Edward J. Yoon updated HADOOP-3101:
-----------------------------------

    Attachment: 3101_v03.patch

Thanks for your review, owen.
I changed the JobClient help to FsShell help style.

{code}
[EMAIL PROTECTED] hadoop]# bin/hadoop job
Usage: JobClient <command> <args>
        [-submit <job-file>]
        [-status <job-id>]
        [-kill <job-id>]
        [-events <job-id> <from-event-#> <#-of-events>]
        [-history <jobOutputDir>]
        [-list [all]]
        [-kill-task <task-id>]
        [-fail-task <task-id>]

Generic options supported are
-conf <configuration file>     specify an application configuration file
-D <property=value>            use value for given property
-fs <local|namenode:port>      specify a namenod
-jt <local|jobtracker:port>    specify a job tracker

The general command line syntax is
bin/hadoop command [genericOptions] [commandOptions]

[EMAIL PROTECTED] hadoop]# bin/hadoop job -submit
Usage: JobClient [-submit <job-file>]
{code}

> 'bin/hadoop job' should display the help and silently exit
