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

             Summary: Introduce RECONCILIATING state in ExecutionGraph
                 Key: FLINK-4912
                 URL: https://issues.apache.org/jira/browse/FLINK-4912
             Project: Flink
          Issue Type: Sub-task
          Components: Distributed Coordination
            Reporter: Stephan Ewen


This is part of the non-disruptive JobManager failure recovery.

I suggest to add a JobStatus and ExecutionState {{RECONCILING}}.
If a job is started on a that JobManager for master recovery (tbd how to determine that) the {{ExecutionGraph}} and the {{Execution}}s start in the reconciling state.

From {{RECONCILING}}, tasks can go to {{RUNNING}} (execution reconciled with TaskManager) or to {{FAILED}}.
