Yu Ishikawa commented on SPARK-6935:
------------------------------------
That's reasonable. Spark v1.3.0 has the `\-\-master-instance-type` option, not
`\-\-instance-type-master`. Do you mean that we should add other new options,
deprecating the current option?
And I feel like refactoring the script because it has many functions with long
lines. So it is a little hard to maintain the source code. Just a comment.
> spark/spark-ec2.py add parameters to give different instance types for master
> and slaves

> Project: Spark
> Issue Type: Improvement
> Components: EC2

> 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}
