Inigo Goiri commented on YARN-1011:
-----------------------------------
The second scheduling loop makes sense. I'd like the design doc to be updated
with this new approach and a couple examples on how containers would be started.
I think the next step would be to start YARN-4511 and maybe create a new JIRA
for the overallocation scheduling in the NM.
After that, we could try to implement the scheduling approach in YARN-1013 or
YARN-1015.
We would still miss the interface to mark containers/application as supporting
opportunistic; is this being tracked in any other JIRA?

> Currently RM allocates containers and assumes resources allocated are
> utilized.
> RM can, and should, get to a point where it measures utilization of allocated
> containers and, if appropriate, allocate more (speculative?) containers.
