Arun Suresh commented on YARN-7617:
-----------------------------------
By the way - we should also mention in the doc that the AM will only 'attempt'
to promote the container (promotion is subject to availability of actual
resources on the node)
> Add a flag in distributed shell to automatically PROMOTE opportunistic
> containers to guaranteed once they are started

> demonstrating how container promotion works.
