> With the finalized abstraction of the Mahout DSL plans from the backend operations (MAHOUT-1529), it should be possible to integrate further backends for the Mahout DSL. Apache Flink would be a suitable candidate to act as a good execution backend. 
> With respect to the implementation, the biggest difference between Spark and Flink at the moment is probably the incremental rollout of plans, which is triggered by Spark's actions and which is not supported by Flink yet. However, the Flink community is working on this issue. For the moment, it should be possible to circumvent this problem by writing intermediate results required by an action to HDFS and reading from there.
