> 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.
