On your client machine

As the root user

1. Install DSE
2. In the cassandra.yml file, ensure the datacenter and cluster match your analytics datacenter
3. In the cassandra-env.sh file add this configuration line toward the bottom JVM_OPTS="$JVM_OPTS -Dcassandra.join_ring=false" This will make your DSE node a coordinator only, it will not own any data. You can use this node to submit jobs to DSE locally without the need to know which is the master node.
4. start DSE
