[jira] [Updated] (MAPREDUCE-279) Map-Reduce 2.0

     [ https://issues.apache.org/jira/browse/MAPREDUCE-279?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Mahadev konar updated MAPREDUCE-279:
------------------------------------

    Attachment: post-move.patch
                MR-279_MR_files_to_move.txt
                MR-279-script.sh

Thanks to Vinod, attached is a script (MR-279-script.sh) and an input file (MR-279_MR_files_to_move.txt).

The script needs to be changed to point to MR-279 branch you have checked out and the trunk. The script will move map reduce runtime files around in trunk and copy the new framework from MR-279 branch to trunk. 

After running the script you will have to apply the patch (post-move.patch) on trunk. These  small changes are needed to the new framework to work with trunk.

You will have to run mvn install -DskipTests before you run any ant targets.

Also, in the script its just local mv/cp. When we actually merge the changes, it will be svn mv/copy.
