Dmitriy Lyubimov commented on MAHOUT-1489:
------------------------------------------

well the dangerous code is the mahout shell modifications. 

Since there's a lot of code there devoted (in fairly inconsistent way) figuring out Hadoop setup and its classpath, and spark commands now need to make sure that doesn't happen, while adding spark jars... it becomes somewhat kludgy and may break MR things. I so far don't see evidence of that happening but i am not verifying mahout MR commands all the way either.

> Build an interactive shell /scripting (just like spark shell). Something very similar in R interactive/script runner mode.
