Re: Looking to a Hadoop 3 release

Andrew, Hadoop 3 seems in general like a good idea to me. 1. I did not understand if you propose to release 3.0 instead of 2.7 or in addition? I think 2.7 is needed at least as a stabilization step for the 2.x line. 2. If Hadoop 3 and 2.x are meant to exist together, we run a risk to manifest

Vinod, I agree that triviality is hard to define and we should not add things that can be interpreted multiple ways to the bylaws.

I'm +1 for a migrate to Java 8 as soon as possible. That's branch-2 & trunk, as having them on the same language level makes cherrypicking stuff off trunk possible. That's particularly the case for Java 8 as it is the first major change to the language since Java 5. w.r.t shipping trunk as 3.x,

Agreed. The difference between a 3.0 GA release and a parallel 2.x release line is just JDK8 + a different classpath (potentially isolated) - doesn't sound like a big enough delta warranting the license to break compat. Thanks, +Vinod On Mar 2, 2015, at 6:30 PM, Arun Murthy wrote: > Andrew, >

Andrew Thanks for bringing up the issue of moving to Java8. Java8 is important However, I am not seeing a strong motivation for changing the major number. We can go to Java8 in the 2.series. The classpath issue for Hadoop-11656 is too minor to force a major number change (no pun intended). L
