Description

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.
