Eric Payne commented on YARN-5994:
----------------------------------
Thanks [~ebadger] for reporting and fixing this issue.
The only thing I found is that the patch does not build in branch-2 or
branch-2.8 because the anonymous inner class returned by
{{GenericTestUtils.waitFor}} in
{{TestCapacityScheduler#verifyAMLimitForLeafQueue}} uses both of the
{{nodeMemory}} and {{scheduler}} local variables. Since both branch-2 and
branch-2.8 are compiling with java 2.7, these variables need to be final.
The patch looks good to me. I give my +1. I will commit this soon if there are
no objections, and I will fix the {{final}} issues as part of the backport to
branch-2 and branch-2.8.
