[jira] Updated: (MAPREDUCE-372) Change org.apache.hadoop.mapred.lib.ChainMapper/Reducer to use new api.

     [ https://issues.apache.org/jira/browse/MAPREDUCE-372?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Jothi Padmanabhan updated MAPREDUCE-372:
----------------------------------------

    Attachment: mapred-372.patch

With more than a generous bout of help from Amareshwari and Devaraj, attaching a patch that modifies the original one to not rely on the getters for the context attributes.  The approach here is to have a sort of pseudo copy constructor that creates a context object based on attributes from the passed in context object. 

If we do not want to proceed with this copy-constructor approach, we might just have to postpone this patch until MAPREDUCE-954 is done. Thoughts?
