>          Components: Spark Core
>    Affects Versions: 4.0.0
>            Reporter: Chao Sun

> Today, almost all executor memory related settings, including {{UnifiedMemoryManager}}, {{ResourceProfileManager}}, etc, are initialized before a custom Driver plugin is initialized. This means it is impossible to overwrite memory related configurations for Spark executors.
> This JIRA proposes to change the initialization for the above.
