Thanks for the explanation, Thejas. I was just wondering how come we're suddenly making a decision out of nowhere. It might be rare, but I do know users being still on 0.20. Regardless, I think a long term plan for things like this would be helpful to avoid surprises. I know we discussed about this in the past, but it never reached a consensus. Maybe we should have had a vote like this at that time.
Having said that, I understand value of the dev savings. So, go ahead. On the side note, the next thing to drop might be JDK6. Maybe we can start voting on a plan on that in advance. --Xuefu On Tue, Oct 7, 2014 at 7:48 PM, Thejas Nair <the...@hortonworks.com> wrote: > Xuefu, > > I am working on a patch that requires adding shims (HIVE-8384).
