-----------------------------

             Summary: Use StealJobQueue in HFileCleaner after HBASE-17215
                 Key: HBASE-17854
                 URL: https://issues.apache.org/jira/browse/HBASE-17854
             Project: HBase
          Issue Type: Improvement
    Affects Versions: 2.0
            Reporter: Yu Li
            Assignee: Yu Li


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.
