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.
