Hello,
 
thank you very much for your reply.
 
I want to ask another question:
for an already existed keyspace,  can I change the number of replicas in it's REPLICATION option?
If so,  do  I need to restart the whole cluster?
 
Thanaks in advance.

Hello,

No you don't need to. Check this out: http://www.datastax.com/documentation/cassandra/2.0/webhelp/index.html#cassandra/operations/ops_add_node_to_cluster_t.html

Hi all,
 
I want to ask a basic question: To add a new node to Cassandra system, do I need to restart the Cassandra system?
 
thanks
