Jonathan Gray commented on HBASE-7:
-----------------------------------

FYI, there is an existing call in HRegionInterface that can be used:
{noformat}public HRegionInfo[] getRegionsAssignment() throws 
IOException;{noformat}
Currently that's being used during master failover though this may change with 
the zk/master stuff underway, I think it will still make sense to retain this 
call for debugging/fsck.

While on the subject, there's also another call in HRI:
{noformat}public HRegion [] getOnlineRegionsAsArray();{noformat}
This doesn't appear to be used anywhere except in 4 commented-out tests in 
TestHBaseAdmin :)  Unless there are objections, I'm going to remove it while 
doing other cleanup in master/client/rs comm.
