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 `StreamExecutionEnvironment`. Consequently, there is no direct way of specifying the number of task slots for the used `LocalFlinkMiniCluster` other than via the parallelism of the job or the default parallelism.
