Subject Re: Java client connection to HBase 0.20.1 problem
Date Wed, 04 Nov 2009 19:37:41 GMT
Hi Amandeep,

Could you be a bit more specific what <ip address> and <hostname>?
Should it be something different than "127.0.1.1    ubuntu" ?

I'm rather a weak linux administrator and not filling well this area.
