Wangda Tan commented on YARN-8423:
----------------------------------
Thanks [~sunilg],
Overall looks good, except:
{code:java}
266 if (container.isContainerInFinalStates()) {
267 releasingGpus++;
268 }{code}
Instead of ++, you should add the actual # of allocated GPUs of the container.
And even if the patch looks safe, could u add a test to make sure there's no
regression in the future?
> GPU does not get released even though the application gets killed.
