-Re: Porting policy from 0.94 to 0.92
Todd Lipcon 2012-09-06, 18:26
With my Apache hat on: the policies used by distribution vendors may
differ from the policies in the project itself. I think the Apache
project should be concerned with pushing the ball forward on new
releases and not on backporting features to older branches. Vendors
have internal QA teams and may have pressure from customers to
backport things that don't necessarily make sense to spend effort on
in upstream stable releases.
The fact that a Cloudera build for a specific customer has a certain
patch doesn't necessarily have bearing on whether the community at
large feels it is appropriate for that branch.
