[jira] [Commented] (YARN-1011) [Umbrella] RM should dynamically schedule containers based on utilization of currently allocated containers

----------------------------------------

I have been thinking of this for a while now, and would like to drive this forward. [~elgoiri] has also expressed interest in collaborating on this. Let me work on a design doc with more details and upload here. Also, it might be prudent to work on a branch.

> Currently RM allocates containers and assumes resources allocated are utilized.
> RM can, and should, get to a point where it measures utilization of allocated containers and, if appropriate, allocate more (speculative?) containers.
