-------------------------------
Hi [~sandflee]
YARN-1769 introduced {{reservations-continue-look-all-nodes}}. I think this may
help in cases like this. So one reservation wont be fully stuck on a node
forever till it gets enough space. This will help to look for a better option.
If this doesnt help, we could try to ass some good improvements to this so that
more eligible pending requests can use that space (node).
