after HBASE-17215
Yu Li created HBASE-17854:
-----------------------------
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.
