`spark.comet.memoryOverhead` configures the memory pool size for native
execution. it is not the same as `spark.executor.memoryOverhead` or
`spark.memory.offHeap.size`.
For YARN memory management, the YARN container respects the
`spark.executor.memoryOverhead` and the Comet override this value in
`CometDriverPlugin`
```
sc.conf.set(EXECUTOR_MEMORY_OVERHEAD.key, s"${execMemOverhead +
cometMemOverhead}M")
```
