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

             Summary: Add logic to estimate stats for BETWEEN operator
                 Key: HIVE-15029
                 URL: https://issues.apache.org/jira/browse/HIVE-15029
             Project: Hive
          Issue Type: Bug
          Components: Statistics
    Affects Versions: 2.1.0
            Reporter: Jesus Camacho Rodriguez
            Assignee: Jesus Camacho Rodriguez


Currently, BETWEEN operator is considered in the default case: reduces the input rows to the
half. This may lead to wrong estimates for the number of rows produced by Filter operators.
