1:16000.activeMasterManager] > master.HMaster: The period is 0 seconds, MobCompactionChore is disabled > {code} > And sometimes you get an opaque message: > {code} > 2019-09-16 22:09:45,333 INFO [master-1:16000.activeMasterManager] > hbase.ChoreService: Could not successfully schedule chore: LogsCleaner > 2019-09-16 22:09:45,340 INFO [master-1:16000.activeMasterManager] > hbase.ChoreService: Could not successfully schedule chore: HFileCleaner > {code} > This is because sometimes we just blindly submit to ChoreService which > submits to a java ScheduledExecutorService and then catches the > IllegalArgumentException. > We should remove the one-offs and make it so ChoreService checks the period > before accepting a submittal and produces a consistent "Foo is disabled" > message. -- This message was sent by Atlassian Jira (v8.3.4#803005)
