The community made a decision long time ago that we'd like to keep the compatibility & so tie branch-2 to Java 7, but do Java 8+ only work on 3.x.
I always assumed that most (all?) downstream users build branch-2 on JDK 7 only, can anyone confirm? If so, there may be an easier way to address these test issues. +Vinod > On Jan 28, 2019, at 11:24 AM, Jonathan Hung <jyhung2...@gmail.com> wrote: > > Hi folks, > > Forking a discussion based on HADOOP-15711.
