-----------------------------------
Summary: Add a max cap to the heap computation done by Tez
Key: TEZ-3283
URL: https://issues.apache.org/jira/browse/TEZ-3283
Project: Apache Tez
Issue Type: Improvement
Reporter: Siddharth Seth
Change the calculation to not use the fraction blindly. For large containers -
.e.g 10GB - this ends up leaving 2G of the container unused / outside of the
heap.
Instead we can add another parameter which indicates the max amount of memory
to leave outside the heap - defaulting to 1G
