Jason Lowe commented on YARN-2561:

bq. Yes. Update with adding with newNode instead of old rmNode.

Ah, I see now.  Before I thought the node update event was just going to the 
scheduler but now I see it's sending an event to itself which will eventually 
set totalCapability properly.

+1 on the latest patch pending Jenkins.
