Review request for Ambari, Alejandro Fernandez and Sumit Mohanty.


Bugs: AMBARI-17331
    https://issues.apache.org/jira/browse/AMBARI-17331


Repository: ambari


Description
-------

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.
