> Trying to run application on Nodelabel partition I  found that the 
> application execution time is delayed by 5 – 10 min for 500 containers . 
> Total 3 machines 2 machines were in same partition and app submitted to same.
> After enabling debug was able to find the below
> # From AM the container ask is for OFF-SWITCH
> # RM allocating all containers to NODE_LOCAL as shown in logs below.
> # So since I was having about 500 containers time taken was about – 6 minutes 
> to allocate 1st map after AM allocation.
> # Tested with about 1K maps using PI job took 17 minutes to allocate  next 
> container after AM allocation
> Once 500 container allocation on NODE_LOCAL is done the next container 
> allocation is done on OFF_SWITCH
