Jason Lowe updated YARN-1801:
-----------------------------
Target Version/s: 2.6.0 (was: 2.4.1)
Affects Version/s: 2.2.0
[~beckham007] what Hadoop version corresponds to the log messages above? The
logs imply it might be something close to Hadoop 2.2 since the NPE is on the
same line number as originally reported.
The core problem with the original NPE is that assoc should never be null
unless there's a code bug, and we closed a race condition that could cause that
in YARN-1575. It would be good to know if you're already running on a version
that includes the fix from YARN-1575, and if not, can you reproduce the
problem after including that fix.
