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

             Summary: PartitionPruner doesn't handle top level constant expression correctly
                 Key: HIVE-6934
                 URL: https://issues.apache.org/jira/browse/HIVE-6934
             Project: Hive
          Issue Type: Bug
            Reporter: Harish Butani


You hit this error indirectly, because how we handle invalid constant comparisons. Consider:
{code}
create table x(key int, value string) partitioned by (dt int, ts string);

-- both these queries hit this issue
select * from x where key = 'abc';
select * from x where dt = 'abc';

-- the issue is the comparison get converted to the constant false
-- and the PartitionPruner doesn't handle top level constant exprs corrcetly
{code}

Thanks to [~hsubramaniyan] for uncovering this as part of adding tests for HIVE-5376
