    You are right, we can. I replaced the usage of these with the default partitioning parameters
of SAMOA several commits before, just forgot to remove their definition. I just removed it

> Apache Flink-Streaming is a new system for distributed stream processing built for unique
and flexible high level stream transformations. A Flink adapter for Samoa should be able to
translate a Samoa Task topology into Flink streaming transformations. Some of the challenges
are the compositional topology support, circle detection and their translation to Flink iterations.
