-------------------------------------

             Summary: Parquet min/max should detect invalid min/max values
                 Key: IMPALA-5276
                 URL: https://issues.apache.org/jira/browse/IMPALA-5276
             Project: IMPALA
          Issue Type: Bug
          Components: Backend
    Affects Versions: Impala 2.9.0
            Reporter: Joe McDonnell
            Assignee: Joe McDonnell


When evaluating min/max predicates on Parquet, the code should verify that the Parquet stats
meet basic criteria. Specifically, min <= max and any other hardening that would be useful
for min/max (if there are any values that are invalid or if min is set without max, etc).
