5.5. Known Issues for Oozie

  • BUG-10177: Oozie workflows that contain Hive queries which run mapreduce jobs fail on secure clusters.

    Problem: There is a bug in Hive (HIVE-5618) where delegation tokens are requested for a user who does not have the ability to do so (such as when it is launched from Oozie).

    Workaround: Set the configuration parameter before any query statements in the script file are launched as part of the Hive action

    hive.server2.enable.doAs = false

    This parameter instructs Hive not to request delegation tokens, which should not be done when running under Oozie.

  • BUG-9671: Oozie reports the job as failed when the app and job completed successfully when RM is restarted multiple times

    Problem: From the oozie log
