@tnachen I'm sorry but I don't understand what you say to me. Could you
tell me the meaning of "akka execution path"? I think user info is preserved by
passing SPARK_USER environment among nodes. `runAsSparkUser` reads this
environment value and change user info to appropriate one. I don't know mesos
well internally, but `mesosExecutorDriver.run` is not running task actually.
That only initialises itself for communicating with mesos master and slave.
`mesosExecutorDriver.launchTask` runs tasks actually, however, `runAsSparkUser`
doesn't influence any more because `launchTask` is not in the `runAsSparkUser`
block, If I misunderstand something, talk to me freely.
