> Steps I did to run into this:
> 1. Start a new NN, freshly formatted.
> 2. No DNs yet.
> 3. Visit the DFS browser link {{http://localhost:50070/nn_browsedfscontent.jsp}}
> 4. Above error shows itself
> 5. {{hdfs dfs -touchz afile}}
> 6. Re-visit, still shows the same issue.
> Perhaps its cause of no added DN so far.
