[jira] [Created] (HIVE-13637) Fold CASE into NVL when CBO optimized the plan

Jesus Camacho Rodriguez created HIVE-13637:
----------------------------------------------

             Summary: Fold CASE into NVL when CBO optimized the plan
                 Key: HIVE-13637
                 URL: https://issues.apache.org/jira/browse/HIVE-13637
             Project: Hive
          Issue Type: Sub-task
          Components: CBO
    Affects Versions: 2.1.0
            Reporter: Jesus Camacho Rodriguez
            Assignee: Jesus Camacho Rodriguez


After HIVE-13068 goes in, folding CASE into NVL got disabled when CBO has optimized the plan, as it was done by ConstantPropagate in Hive. We need to enable it back.
