Subject [jira] [Updated] (MAPREDUCE-3004) sort example fails in shuffle/reduce stage as it assumes a local job by default
Date Fri, 16 Sep 2011 23:45:09 GMT

     [ https://issues.apache.org/jira/browse/MAPREDUCE-3004?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Arun C Murthy updated MAPREDUCE-3004:
-------------------------------------

    Status: Open  (was: Patch Available)

Looks good.

Minor nits:
# Pass is default value to 'classic' rather than do the null check
# Define 'classic' as a constant in MRConfig.
