---------------------------------------

[~till.rohrmann] Is the Jira description still valid? It still has references to old Stratosphere, please feel free to update.

> With the finalized abstraction of logical Mahout DSL plans from the backend operations (MAHOUT-1529), it should be possible to integrate further backends for the Mahout DSL.
> I like to evaluate to what extent this can already be done for Stratosphere and what can be done to solve possibly occuring problems. 
> The biggest difference between Spark and Stratosphere at the moment is probably the incremental rollout of plans, which is triggered by Spark's actions and which is not supported by Stratosphere yet. However, the Stratosphere team 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.
> Thus, this work shall rather be considered as a proof of concept than a strongly efficient implementation and has the purpose to evaluate where the logical plan abstraction might be refined in order to support different backends.
