      Description

      After HADOOP-4103, "-metaSave" on NameNode prints "MISSING" in the line for a block that does not have any good replicas left.

      e.g. :

      Metasave: Blocks waiting for replication: 1
      blk_6735500019364591152_0 (replicas: l: 0 d: 0 c: 2 e: 0 MISSING) 74.6.132.200:50010 :  192.168.0.107:50010 :
      

      "0 MISSING" in the log might imply to the user that there is no missing block, though it implies "e(xcess replicas) : 0".

      We should fix that. Also as part of this I would like to indicate which datanodes are decommissioned or contain the corrupt replicas.
