[WIP] SPARK-1676: Cache Hadoop UGIs by default to prevent FileSystem leak
Move the doAs in Executor higher up so that we only have 1 ugi and aren't leaking filesystems.
Fix spark on yarn to work when the cluster is running as user "yarn" but the clients are launched as the user and want to read/write to hdfs as the user.
Note this hasn't been fully tested yet. Need to test in standalone mode.
Putting this up for people to look at and possibly test. I don't have access to a mesos cluster.
This is alternative to https://github.com/apache/spark/pull/607
