Josh Rosen commented on SPARK-10984:
------------------------------------
I'm actually planning to work on this, given that it's going to need to touch a
fair amount of internals.
> Simplify *MemoryManager class structure
> ---------------------------------------
>
> Key: SPARK-10984
> URL: https://issues.apache.org/jira/browse/SPARK-10984
> Project: Spark
> Issue Type: Sub-task
> Components: Spark Core
> Reporter: Andrew Or
>
> This is a refactoring task.
> After SPARK-10956 gets merged, we will have the following:
> - MemoryManager
> - StaticMemoryManager
> - ExecutorMemoryManager
> - TaskMemoryManager
> - ShuffleMemoryManager
> This is pretty confusing. The goal is to merge ShuffleMemoryManager and
> ExecutorMemoryManager and move them into the top-level MemoryManager abstract
> class. Then TaskMemoryManager should be renamed something else and used by
> MemoryManager, such that the new hierarchy becomes:
> - MemoryManager
> - StaticMemoryManager
