----------------------------------------

@Bharath,

* Can you create a phabricator review request for this? https://cwiki.apache.org/confluence/display/Hive/PhabricatorCodeReview
* There are no test cases in your patch. Would you mind adding few?

You can first create a review request so that I continue the review. In the meanwhile you can work on tests.

> HIVE-1226 added support for WHERE rowkey=3.  We would like to support WHERE rowkey BETWEEN 10 and 20, as well as predicates on non-rowkeys (plus conjunctions etc).  Non-rowkey conditions can't be used to filter out entire ranges, but they can be used to push the per-row filter processing as far down as possible.
