> Currently DFS#isInSafeMode is not Checking for the NN state. It can be
> executed on any of the NNs.
> But HBase will use this API to check for the NN safemode before starting up
> its service.
> If first NN configured is in standby then DFS#isInSafeMode will check standby
> NNs safemode but hbase want state of Active NN.
