Subject Re: Failed to create /hbase.... KeeperErrorCode = ConnectionLoss for /hbase
Date Fri, 02 Apr 2010 12:06:53 GMT
HI Ted Yu,
                     I cleaned the stuff you mentioned.  Still the problem
exists.
Cant able to stop the Master of hbase. Manually need to kill the Master. :-(
while stopping using the ./stophbase

I see the Master log files like
