    Description

      [root@trunk ~]# hdfs namenode -help
      Usage: java NameNode [-backup] | 
      	[-checkpoint] | 
      	[-format [-clusterid cid ] [-force] [-nonInteractive] ] | 
      	[-upgrade [-clusterid cid] [-renameReserved<k-v pairs>] ] | 
      	[-upgradeOnly [-clusterid cid] [-renameReserved<k-v pairs>] ] | 
      	[-rollback] | 
      	[-rollingUpgrade <downgrade|rollback> ] | 
      	[-finalize] | 
      	[-importCheckpoint] | 
      	[-initializeSharedEdits] | 
      	[-bootstrapStandby] | 
      	[-recover [ -force] ] | 
      	[-metadataVersion ]  ]
      

      There're some issues in the usage to be fixed.

      1. "Usage: java NameNode" should be "Usage: hdfs namenode"
      2. -rollingUpgrade started option should be added
      3. The last ']' should be removed.
