[jira] Commented: (HADOOP-3101) 'bin/hadoop job' should display the help and silently exit

["Amar Kamat (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HADOOP-3101?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12586323#action_12586323 ] 

Amar Kamat commented on HADOOP-3101:
------------------------------------

Three comments
1) You can delete the {{throw IOException}} statement instead of commenting it out.
2) Because of spaces there is a diff generated (line 29 and 32 of the patch). I think we can avoid that. 
3) Plz document the change made in {{GenericOptionsParser.java}} in the javadoc. Btw {{getRemainingArgs()}} is a public api and there is a change is what it returns. Should there be a concern?
Rest looks good.

> Currently 'bin/hadoop job' displays help and throws an exception. Like other commands (e.g dfs) it should silently come out.
