Lei (Eddy) Xu updated HDFS-7610:
--------------------------------
Attachment: HDFS-7610.000.patch
This patch changes:
1. Use {{StorageDirectory.getCurrentDir}} to construct {{FsVolumeImpl}} when
adding the volume dynamically.
2. Changed removeVolume() to compare volumes using {{File#getCanonicalFile()}}.
3. Added a test case to verify that a newly added volume can be located and
removed.
> Should use StorageDirectory.getCurrentDIr() to construct FsVolumeImpl

>
> 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}}".
