      Description

      Courtesy Andreina,

      When "dfs.namenode.safemode.min.datanodes" is configured to n
      So namenode will be in safemode until n DN are registered with the namenode .
      But in UI it displays that n+1 datanodes are additionally needed. And "safe mode will be turned off automatically " message is also displayed .
      ==========
      "dfs.namenode.safemode.min.datanodes" =2
      Started the NN
      The UI report displays that

      "Safe mode is on.The number of live datanodes 0 needs additional 3 live inimum number 2. Safe mode will turned off automatically".
