------------------------------------------
Summary: Hive query optimisation creates wrong plan for predicate
pushdown with windowing function
Key: HIVE-25864
URL: https://issues.apache.org/jira/browse/HIVE-25864
Project: Hive
Issue Type: Bug
Reporter: mahesh kumar behera
Assignee: mahesh kumar behera
In case of a query with windowing function, the deterministic predicates are
pushed down below the window function. Before pushing down, the predicate is
converted to refer the project operator values. But the same conversion is done
again while creating the project and thus causing wrong plan generation.
