      Description

      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.
