GitHub user liyinan926 opened a pull request:
https://github.com/apache/spark/pull/265
Added support for accessing secured HDFS
Also changed the way task run so tasks always run under the user who submit
the tasks. This replaces the old approach of using a environment variable
SPARK_USER to specify the user, which is far less flexible. This eases security
management since users no longer need to open access to HDFS files under their
home directory to the user who starts the Spark cluster.
