-----------------------------------
Summary: Set the Xms value when Tez computes the heap size for a
container
Key: TEZ-3282
URL: https://issues.apache.org/jira/browse/TEZ-3282
Project: Apache Tez
Issue Type: Improvement
Reporter: Siddharth Seth
Currently, we only set the Xmx value.
Another useful change would be to change the calculation to not use the
fraction blindly. For large containers - .e.g 10GB - this ends up leaving 2G of
the container unused.
Instead we can add another parameter which indicates the max amount of memory
to leave outside the heap. Maybe a separate jira for this.
