> 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}}".
