Inigo Goiri commented on YARN-4808:
-----------------------------------
I like the idea of reusing the utilization data from {{RMNode}}; I can move all
this into YARN-4511.
> SchedulerNode can use a few more cosmetic changes

> Key: YARN-4808

> Project: Hadoop YARN
> Issue Type: Improvement

> We have made some cosmetic changes to SchedulerNode recently. While working
> on YARN-4511, realized we could improve it a little more:
> # Remove volatile variables - don't see the need for them being volatile
> # Some methods end up doing very similar things, so consolidating them
> # Renaming totalResource to capacity. YARN-4511 plans to add inflatedCapacity
> to include the un-utilized resources, and having two totals can be a little
> confusing.
