Hi Amir,

I would recommend to post such questions to the user@flink mailing list in
the future. This list is meant for development-related topics.

I think we need more details to understand why your application is not
running properly. Can you quickly describe what your topology is doing?
Are you setting the parallelism to a value >= 1 ?
