Subject Re: Launching HBase from source code to test the changes.
Date Sun, 28 Aug 2011 12:46:09 GMT
Hi,

Thanks for your reply. So I was able to figure out the problem when I looked
at the hadoop logs. Apparently there was mismatch between the namespace and
datanode ids after I had changed the version of HBase I was using. I was
able to resolve it by reformating the hdfs.

Thanks again
Anurag
