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 how the batch part does it (here the `LocalExecutor` has a field `taskManagerNumSlots` which can be set). Besides that, looks good to merge.
