Hi,

Can somebody please share me details about setting up of EC2snitch in AWS
single region which has availability zone 1a and 1b? I am using Cassandra
version 1.2.19 in the setup.

I would appreciate your help.

Regards,

Kaushal

Arun sirimalla: Hi Kaushal, Here is the reference, http://docs.datastax.com/en/cassandra/2.0/cassandra/architecture/architectureSnitchEC2_t.html -- Arun Senior Hadoop/Cassandra Engineer Cloudwick 2014 Data Impact Award Winner (Cloudera) http://www.cloudera.com/content/cloudera/en/campaign/data-impact-awards.html
Jared Biel: It's pretty straightforward - there is documentation here . Simply set endpoint_snitch: Ec2Snitch in cassandra.yaml when creating the cluster and create keyspaces with the necessary NetworkTopologyStrategy. The only real gotcha that I've run into is that the "datacenter" (cassandra) and "regions" (AWS) match up 1:1 except for us-east-1 (it's just "us-east " in the Ec2Snitch.) Below are some examples that specify that data for that keyspace will be present on 3 nodes. See consistency
Ali Akhtar: What details specifically do you mean? I wrote this bash script which is what I've been using for installing cassandra 2.0.xx on AWS: https://gist.github.com/aliakhtar/3649e412787034156cbb
