---------------------------------------
Summary: Enhance spark-ec2 to be able to add and remove slaves to
an existing cluster
Key: SPARK-2008
URL: https://issues.apache.org/jira/browse/SPARK-2008
Project: Spark
Issue Type: New Feature
Components: EC2
Affects Versions: 1.0.0
Reporter: Nicholas Chammas
Per [the discussion

I would like to be able to use spark-ec2 to launch new slaves and add them to
an existing, running cluster. Similarly, I would also like to remove slaves
from an existing cluster.
Use cases include:
* Oh snap, I sized my cluster incorrectly. Let me add/remove some slaves.
* During scheduled batch processing, I want to add some new slaves, perhaps on
spot instances. When that processing is done, I want to kill them. (Cruel, I
know.)
I gather this is not possible at the moment. spark-ec2 appears to be able to
launch new slaves for an existing cluster only if the master is stopped. I also
do not see any ability to remove slaves from a cluster.
