> The current computations done for tez ends up with a large AM size.
> For LLAP, we'd like stack-advisor to change these computations.
> - Total Cluster Memory <=4GB - Tez AM size = 256MB and then normalized based on YARN
minimum container size.
> - Total Cluster Memory >4GB && <= 72GB - Tez AM size = 512MB and then normalized
based on YARN minimum container size.
> - Total Cluster Memory >72GB - Tez AM size = 1536MB and then normalized based on YARN
minimum container size.
