Satish Subhashrao Saley created OOZIE-2581:
----------------------------------------------

             Summary: Oozie should reset SecurityManager in finally block
                 Key: OOZIE-2581
                 URL: https://issues.apache.org/jira/browse/OOZIE-2581
             Project: Oozie
          Issue Type: Bug
            Reporter: Satish Subhashrao Saley
            Assignee: Satish Subhashrao Saley


[~jlowe] found lot of lingering oozie launcher AMs which hung around 10 mins after successful completion and then jvm killed due to timeout. This happens when user code launches non-daemon threads, but mapreduce code does a System.exit() to avoid this from happening. Oozie does need the LauncherSecurityManager to capture exit codes when user applications do System.exit() . But it should reset it back to the originial security manager in the finally block so that AM code can proceed as expected in uber mode.
