Dmitriy Lyubimov commented on MAHOUT-1490:
------------------------------------------
Just so we are clear, i don't see much value in that issue any longer. Whatever
happens here, seems to be a dupe of ongoing efforts elsewhere.
(1) MLI -- well this has not been moving anywhere for past year, at least not
publicly, and the approach, honestly, is not what i've been thinking in terms
lf DSL for data frames.
But:
(2) (Spark) 1.0 and 1.1 made a big progress in terms of Spark QL, and in
particular, _language-integrated QL_, which is very close to my idea about DF
DSL;
(3) There's a new project, DDF (distributed data frames) on Spark, which is
sounds awfully close in ideas too.
So in my pragmatical view, any further work on this issue will just duplicate
(2) and (3), and therefore is of much pragmatical sense (especially given (2)
and (3) works in Spark environment direclty, i.e. can co-exist with Mahout
Spark bindings literally elbow to elbow). My professional strategic position is
now re-oriented on expectation of maturation of either (2) or (3), given they
are receiving much more backing than this issue will likely ever have. So i
suggest the Mahout community just to abandon this effort, it is in all
likelihood just a waste of time. For people who are interested in this
capability in conjunction with Scala bindings, i'd rather recommend join the
forces with either (2) and (3) and perhaps bring them to a faster fruition.
