> Namenode logs the UnresolvedPathExceptioneven though that file exists in HDFS.
> Each time a symlink is accessed the NN will
> throw an UnresolvedPathException to have the client resolve it.  This shouldn't
> be logged in the NN log and we could have really large NN logs  if we
> don't fix this since every MR job on the cluster will access this symlink and
> cause a stacktrace to be logged.
