[jira] [Created] (FLINK-9537) JobManager isolation in session mode

Till Rohrmann created FLINK-9537:
------------------------------------

             Summary: JobManager isolation in session mode
                 Key: FLINK-9537
                 URL: https://issues.apache.org/jira/browse/FLINK-9537
             Project: Flink
          Issue Type: Improvement
          Components: Distributed Coordination
    Affects Versions: 1.5.0, 1.6.0
            Reporter: Till Rohrmann


Currently, all {{JobManagers}} are executed in the same process which also runs the {{Dispatcher}} component when using the session mode. This is problematic, since the {{JobManager}} also executes user code. Consequently, a bug in a single Flink job can cause the failure of the other {{JobManagers}} running in the same process. In order to avoid this we should add the functionality to run each {{JobManager}} in its own process.
