-----------------------------------

             Summary: TaskManager shell scripts restart JVMs on process failures
                 Key: FLINK-1812
                 URL: https://issues.apache.org/jira/browse/FLINK-1812
             Project: Flink
          Issue Type: Improvement
          Components: Start-Stop Scripts
    Affects Versions: 0.9
            Reporter: Stephan Ewen


Currently, the TaskManager processes may die under certain fatal exceptions that prevent the
TaskManager to proceed.
Most of those problems can be fixed by a clean process (JVM) restart.

We can make the system more resilient by changing the {{taskmanager.sh}} bash script to restart
the processes upon a certain exit code. 

The TaskManager returns that exit code whenever it kills itself due to a problem that requires
a clean JVM.
