Inigo Goiri commented on YARN-5215:
-----------------------------------
[~curino], in our cluster we actually surface to the Web UI the utilization. We
also report negative values for the available resources. However, I think we
should do a better job exposing this information similarly to what [~jlowe] has
done in YARN-5202.
I'll start a thread in YARN-1011 about how to expose all this.

> Currently YARN runs containers in the servers assuming that they own all the
> resources. The proposal is to use the utilization information in the node and
> the containers to estimate how much is consumed by external processes and
> schedule based on this estimation.
