Github user dlyubimov commented on the pull request:

    Ok here is what i suggest.
    
    Since the code is still a bit raw (in a sense of passing tests), let's
    indeed pull Alexey's work into a dev mahout branch and then create a new
    request to merge to master to track merge conflicts (github will quick to
    note those).
    
    The reason is that i proably may want to do some small changes to it so the
    assumption is that it would be more visible (and easier for me:) to do it
    that way than to actually send a PR to Alexey's github project to enter
    changes into the pr.
    
    If ti is ok, i can do it.

> Adding support for Apache Flink as a backend for the Mahout DSL
> ---------------------------------------------------------------

>                 Key: MAHOUT-1570
>                 URL: https://issues.apache.org/jira/browse/MAHOUT-1570
>             Project: Mahout
>          Issue Type: Improvement
>            Reporter: Till Rohrmann
>            Assignee: Alexey Grigorev

> 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.
