Github user mxm commented on the pull request: https://github.com/apache/flink/pull/1360#issuecomment-158334929 I think we agree that we want to set the number of task slots to the maximum parallelism instead of the default one. I'll merge this later on. --- If your project is set up

Github user tillrohrmann commented on the pull request: https://github.com/apache/flink/pull/1360#issuecomment-158052735 Yes I think so. I guess it's due to the difference that batch programs are executed using a `PlanExecutor` whereas streaming programs are directly executed by the `

Github user mxm commented on the pull request: https://github.com/apache/flink/pull/1360#issuecomment-158049463 Exactly. But that makes sense, right? If the users explicitly sets the number of task slots, we shouldn't change the number of task slots automatically. --- If your projec

Github user mxm commented on the pull request: https://github.com/apache/flink/pull/1360#issuecomment-158032582 Just checked. The batch side always uses the maximum parallelism as the number of task slots (if they are not set explicitly). Till and me actually thought differently. So t

Github user mxm commented on the pull request: https://github.com/apache/flink/pull/1360#issuecomment-158024467 Alright. I will push the original pull request version again which uses the max parallelism of all operators. Further, I will open a separate JIRA for the batch side change.

Github user mxm commented on the pull request: https://github.com/apache/flink/pull/1360#issuecomment-158020011 I would also be in favor of changing the local execution to always use the maximum specified parallelism as the number of task slots. IMHO the current behavior is not intuit

Github user mxm commented on the pull request: https://github.com/apache/flink/pull/1360#issuecomment-158009498 True. That's how it is handled on the batch side. Not sure about this behavior though. If a user sets a default parallelism but uses operators with `parallelism > defaultPar

Github user tillrohrmann commented on the pull request: https://github.com/apache/flink/pull/1360#issuecomment-157766781 I think the maximum parallelism of the job should be taken if the user has not specified a different parallelism than the default one (`-1`). I think that's also ho
