Edward Capriolo commented on HIVE-1511:
---------------------------------------
[~xuefuz]When you filed your ticket my comment was referencing this one.
This looks good. I want to start looking at the jar jar plugin, because I do
not like how the hive-exec jar is getting larger and larger and possible
classpath conflicts can happen. But that is something down the road.
I like this speed up, maybe we should try jackson as well since we already have
it on the classpath and it will still keep the plan readable.
I am assuming you do not want to go +1 because you still have println in there.
