Carlo Curino commented on YARN-656:
-----------------------------------
I haven't seen this problem happening with the CapacityScheduler (but I was not
looking for it, so I might just have missed it).
In the CapacityScheduler reservation count against your capacity, but you might
be right that they are not counted in the metrics.
> In scheduler UI, "Memory Total" should not include reserved memory.

> "Memory Total" is currently a sum of availableMB, allocatedMB, and
> reservedMB. Including reservedMB in this sum can make the total exceed the
> capacity of the cluster.
