+ Hadoop has an option parsing framework that employs parsing generic options as well as running classes. Hadoop generic arguments are :
+ 
+ {{{-conf <configuration file>}}}  : specify an application configuration file
+ 
+ {{{-D <property=value>}}}        : use value for given property
+ 
+ {{{-fs <local|namenode:port>}}}   : specify a namenode  {{{local}}} means use the local file system as your DFS, {{{<namenode:port>}}} specifies a particular name node to contact.
+ 
+ {{{-jt <local|jobtracker:port>}}} :   specify a job tracker
+ 
+ The general command line syntax is
+ 
+ {{{bin/hadoop command [genericOptions] [commandOptions]}}}
+ 
+ 
+ dfs, distcp and job targets accept these generic options.
