Summary: Extend HivePreFilteringRule to cover more cases
Key: HIVE-12044
URL: https://issues.apache.org/jira/browse/HIVE-12044
Project: Hive
Issue Type: Bug
Components: CBO
Affects Versions: 2.0.0
Reporter: Jesus Camacho Rodriguez
Assignee: Jesus Camacho Rodriguez
The logic of traversing expressions (ExtractCommonOperands) is not recursive
and misses many of the use cases.
Also check for comparison need to take in to account functions (ex: ((x+y)=10
and z=1) or ((x+y)=10 and z=2) ).
