> During Namenode startup, we see the following message:
> {code}
> The number of live datanodes XXX has reached the minimum number 0. Safe mode will be turned off automatically once the thresholds have been reached.
> {code}
> We have not setup the datanode threshold. So this message is not necessary.
> It may be good to turn off this message if datanode threshold is not setup.
