Tsuyoshi OZAWA commented on YARN-2977:
--------------------------------------
[~kasha], Thank you for pointing out. When we had voting for 2.6.0, HDFS-6833
was reported as a blocker of 2.6.1 release. But as you mentioned, this is a
test fix and not critical issue. Should we revert against brach-2.6 and move
the changes against CHANGELOG.txt to 2.7?

> There are still some test failures for TestNMClient in slow testbed. Like my
> comments in YARN-2148, the container could be finished before
> CLEANUP_CONTAINER happens due to slow start. Let's add back exit code 0 and
> add more message for test case.
> The failure stack:
> java.lang.AssertionError: null
