Date Thu, 01 Apr 2010 21:16:27 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-1666?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12852551#action_12852551

Arun C Murthy commented on MAPREDUCE-1666:

By 'output' you mean on HDFS? 

> job output chroot support
> -------------------------
>                 Key: MAPREDUCE-1666
>                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-1666
>             Project: Hadoop Map/Reduce
>          Issue Type: New Feature
>          Components: job submission
>    Affects Versions: 0.20.2
>            Reporter: Allen Wittenauer
>            Priority: Minor
> It would be useful to be able to submit the same job and have it chroot the output to
a different base directory before execution.  This would allow for input to be the same, but
output different for the same job over multiple runs (potentially by different users).
