Till Rohrmann updated MAHOUT-1570:
----------------------------------
Description:
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.
was:
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.
