Subject Re: Looking to a Hadoop 3 release

Totally agreed. I just left a comment there on the current state and what is needed. As of
now, I think the big (and only?) changes are flipping the default classloader for tasks and
splitting the HDFS jar.

Thanks,
+Vinod

I want to understand a lot more about the classpath isolation (HADOOP-11656) proposal, specifically,
what is proposed and does it have to be tagged as incompatible? That's a bigger change than
must setting javac.version=8 in the POM —though given what a fundamental problem it addresses,
I'm in favour of doing something there.

I view branch-3 as essentially the same size as our recent 2.x releases,
with the exception of incompatible changes like classpath isolation and
JDK8 target version. These, while perhaps not revolutionary, are still
incompatible, and require a major version bump.
