    Description

      https://github.com/apache/hive/blob/9b36ffa92cc4e0f47ea03d8d167debe743342f5b/ql/src/java/org/apache/hadoop/hive/ql/exec/Utilities.java

      Please change the signature of these methods to be Set or Collection

      public static List<String> getColumnNames*

      Often these calls are being used to get a list of columns, then searched through. It would be more performant (and database set-theory correct) if the returned data type was a Set and not a List. And they should probably be immutable collections returned as well.
