Steve Loughran commented on SLIDER-938:
---------------------------------------
Two strategies
# autonomous: do it for the user
# based on manual update of resources.json
option #2 keeps the user aware of what is needed and ensures that restarted
apps have the amount of memory/CPU that they need, also lets people shrink down.
This would be YARN 2.8+ only
> Add ability to resize containers (Hadoop 2.8+)
