-------------------------------------------
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}
