Is spark-ec2 supposed to run normally from Windows (e.g. to launch a cluster)?
I ask because I don’t see mention of Windows anywhere in relation to spark-ec2, and there is an open PR <https://github.com/apache/spark/pull/4162/files#diff-ada66bbeb2f1327b508232ef6c3805a5R358> that checks file permissions, and I’m not sure if we need to care about how permission masks show up on Windows vs. Unix systems.
