Subject unbalanced ring
Date Mon, 26 Mar 2012 14:07:13 GMT
Hi!
I created Amazon ring using datastax image and started filling the db.
The cluster seems un-balanced.

nodetool ring returns:
Address         DC          Rack        Status State   Load            Owns
   Token

Any idea what is the cause?
I am running similar code on local ring and it is balanced.

How can I fix this?

Thanks,
