Subject [jira] [Created] (IMPALA-5440) Add planner tests with extreme statistics values.

Alexander Behm created IMPALA-5440:
--------------------------------------

             Summary: Add planner tests with extreme statistics values.
                 Key: IMPALA-5440
                 URL: https://issues.apache.org/jira/browse/IMPALA-5440
             Project: IMPALA
          Issue Type: Test
          Components: Infrastructure
    Affects Versions: Impala 2.7.0, Impala 2.8.0, Impala 2.9.0
            Reporter: Alexander Behm


We should add planner tests that exercise the cardinality and resource estimation logic with
extreme values to make sure those are handled appropriately (e.g. when there is overflow).
The tests should help find and guard against issues like IMPALA-5282.
