> 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.
