Varun Vasudev commented on YARN-6504:
-------------------------------------
I had a bunch of conversations about whether we should support override
capabilities. My reason for adding it in the end is that without overrides,
every existing job has to be re-written and re-tested, etc to match the
profiles the admin creates. However, I'm in heavy favor of allowing overrides
for memory and vcores only and not letting users override other resource types.
