[jira] [Created] (FLINK-21403) Some tests expect to fail if parallelism cannot be met

Chesnay Schepler created FLINK-21403:
----------------------------------------

             Summary: Some tests expect to fail if parallelism cannot be met
                 Key: FLINK-21403
                 URL: https://issues.apache.org/jira/browse/FLINK-21403
             Project: Flink
          Issue Type: Sub-task
          Components: Tests
    Affects Versions: 1.13.0
            Reporter: Chesnay Schepler


The TableSinkITCase contains tests to ensure that a job submission fails if the parallelism is exceedingly large.
The declarative scheduler is having none of that and just downscales the job to make it runnable, causing the tests to fail.

It may make sense to add a switch to disable downscaling (until we have a proper range of accepted parallelism), as this issue will also affect e2e tests where the start of processes takes so long that the resource timeout fires and the job is run with a lower parallelism, which the tests don't handle well.
