Subject [GitHub] spark pull request: SPARK-1004. PySpark on YARN
Date Mon, 28 Apr 2014 18:07:05 GMT
Github user andrewor14 commented on the pull request:
    @sryza We dug around a little more and realized it's a file permissions issue. On the
CDH cluster, if I ran the application as the user `ubuntu` then it fails. However, if we ran
the application as `root`, then it succeeds. This is because the jar in the file cache on
the executor nodes have very restrictive permissions (`-r-x------  1 yarn`). Instead of throwing
a message about permissions, it simply says `No module named pyspark`.
