Review request for Ambari, Alejandro Fernandez and Sumit Mohanty.
Changes
-------
Updated Test cases.
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.
Fix for safeguaring 'llap' Queue creation to max. size of 100%, in case the
minimum size required caluclated size is more than 100%.
