Sound goods, just a little impedance between what seem to be 2 conflicting goals:
* what features we target for each release * train releases If we want to do train releases at fixed times, then if a feature is not ready, it catches the next train, no delays of the train because of a feature. If a bug is delaying the train and a feature becomes ready in the mean time and it does not stabilize the release, it can jump on board, if it breaks something, it goes out of the window until the next train. Also we have do decide what we do with 2.2.1. I would say start wrapping up the current 2.2 branch and make it the first train. thx On Wed, Nov 13, 2013 at 12:55 PM, Arun C Murthy <a...@hortonworks.com> wrote: > > On Nov 13, 2013, at 12:38 PM, Sandy Ryza <sandy.r...@cloudera.com> wrote: > > > Here are few patches that I put into 2.2.1 and are minimally invasive, > but > > I don't think are blockers: > > > > YARN-305.
