Devaraj K commented on YARN-6620:
---------------------------------

Thanks [~leftnoteasy] for the quick patch.

bq. Switched JAXB to handle XML parsing instead of check tags.
Overall looking good, it would be better if you could group the adapter and other supporting
classes as inner classes in PerGpuDeviceInformation.
