>                 Key: FLINK-4408
>                 URL: https://issues.apache.org/jira/browse/FLINK-4408
>             Project: Flink
>          Issue Type: Sub-task
>          Components: Cluster Management
>            Reporter: Xiaogang Shi

> Once granted the leadership, JM will start to execute the job.
> Most code remains the same except that 
> (1) In old implementation where JM manages the execution of multiple jobs, JM has to
load all submitted JobGraphs from SubmittedJobGraphStore and recover them. Now that the components
creating JM will be responsible for the recovery of JobGraphs, JM will be created with submitted/recovered
JobGraph, without the need to load the JobGraph.
> (2) JM should not rely on Akka to listen on the updates of JobStatus and Execution.
