B) data has a concrete syntactic form that can be displayed and understood
along with other concrete forms that guarantee to keep the same semantics in
terms of tagged data elements.  This universal tagging in the data makes a
lot of run-time schema things pretty trivial.  It also allows test data to
be written into a script or example program and allows that test data to be
processed to a concrete result without involving the cluster.

C) they keep some of the best parts of pig like group and co-group.

Things I don't like:

1) Doesn't do map-reduce for all operations yet (presumably coming).

2) Doesn't have a provision for displaying the map-reduce version of the

3) Not open source.

Does anybody else have any thoughts on this?
