[jira] [Created] (SPARK-10984) Simplify *MemoryManager class structure

Andrew Or created SPARK-10984:
---------------------------------

             Summary: 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
