Subject: Cassandra not retrieving the complete data on 2 nodes

Dear all

I was originally having a 1 node cluster. Then I added one more node to it with initial token
configured appropriately. Now when I run my queries I am not getting all my data ie all columns.

Output on 2 nodes
Time taken to retrieve columns 43707 of key range is 1276
Time taken to retrieve columns 2084199 of all tickers is 54334
Time taken to count is 230776
Total number of rows in the database are 183
Total number of columns in the database are 7903753

Output on 1 node
Time taken to retrieve columns 43707 of key range is 767
Time taken to retrieve columns 3855552 of all tickers is 52793
Time taken to count is 268135
Total number of rows in the database are 396
Total number of columns in the database are 16316426

Please help me. Where is my data going or how should I retrieve it.

Thanks and Regards
