Dear all
 
I have a Cassandra cluster = with 2 nodes.
I was trying to increase the = replication factor of keyspace in Cassandra to 2. I did the following = steps:
UPDATE KEYSPACE demo WITH = strategy_options =3D {DC1:2,DC2:2}; on both the = nodes
Then I ran = the nodetool repair on both the nodes
Then I ran my Hector code to count the = number of rows and columns in the database.
I get the following error: Unavailable = Exception
Also when I = run the command
./nodetool = =96h ip_address ring
