> DBException 1 and 2 is due to Sorted table file 000005.sst being deleted
> accidentally.
> DBException 3 is due to MANIFEST being deleted accidentally.
> It would be better to handle these errors instead of NM failed to start with
> DBException.
> For these DBExceptions, if we delete the LevelDB text file CURRENT, NM will
> recover successfully from the DBException.
> CURRENT is a simple text file that contains the name of the latest MANIFEST
> file.
