This sets the Memory Overhead Factor that will allocate memory to non-JVM memory, which includes off-heap memory allocations, non-JVM tasks, various systems processes, and <code>tmpfs</code>-based local directories when <code>spark.kubernetes.local.dirs.tmpfs</code> is <code>true</code>. For JVM-based jobs this value will default to 0.10 and 0.40 for non-JVM jobs.
This is done as non-JVM tasks need more non-JVM heap space and such tasks commonly fail with "Memory Overhead Exceeded" errors. This preempts this error with a higher default.
This will be overridden by the value set by <code>spark.driver.memoryOverheadFactor</code> and <code>spark.executor.memoryOverheadFactor</code> explicitly.
