             Summary: spark/spark-ec2.py add parameters to give different instance types for master and slaves
                 Key: SPARK-6935
                 URL: https://issues.apache.org/jira/browse/SPARK-6935
             Project: Spark
          Issue Type: Improvement
          Components: EC2
    Affects Versions: 1.3.0
            Reporter: Oleksii Mandrychenko
            Priority: Minor


I want to start a cluster where I give beefy AWS instances to slaves, such as memory-optimised R3, but master is not really performing much number crunching work. So it is a waste to allocate a powerful instance for master, where a regular one would suffice.

Suggested syntax:

{code}
sh spark-ec2 --instance-type-slave=<instance_type> 
             --instance-type-master=<instance_type>

# in real world
sh spark-ec2 --instance-type-slave=r3.2xlarge --instance-type-master=c3.xlarge
{code}
