> Once in a while , we want to debug by bringing up the namenode without any datanodes.
 dfs -ls/-lsr works, but fsck / takes too much time. (at least 10 times more)  Most likely
from HADOOP-943 that I requested.  If this is the case, it would be nice if we can have an
option for disabling it for this special case.
