Jason Lowe commented on YARN-5215:
----------------------------------
Besides YARN-1011 this is also very similar to the dynamic overcommit prototype
we're running, see YARN-5202. It simply has the RM dynamically size the nodes
based on the node's reported utilization. Nodes will protect themselves from
too much overcommit by preempting containers when utilization gets too high.

> 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 actually available in the NMs.
