Karthik Kambatla commented on YARN-4485:
----------------------------------------
One potential approach is to add requestTime to ResourceRequest and use it to
compute the difference at allocation time to get per-container allocation
latency. This could be optionally rolled up at application and queue level.
> Capture per-application and per-queue container allocation latency
