- = Hadoop Generic Options =
-
- 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.
