Robert Kanter commented on HADOOP-11090:
----------------------------------------
The nightly JDK8 builds are definitely in a better state than they were before.
Common has been mostly green now, MR was until yesterday, and YARN has been
mostly green lately too. HDFS's build still needs some work though.
That said, I'm not sure it makes sense to wait for all of these builds to be
green before switching over. With the number of commits going into Hadoop each
day, we're basically trying to hit a moving target here. I think we might be
better of switching the pre-commit build to JDK8 so that we can catch anything
before it goes in. And I guess we should probably get YARN-3528 moving again
as well.
