Matt McCline created HIVE-8272:
----------------------------------
Summary: Query with particular decimal expression causes NPE
during execution initialization
Key: HIVE-8272
URL: https://issues.apache.org/jira/browse/HIVE-8272
Project: Hive
Issue Type: Bug
Components: Logical Optimizer, Physical Optimizer
Reporter: Matt McCline
Priority: Critical
Fix For: 0.14.0
Query:
{code}
select
cast(sum(dc)*100 as decimal(11,3)) as c1
from somedecimaltable
order by c1
limit 100;
{code}
Fails during execution initialization due to *null* ExprNodeDesc.
Noticed while trying to simplify a Vectorization issue and realized it was a
more general issue.
