Fix Version/s: (was: 1.10.0)
Resolution: Duplicate
I'm closing this as a duplicate because the underlying reason does indeed seem
to be the same as for FLINK-14834

> This change made the test flaky:
> https://github.com/apache/flink/commit/749965348170e4608ff2a23c9617f67b8c341df5.
> It changes the job to have two sources instead of one which, under normal
> circumstances, requires too many slots to run and therefore the job will fail.
> The setup of this test is very intricate, we configure YARN to have two
> NodeManagers with 2500mb memory each:
> https://github.com/apache/flink/blob/413a77157caf25dbbfb8b0caaf2c9e12c7374d98/flink-end-to-end-tests/test-scripts/docker-hadoop-secure-cluster/config/yarn-site.xml#L39.
> We run the job with parallelism 3 and configure Flink to use 1000mb as
> TaskManager memory and 1000mb of JobManager memory. This means that the job
> fits into the YARN memory budget but more TaskManagers would not fit. We also
> don't simply increase the YARN resources because we want the Flink job to use
> TMs on different NMs because we had a bug where Kerberos config file shipping
> was not working correctly but the bug was not materialising if all TMs where
> on the same NM.
