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
