Hi Jack, I'm supposing you are actually referring to JobMaster by the term JobManager in your context (the JobManager referred in the doc is usually a collection of components that comprises the Dispatcher, ResourceManager, and a set of one-per-job JobMasters).
The jobmaster's lifecycle is bound to the job's lifecycle, so yes, after the job is finished, its jobmaster will be shutdown. Taskmanagers, on the other hand, are shared among jobs. Hope that helps.

When the dispatcher receives a job, the dispatcher will start a JobManager. After the job is finished, will the JobManager be shut down? For the TaskManager, after the job is finished, will the TaskManager be shut down? Or is the TaskManager shared among all the tasks? Thanks. Jack
