Description:
Note: Only impacts a user if {{dfs.namenode.snapshot.trashroot.enabled}} is
enabled.
Root cause analysis:
{{SnapshottableDirectoryStatus}} paths retrived inside
{{DFSClient#getSnapshotRoot}} aren't appended with '/', causing some
directories with the same path prefix to be mistakenly classified as
snapshottable directory.
Thanks [~shashikant] for the test case addition.
