---------------------------------
Summary: The status of free pages in allocatedPages mismatch with
pageTable after invoking TaskMemoryManager::cleanUpAllAllocatedMemory
Key: SPARK-43507
URL: https://issues.apache.org/jira/browse/SPARK-43507
Project: Spark
Issue Type: Bug
Components: Spark Core
Affects Versions: 3.4.0
Reporter: qian heng
For TaskMemoryManager, `allocatePags` is a Bitmap for tracking free pages in
`pageTables`.
But inner TaskMemoryManager::cleanUpAllAllocatedMemory, it fills up
`pageTables` with null but not clear up the `allocatePags`. It leads to the
status of free pages mismatch between them.
