             Project: Cassandra
          Issue Type: Bug

            Reporter: N Sujit Kumar


Hi Team,

We had 2 node Cassandra cluster with replication factor of 1 and num_token value of 256 each. After we've added 2 more nodes to that 2 node cluster. 

But after adding 2 new nodes the cluster was not balance properly. Data did not distributed to new nodes.

After i ran nodetool repair on all nodes but our keyspace not get affected because of Replication Factor as 1.

So I have changed RF to 2 and ran nodetool repair, then our keyspace got effected with repair.

*But after that issue is we were not getting complete results with queries.*

*e.g. we had 4 months of data loaded into our tables earlier, but when we query on the tables after adding new nodes with date range we were getting data for some dates, {color:#de350b}not getting data for some dates{color}.* 

Can you please help us what needs to be done for adding new nodes to the Apache Cassandra Cluster?
