Description

runAsSparkUser enable classes using hadoop library to change an active user to spark User, however in Mesos environment, because the function calls before running within JNI, runAsSparkUser doesn't affect anything, and meaningless code. fix the Appropriate scope of function and remove meaningless code. That's a bug because of running program incorrectly. That's related to SPARK-3223 but setting framework user is not perfect solution in my tests.
