> of LLAP normalized from <memory:186368, vCores:1> to <memory:143616, vCores:1>
> {code}
> This behavior should be made configurable. It will allow app owners to choose
> if they want normalization and the app to continue running with reduced
> resources (as default), OR if they do not want normalization and want the app
> to fail right away, rather than several days later when it actually tries to
> use as much memory it had requested, but never got. This causes a debugging
> nightmare as well, trying to figure out why the app was even killed by YARN
> when it exceeded the resource usage.
