> During the start up, namenode waits for n replicas of each block to be
> reported by datanodes before exiting the safe mode. Currently n is tied to
> the min replicas config. We could set min replicas to more than one but we
> might want to exit safe mode as soon as each block has one replica reported.
> This can be worked out by introducing a new config variable for safe mode
> block count
