> In spark 0.9.x you could access secure HDFS from Standalone deploy, that doesn't work in 1.X anymore. 
> It looks like the issues is in SparkHadoopUtil.runAsSparkUser.  Previously it wouldn't do the doAs if the currentUser == user.  Not sure how it affects when the daemons run as a super user but SPARK_USER is set to someone else.
