Tom White resolved HADOOP-6393.
-------------------------------
Resolution: Not A Problem
I realized that this is actually already supported as long as you launch the
master separately:
{code}
hadoop-ec2 launch-master --instance-type=c1.xlarge my-hadoop-cluster
hadoop-ec2 launch-slaves my-hadoop-cluster 10 # use the instance type set in
the configuration
{code}
> Allow master to run on larger EC2 instance

> The namenode often needs more memory, so it would be useful to allow it to be
> run on a different instance size.
