      Description

      Today we allocate resource (memory and cpu) and node manager starts the container with requested resource [I am assuming they are using cgroups]. But there is definitely a possibility of users requesting more than what they actually may need during the execution of their container/job-task. If we add a way for users/AM to know the actual usage of the requested/completed container then they may optimize it for next run..

      This will be helpful for AM to optimize cpu/memory resource requests by querying NM/RM to know avg/max cpu/memory usage of the container or may be containers belonging to application.
