Review comment:
Yeah actually I just read decompiled code of `Utils.getUGI()` (missed to
read comment in source) and didn't indicate the intention - let other
application be able to pass it. Yes I agree it's not needed in Spark side, and
it would be weird `HADOOP_USER_NAME` is only used here and undocumented. Thanks
for explaining!
