-----------------------------------

             Summary: DFSClient.getSnapshotDiffReport should use string path rather than o.a.h.fs.Path
                 Key: HDFS-4902
                 URL: https://issues.apache.org/jira/browse/HDFS-4902
             Project: Hadoop HDFS
          Issue Type: Bug
    Affects Versions: 2.1.0-beta
            Reporter: Binglin Chang


{code}

org.apache.hadoop.ipc.RemoteException(java.lang.AssertionError): Absolute path required

{code}

DistributedFileSystem.getSnapshotDiffReport use Path with scheme, so toString will return
path with scheme, e.g. hdfs://xxxx:8020/abc/
But FSNamesystem only accept simple path, not whole URI.
