      Description

      When datanode gets shutdown by calling DataNode#shutdown, it occasionally leaves the data block scanner verification log unclosed. There are two possible causes:
      1. DataNode does not wait until block scanner thread to exit.
      2. DataBlockScanner does not guarantee that the verification log is closed if the scanner is interrupted.
