------------------------------------
Summary: Make Yarn memory overhead factor configurable
Key: SPARK-38194
URL: https://issues.apache.org/jira/browse/SPARK-38194
Project: Spark
Issue Type: Improvement
Components: YARN
Affects Versions: 3.2.1
Reporter: Adam Binford
Currently if the memory overhead is not provided for a Yarn job, it defaults to
10% of the respective driver/executor memory. This 10% is hard-coded and the
only way to increase memory overhead is to set the exact memory overhead. We
have seen more than 10% memory being used, and it would be helpful to be able
to set the default overhead factor so that the overhead doesn't need to be
pre-calculated for any driver/executor memory size.
