Subject [jira] [Created] (FLINK-6188) Some setParallelism() method can't cope with default parallelism

---------------------------------------

             Summary: Some setParallelism() method can't cope with default parallelism
                 Key: FLINK-6188
                 URL: https://issues.apache.org/jira/browse/FLINK-6188
             Project: Flink
          Issue Type: Bug
          Components: DataStream API
    Affects Versions: 1.2.1
            Reporter: Aljoscha Krettek
             Fix For: 1.2.1


Recent changes done for FLINK-5808 move default parallelism manifestation from eager to lazy,
that is, the parallelism of operations that don't have an explicit parallelism is only set
when generating the JobGraph. Some `setParallelism()` calls, such as `SingleOutputStreamOperator.setParallelism()`
cannot deal with the fact that the parallelism of an operation might be {{-1}} (which indicates
that it should take the default parallelism when generating the JobGraph).

We should either revert the changes that fixed another user-facing bug for version 1.2.1 or
fix the methods.
