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
