Subject Re: Trying to run HBase in standalone and not able to access Java API! Desperate help needed.
Date Mon, 15 Jul 2013 12:40:39 GMT
You should change our hosts file to something like that:

127.0.0.1 localhost
192.168.XXX.YYY ubuntu.ubuntu-domain ubuntu

Where 192.168.XXX.YYY is your local host IP address

Can you change and retry? (Restart).
