I am having issues setting up my spark environment to read from a kerberized HDFS file location.
At the moment I have tried to do the following: def ugiDoAs[T](ugi: Option[UserGroupInformation])(code: => T) = ugi match { case None => code case Some(u) => u.doAs(new PrivilegedExceptionAction[T] { override def run(): T = code }) } val sparkConf = defaultSparkConf.setAppName("file-test").setMaster("yarn-client") val sc = ugiDoAs(ugi) {new SparkContext(conf)} val file = sc.textFile("path") It fails at the point of creating the Spark Context, with the following error: Exception in thread "main" org.apache.hadoop.security.AccessControlException: SIMPLE authentication is not enabled.

I know that spark needs to be in Yarn mode to be able to make it work, but the login method does not seem to be working in this respect. Although I know that the User Group Information (ugi) object is valid as I have used it to connect to ZK in the same object and HBase. Thanks!
