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

             Summary: set maxParallelism to 1 when DataStreamSource is not isParallel
                 Key: FLINK-12816
                 URL: https://issues.apache.org/jira/browse/FLINK-12816
             Project: Flink
          Issue Type: Task
          Components: API / DataStream
    Affects Versions: 1.8.0
            Reporter: XuPingyong
             Fix For: 1.9.0


Now when DataStreamSource is not parallel, only parallelism is set to 1, maxParallelism should be also set to 1.

 

As when SingleOutputStreamOperator is not  parallel, it set not only parallelism but also maxParallelism to 1
