Tool to run major compaction on catalog regions when hbase is shutdown
----------------------------------------------------------------------

                 Key: HBASE-1662
                 URL: https://issues.apache.org/jira/browse/HBASE-1662
             Project: Hadoop HBase
          Issue Type: New Feature
            Reporter: stack
             Fix For: 0.20.0


We need this tool in 0.19.  Mildly useful in 0.20.

To migrate (HBASE-1215), all tables need to have had a major compaction done.    This should
work fine for user-space tables as long as no writes coming in.  With catalog tables its a
little different.  They will always have some edits and its tricky getting cluster to go down
with it flushing -- adding more files to region.

Am adding an HRegion#main that will list catalog region content by default -- may help debugging
-- and then if you add the major_compact option, will major_compact passed region.
