> A hotfix part of FLINK-14405 actually breaks setting the parallelism to its
> default value for datastream sources, i.e. using value {{-1}}. This is
> because of a small typo: instead of
> {code:java}
> OperatorValidationUtils.validateParallelism(parallelism, isParallel); {code}
> this is called in
> org.apache.flink.streaming.api.datastream.DataStreamSource#setParallelism:
> {code:java}
> OperatorValidationUtils.validateMaxParallelism(parallelism, isParallel);
> {code}
