      Description

      Following two can be refactored,
      1 ) private final String usagePrefix =
      "Usage: hadoop fs [generic options]";

      This will come for hadoop fs,hdfs dfs...I feel, it can be separated out

      2 ) Following generics also will be called for dfs, haadmin which is not required.

      ToolRunner.printGenericCommandUsage(out);
      public static void printGenericCommandUsage(PrintStream out)

      { out.println("Generic options supported are"); out.println("-conf <configuration file> specify an application configuration file"); out.println("-D <property=value> use value for given property"); out.println("-fs <local|namenode:port> specify a namenode"); out.println("-jt <local|jobtracker:port> specify a job tracker"); out.println("-files <comma separated list of files> " + "specify comma separated files to be copied to the map reduce cluster"); out.println("-libjars <comma separated list of jars> " + "specify comma separated jar files to include in the classpath."); out.println("-archives <comma separated list of archives> " + "specify comma separated archives to be unarchived" + " on the compute machines.\n"); out.println("The general command line syntax is"); out.println("bin/hadoop command [genericOptions] [commandOptions]\n"); }
