Review comment:
It's an unrelated change in a sense.
I found it when adding unit test. It's a potential unstable case since it
depends on the `StreamExecutionEnvironment.defaultLocalParallelism` which must
be not 1 in this case.
However I just found someone has fixed it yesterday. What a coincident! I
can remove it from this PR.
