----------------------------
Attachment: YARN-4396.005.patch
Thanks [~templedf] for the comments. Your comments look good to me. Make two
changes in the latets patch:
* Change log level from {{debug}} to {{trace}}.
* Do not print the log when the locality doesn't change.
Thanks for reviewing!

> When I configure the yarn.scheduler.fair.locality.threshold.node and
> yarn.scheduler.fair.locality.threshold.rack to open this function, I have no
> detail info of assigning container's locality. And it's important because it
> will lead some delay scheduling and will have an influence on my cluster. If
> I know these info, I can adjust param in cluster.
