Anoop Sam John commented on HBASE-15439:
----------------------------------------
>From log it is clear that the chore threads wakes up after the configured
>period ie. 100 minutes. The decision for skip is 1.5 times of the period..
>Strange !

> Mob compaction is not triggered after extended period of time
