[jira] [Created] (FLINK-22135) Test the adaptive scheduler

Till Rohrmann created FLINK-22135:
-------------------------------------

             Summary: Test the adaptive scheduler
                 Key: FLINK-22135
                 URL: https://issues.apache.org/jira/browse/FLINK-22135
             Project: Flink
          Issue Type: Task
          Components: Runtime / Coordination
    Affects Versions: 1.13.0
            Reporter: Till Rohrmann
             Fix For: 1.13.0


With FLINK-21075, we introduced a new scheduler type which first waits for resources before deciding on the actual parallelism. This allows to continue executing a job even if the cluster loses a {{TaskManager}} permanently. We should test that this feature works as described by its documentation [1] (w/o using the reactive mode).
