---------------------------------
Comment: was deleted
(was: Looks good to me, thanks [~carp84]. I checked that the initial capacity for PriorityBlockingQueue is 11 in Java 8, is this too small? Maybe we can add a new constructor for StealJobQueue to specify initialCapacity.)

> In HBASE-17215 we use specific threads for deleting large/small (archived) hfiles, and will improve it from below aspects in this JIRA:
> 1. Using {{StealJobQueue}} to allow large file deletion thread to steal jobs from small queue, based on the experience that in real world there'll be much more small hfiles
> 2. {{StealJobQueue}} is a kind of {{PriorityQueue}}, so we could also delete from the larger file in the queues.
