predicate pushdown fails if all columns are not selected
--------------------------------------------------------

                 Key: HIVE-497
                 URL: https://issues.apache.org/jira/browse/HIVE-497
             Project: Hadoop Hive
          Issue Type: Bug
          Components: Query Processor
    Affects Versions: 0.4.0
            Reporter: Prasad Chakka
             Fix For: 0.4.0


predicate pushdown seems to fail in some scenarios... it is ok if all the columns are selected.

create table ppda(a string, b string);
select a from ppda where ppda.a > 10; --> fails
select b from ppda where ppda.a > 10; --> ok
select * from ppda where ppda.a > 10; --> ok
select b from appd where appd.b > 10 and appd.a > 20; --> ok
