Changgeng Li commented on HBASE-13560:
--------------------------------------

The test still pass if we shutdown the short compaction thread pool instead. So 
the test is really focus about the priority of jobs, not about which pool is 
processing it. 
This change is similar to make the minimal threads number of short compaction 
pool  to be 2 which will also break the test without manually blocking one of 
them.

> Large compaction queue should steal from small compaction queue when idle

> If you tune compaction threads so that a server is never over commited when 
> large and small compaction threads are busy then it should be possible to 
> have the large compactions steal work.
