Andrew Palumbo updated MAHOUT-1570:
-----------------------------------
Labels: DSL flink scala (was: )
> Adding support for Stratosphere 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
> Labels: DSL, flink, scala
>
> 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.
