      Description

      For a topology decision of DataNode and TaskTracker, ScriptBasedMapping (probably TableMapping) confirms HashMap first.
      To decide topology of DataNode and TaskTracker again, it is necessary to restart NameNode and JobTracker.
      Therefore, it is necessary to change (or clear) HashMap function without restarting NameNode and JobTracker.
