Subject [jira] Updated: (MAPREDUCE-711) Move Distributed Cache from Common to Map/Reduce
Date Thu, 09 Jul 2009 12:17:14 GMT

     [ https://issues.apache.org/jira/browse/MAPREDUCE-711?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Vinod K V updated MAPREDUCE-711:
--------------------------------

    Attachment: MAPREDUCE-711-20090709-mapreduce.txt
                MAPREDUCE-711-20090709-common.txt

I am taking this up; this is need for other DistributedCache related issues - HADOOP-4493
and MAPREDUCE-476.

Attached are two patches, one for common project and one for mapreduce project. The patches
are generated by simple refactoring in eclipse across projects. I've created new package org.apache.hadoop.mapred.filecache
in both src/java as well as src/test/mapred.

I have run the tests that are directly affected by these patches, and they pass. Will run
all the common and mapreduce tests in the background.

Few questions:
 - Do I need a separate jira issue for common part, given It is just moving of files across
projects? Can open a new issue if felt otherwise.
 - What happens to the repository history of these files? Is there any possible way we can
move repo history too?

> Distributed Cache logically belongs as part of map/reduce and not Common.
