Hi all, Recently I am reading source code of Flink. There are both JobManager and JobMaster in flink-runtime project. And JobManagerRunner interface says it is a runner which executes a JobMaster. So how to distinguish the two concepts? Is JobMaster a subset of JobManager? Or JobMaster is a new version which is going to replace the function of JobManager? Or the two roles are different?
Thank you! Weizheng
