[jira] [Created] (FLINK-21136) Reactive Mode: Adjust timeout behavior in declarative scheduler

--------------------------------------

             Summary: Reactive Mode: Adjust timeout behavior in declarative scheduler
                 Key: FLINK-21136
                 URL: https://issues.apache.org/jira/browse/FLINK-21136
             Project: Flink
          Issue Type: Sub-task
          Components: Runtime / Coordination
            Reporter: Robert Metzger
             Fix For: 1.13.0


The FLIP states the following timeout and resource registration behavior:

On initial startup, the declarative scheduler will wait indefinitely for TaskManagers to show up. Once there are enough TaskManagers available to start the job, and the set of resources is stable (see FLIP-160 for a definition), the job will start running.

Once the job has started running, and a TaskManager is lost, it will wait for 10 seconds for the TaskManager to re-appear. Otherwise, the job will be scheduled again with the available resources. If no TaskManagers are available anymore, the declarative scheduler will wait indefinitely again for new resources.
