Dear all,
I had a 1 node cluster of Cassandra. Then I added one more node to it and started Cassandra
on it. I got the following error:
INFO 12:44:49,588 Loading persisted ring state
ERROR 12:44:49,613 Exception in thread Thread[COMMIT-LOG-ALLOCATOR,5,main]

Please tell me what is the reason for this error and how should I rectify it.
Thanks and Regards
