When your computation is done, it is better to stop your cluster to avoid additional cost. To stop your clusters, execute the following commands from your local machine:
$ SPARK_HOME/ec2/spark-ec2 --region=<ec2-region> stop <cluster-name>
For our case, it would be the following:
$ SPARK_HOME/ec2/spark-ec2 --region=eu-west-1 stop ec2-spark-cluster-1
To restart the cluster later on, execute the following command:
$ SPARK_HOME/ec2/spark-ec2 -i <key-file> --region=<ec2-region> start <cluster-name>
For our case, it will be something like the following:
$ SPARK_HOME/ec2/spark-ec2 --identity-file=/usr/local/key/-key-pair.pem --region=eu-west-1 start ec2-spark-cluster-1
Finally, to terminate ...
