Hi @PieterJanVanAeken,
I think it is fine to just update the test file that your PR touches and
port this one to the `collect()` approach. Then we don't need to wait for the
other tests to be fixed and get this PR in. Have a look at the `ReduceITCase`
in `flink-tests` which uses the `collect()` pattern.
