> Components: net
> Affects Versions: 2.0.2-alpha, 3.0.0-alpha1

> 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.
