[Umbrella] Schedule containers based on utilization of currently allocated containers

    Details

    • Type: New Feature
    • Status: Open
    • Priority: Major
    • Resolution: Unresolved

      Description

      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.
