----------------------------------------
Okay, I am working on this.
> 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
> Priority: Minor

> 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.
