             Summary: Optimize the unified  memory manager code
                 Key: SPARK-21090
                 URL: https://issues.apache.org/jira/browse/SPARK-21090
             Project: Spark
          Issue Type: Improvement
          Components: Spark Core
    Affects Versions: 2.3.0
            Reporter: liuxian


1.In *acquireStorageMemory*, when the MemoryMode is OFF_HEAP ,the `maxMemory` should be modified to  `maxOffHeapStorageMemory`
2. Borrow memory from execution, `numBytes` modified to `numBytes - storagePool.memoryFree` will be more reasonable
