Subject Re: Working Formula for Hive 0.13?
Date Mon, 25 Aug 2014 20:08:42 GMT
Thanks for working on this!  Its unclear at the moment exactly how we are
going to handle this, since the end goal is to be compatible with as many
versions of Hive as possible.  That said, I think it would be great to open
a PR in this case.  Even if we don't merge it, thats a good way to get it
on people's radar and have a discussion about the changes that are required.
