> In the hot swap feature, {{FsDatasetImpl#addVolume}} uses the base volume dir 
> (e.g. "{{/foo/data0}}", instead of volume's current dir 
> "{{/foo/data/current}}" to construct {{FsVolumeImpl}}. As a result, DataNode 
> can not remove this newly added volume, because its 
> {{FsVolumeImpl#getBasePath}} returns "{{/foo}}".
