Sahil Takiar commented on HIVE-14029:

[~Ferd] overall this looks good to me. It would be nice if you could update the 
description to list out the high-level changes that needed to be made to Hive 
to add support for Spark 2.0.0. For example, dependency updates, which APIs 
changed (change from Iterable to Iterator, InputMetrics constructor change).
