--------------------------------
Summary: Stats annotation fails to evaluation constant expressions
in filter operator
Key: HIVE-7491
URL: https://issues.apache.org/jira/browse/HIVE-7491
Project: Hive
Issue Type: Sub-task
Affects Versions: 0.14.0
Reporter: Prasanth J
Assignee: Prasanth J
HIVE-5369 added stats annotation to operator plan. The filter operator
evaluates all expression node descriptors and applies rules. It always returns
0 for constant expressions like 'select * from table where true' or 'select *
from table where true=true' etc.
