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

             Summary: ExecutionGraph use FailoverCoordinator to manage the failover of execution vertexes
                 Key: FLINK-5869
                 URL: https://issues.apache.org/jira/browse/FLINK-5869
             Project: Flink
          Issue Type: Sub-task
          Components: JobManager
            Reporter: shuai.xu
            Assignee: shuai.xu


Execution graph doesn't manage the failover of executions. It only care for the state of the whole job, which is CREATED, RUNNING, FAILED, FINISHED, or SUSPEND. 
For execution failure, it will notice the FailoverCoordinator to do failover.
It only record the finished job vertex and changes to FINISHED after all vertexes finished.
It will change to final fail if restart strategy fail or meet unrecoverable exceptions.
