Hi [~wanglijie95] , can you confirm this problem?
> Unsupportedoperation exception caused by createActualEdge error in adaptive
> batch scheduler
> -------------------------------------------------------------------------------------------
>
> Key: FLINK-26668
> URL: https://issues.apache.org/jira/browse/FLINK-26668
> Project: Flink
> Issue Type: Bug
> Components: API / DataStream
> Affects Versions: 1.15.0
> Environment:
>
> Reporter: kangTwang
> Priority: Major
> Attachments: aaa.jpg, bbb.jpg
>
>
> In the AdaptiveBatch TPC DS test, the following error messages appear when
> executing query_23a，If the upstreamnode is Calc [50], the downstreamnode is
> multipleinput [75], and they are forwardpartitioners, the parallelism is
> inconsistent, and an unsupported operationexception is thrown：
> !aaa.jpg!
> Because the error is thrown in the streamgraph stage, the specific DAG
> diagram cannot be seen. Therefore, non adaptive batch is adopted. The DAG
> diagram executed is as follows:
> !bbb.jpg!
> Check Calc [50] and find that the downstream operator is HashAggregate[51],
> not MultipleInput[75]
