Subject [GitHub] spark pull request: [SPARK-787] Add S3 configuration parameters to...
Date Mon, 08 Sep 2014 17:22:32 GMT

    @JoshRosen Yes, the credentials could be supplied in boto specific config files, but if
they're not there the spark_ec2 script will look in the env variables, and error out with
a message - see https://github.com/apache/spark/blob/master/ec2/spark_ec2.py#L174
    So this PR will not work for those who have the credentials in boto configs, but at least
it doesn't break anything.
    
    As far as security, EMR uses essentially the same method for transferring credentials
to the cluster nodes, so I don't think there are any additional concerns.
