wang-zhun commented on issue #28069: [SPARK-31265][YARN] Add -XX:MaxDirectMemorySize jvm options in yarn mode URL: https://github.com/apache/spark/pull/28069#issuecomment-607045826 @dongjoon-hyun thanks for the reply. I think the `amMemoryOverhead` represents the usable off-heap memory. `amMemory` only means on-heap memory. Add `MaxDirectMemorySize` to better limit the off-heap memory. Of course, our Netty library also occupies this part.
