[jira] [Created] (SPARK-5342) Allow long running Spark apps to run on secure YARN/HDFS

Hari Shreedharan created SPARK-5342:
---------------------------------------

             Summary: Allow long running Spark apps to run on secure YARN/HDFS
                 Key: SPARK-5342
                 URL: https://issues.apache.org/jira/browse/SPARK-5342
             Project: Spark
          Issue Type: Bug
          Components: YARN
    Affects Versions: 1.2.0
            Reporter: Hari Shreedharan


Currently, Spark apps cannot write to HDFS after the delegation tokens reach their expiry, which maxes out at 7 days. We must find a way to ensure that we can run applications for longer - for example, spark streaming apps are expected to run forever.
