Jie Huang updated HBASE-2730:
-----------------------------

    Attachment: hbase-2730-0_94_0.patch

Thanks for the comments. Two modifications:
1. Enable the queue dump by default. We can also disable it by set "hbase.regionserver.servlet.show.queuedump"
as false.
2. Add the queue dump into debug dump

> Would be nice to be able to see the contents of the various work queues - eg to know
what regions are pending compaction/split/flush/etc. This is handy for debugging why a region
might be blocked, etc.
