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).
