             Summary: spark_ec2.py ssh failure retry handling not always appropriate
                 Key: SPARK-5851
                 URL: https://issues.apache.org/jira/browse/SPARK-5851
             Project: Spark
          Issue Type: Bug
          Components: EC2
            Reporter: Florian Verhein
            Priority: Minor



The following function doesn't distinguish between the ssh failing (e.g. presumably a connection issue) and the remote command that it executes failing (e.g. setup.sh). The latter should probably not result in a retry. 

Perhaps tries could be an argument that is set to 1 for certain usages. 

# Run a command on a host through ssh, retrying up to five times
# and then throwing an exception if ssh continues to fail.
def ssh(host, opts, command):
