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

             Summary: RLEv2 doesn't seem to work
                 Key: HIVE-12537
                 URL: https://issues.apache.org/jira/browse/HIVE-12537
             Project: Hive
          Issue Type: Bug
          Components: File Formats
    Affects Versions: 1.2.1

Putting 1 million constant int32 values produces an ORC file of 1MB.
Perhaps I'm doing something wrong or is actually working as expect.
Will attach code.
