Inigo Goiri commented on YARN-5215:
-----------------------------------
[~kasha], for the node utilization, in Windows it's pretty fast and I haven't
found any issues.
My guess is that in Linux it should be pretty fast too as it's checking single
values in /proc and not going through the whole tree.
Regarding disk and network, the node monitoring is already in trunk for both
Windows and Linux.
The utilization it's not sent to the RM but I have that pending in YARN-2965. I
can push for that this week.

> 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.
