[jira] Commented: (HADOOP-3743) -libjars, -files and -archives options do not work with 0.18

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

    [ https://issues.apache.org/jira/browse/HADOOP-3743?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12643091#action_12643091 ] 

Robert commented on HADOOP-3743:
--------------------------------

I use Hadoop inside a larger system, and create JobConf instances programmatically, not via command line tools. With 0.18 I now have to set a magic flag, simply to silence the unrelated warning:

bq.  job.setBoolean("mapred.used.genericoptionsparser", true);

Wouldn't it be better to add this as a part of the JobConf API, so that it can be set or cleared as needed? This way client code wouldn't have to resort to sprinkling magic strings around.

> I am not sure how to get -libjars and -files working with 0.18. I tried all the options but cannot get it runnning. I am filing this as a blocker until we find out that its not broken. -- in that case we need to update the docs with an example to say how it works.
