Colin Ma commented on HIVE-17931:
---------------------------------
[~Ferd], I think list type reader is different with primitive type reader on
the data process. The critical method readBatch() shows the difference.
I agree some code is duplicated, eg, readPage(), and the better way to remove
these duplicated code is refactor which can be a separated ticket.
