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