> Determining why the NN is not coming out of safemode is difficult - is it a bug or pending
block reports?  If the number of nodes appears sufficient, but there are missing blocks, it
would be nice to know which nodes haven't block reported (stale).  Instead of forcing the
NN to leave safemode prematurely, the SE can first force block reports from stale nodes.
> The datanode report and the web ui's node list should contain this information.
