      Description

      There is an inconsistency between the console outputs of 'hdfs dfsadmin' command and 'hdfs dfsadmin -help' command.

      [root@trunk ~]# hdfs dfsadmin
      Usage: java DFSAdmin
      Note: Administrative commands can only be run as the HDFS superuser.
                 [-report]
                 [-safemode enter | leave | get | wait]
                 [-allowSnapshot <snapshotDir>]

                 [-saveNamespace]
                 [-rollEdits]
                 [-restoreFailedStorage true|false|check]

                 [-metasave filename]

                 [-refreshUserToGroupsMappings]
                 [-refreshSuperUserGroupsConfiguration]
                 [-refreshCallQueue]
                 [-refresh]
                 [-printTopology]
                 [-refreshNamenodes datanodehost:port]

                 [-getDatanodeInfo <datanode_host:ipc_port>]
                 [-help [cmd]]
      
      [root@trunk ~]# hdfs dfsadmin -help
      hadoop dfsadmin performs DFS administrative commands.
      The full syntax is: 
      
      hadoop dfsadmin
      	[-report [-live] [-dead] [-decommissioning]]
      	[-safemode <enter | leave | get | wait>]
      	[-saveNamespace]
      	[-rollEdits]
      	[-restoreFailedStorage true|false|check]
      	[-refreshNodes]
      	[-setQuota <quota> <dirname>...<dirname>]
      	[-clrQuota <dirname>...<dirname>]
      	[-setSpaceQuota <quota> <dirname>...<dirname>]
      	[-clrSpaceQuota <dirname>...<dirname>]
      	[-finalizeUpgrade]
      	[-rollingUpgrade [<query|prepare|finalize>]]
      	[-refreshServiceAcl]
      	[-refreshUserToGroupsMappings]
      	[-refreshSuperUserGroupsConfiguration]
      	[-refreshCallQueue]
      	[-refresh <host:ipc_port> <key> [arg1..argn]
      	[-printTopology]
      	[-refreshNamenodes datanodehost:port]
      	[-deleteBlockPool datanodehost:port blockpoolId [force]]
      	[-setBalancerBandwidth <bandwidth>]
      	[-fetchImage <local directory>]
      	[-allowSnapshot <snapshotDir>]
      	[-disallowSnapshot <snapshotDir>]
      	[-shutdownDatanode <datanode_host:ipc_port> [upgrade]]
      	[-getDatanodeInfo <datanode_host:ipc_port>
      	[-help [cmd]
      

      These two outputs should be the same.
