Hi,

You don't need to restart for that either. Check this out:

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.

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
