             Summary: Replacing ArrayList params with List in and around PlanUtils and MapWork
                 Key: HIVE-21962
                 URL: https://issues.apache.org/jira/browse/HIVE-21962
             Project: Hive
          Issue Type: Improvement
            Reporter: Ivan Suller
            Assignee: Ivan Suller


Using the implementing class is usually a bad practice. OO suggest to use the least restrictive interface instead. ArrayList is used in many-many methods as a parameter - this is just a tiny part of this work.
