> Paths returned from DFS internally cache their FileStatus, so that getStatus(Path) does not require another RPC. This cache is never refreshed and become stale, resulting in program error.
> This should not be fixed until FileSystem#listStatus() is removed by HADOOP-2563, and user code is thus no longer dependent on this cache for good performance.
