             Summary: LLAP Improvements to per executor memory computation in 
daemons
                 Key: HIVE-14102
                 URL: https://issues.apache.org/jira/browse/HIVE-14102
             Project: Hive
          Issue Type: Improvement
            Reporter: Siddharth Seth


Currently set to 80% of maxAvailableMemory - irrespective of container size. 
This can end up with a lot of wastage.

Also - the 80% / overhead may already be accounted for in YARN container sizing 
calculations. This should not be double counted.
