Summary: Fix for statistics annotation in nested AND expressions
Key: HIVE-21928
URL: https://issues.apache.org/jira/browse/HIVE-21928
Project: Hive
Issue Type: Bug
Components: Physical Optimizer
Reporter: Jesus Camacho Rodriguez
Assignee: Jesus Camacho Rodriguez
Discovered while working on HIVE-21867. Having predicates with nested AND
expressions may result in different stats, even if predicates are basically
similar (from stats estimation standpoint).
For instance, stats for {{AND(x=5, true, true)}} are different from {{x=5}}.
