+ 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.
