bharath v commented on HIVE-1643:
---------------------------------
New patch attached. Works also for nested predicates! Implemented new methods
for analyzing predicates rather than depending on IPA ! These methods work more
accurately for HBase specific filter pushdowns! Added some test cases too !
> support range scans and non-key columns in HBase filter pushdown

> 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.
