Subject Re: why the table not balance when i start a new tablet server
Date Sun, 21 Dec 2014 05:15:23 GMT
Like Eric said, check the master_*.debug.log (grep for 'balance' will 
probably show a reason why). Also, you should be able to see the same 
warning on the Accumulo monitor "Recent Logs" page.

If you still can't find anything wrong looking at the logs, just restart 
the master process as a quick-fix.
