Sean Owen resolved SPARK-6935.
------------------------------
Resolution: Not A Problem
Ah right, it is already there as --master-instance-type
> 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
> Labels: easyfix
> Original Estimate: 24h
> Remaining Estimate: 24h
>
> 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> # applies to slaves
> only
> --instance-type-master=<instance_type> # applies to master
> only
> --instance-type=<instance_type> # default, applies to
> both
> # in real world
> sh spark-ec2 --instance-type-slave=r3.2xlarge --instance-type-master=c3.xlarge
> {code}
