Description

The TableSinkITCase contains tests to ensure that a job submission fails if the parallelism is exceedingly large.
The adaptive 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.
