AWS cassandra nodes cloning

Question

I have built a single cassandra node on AWS and its working fine. We want to build 5 more of it so we have cloned the first one into 5 other cassandra servers. I would like to know what all the changes we possibly need to make so that they will run into 5 new cassandra servers.

1) delete all the data in data directories, saved_caches and commitlog 2) update cassandra.yaml file with listen, broadcast and rpc_addresses. 3) what change should we make at system level like hostname or gateway or any other things for the new nodes????? Kindly suggest these, i don't have much knowledge of system administration. 4) I have stopped the original node cassandra service and ds agent service before taking the clones.

please add any other things i need to change to make the cluster work with new 5 nodes.

Many Thanks.

Datastax has a guide for planning an Amazon EC2 cluster . After reviewing the Datastax guide, make sure you configure the cassandra.yaml file with the correct options. If all of the nodes will have duplicate directory structures you can use the same cassandra.yaml file on each node. Note that making changes to the cassandra.yaml will require a restart.

For more information on configuration of the nodes in a single data center see " Initializing a multiple node cluster in a single data center ." For multiple data centers see " Initializing a multiple node cluster, multiple data centers ."

If you follow the steps outlined in the documentation and guides you should be able to easily add new nodes to your instance.
