------------------------------------

             Summary: Standalone mode can't access secure HDFS anymore
                 Key: SPARK-2541
                 URL: https://issues.apache.org/jira/browse/SPARK-2541
             Project: Spark
          Issue Type: Bug
          Components: Deploy
    Affects Versions: 1.0.0, 1.0.1
            Reporter: Thomas Graves


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.
