Thomas Graves commented on SPARK-2541:
--------------------------------------
I'm fine with reopening this. Ideally we would officially support security in
standalone mode but it appears that hasn't happened so I think fixing this lets
it work.
> 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
> Attachments: SPARK-2541-partial.patch

>
> 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.
