Indeed a bug. This is a blocker (no work around) in some conditions so tracking it down now.

Thanks for sharing!

V0.6.0 training failed on one of our mock data sets. (Mahout: Incompatible operand geometry).
In my case it fails if a user id has purchase event, but no view event.

Input data:
Purchase (userid, itemid
A, 1
B, 3
C, 3

View:
A, 1
B, 2
C, 2

If I remove the last event from view, training fails.

If anyone want to try out RC1 of the UR with pio 0.11.0 get the `develop` branch of the UR
here: https://github.com/actionml/universal-recommender <https://github.com/actionml/universal-recommender>

pull the repo then `git checkout develop` before you build it with pio

I defaults to Spark 1.6, ES 1.7 and Scala 2.10, a UR v0.6.1 will have new build.sbt to support
other configs. It does not support ES 5 but there is a PR that is nearly complete so expect
that to be incorporated soon.
