Hemanth Yamijala commented on MAPREDUCE-711:
--------------------------------------------
To summarize:
- We moved the distributed cache out of common, as no one else is using it.
- We moved it into mapred, with the old package name and it is deprecated.
- We repackaged the classes into o.a.h.mapreduce.filecache.DistributedCache
that the deprecated classes in mapred extend.
This is blocking other JIRAs. I think the approach here is approved by Owen
(from comments above) and from Philip, with the exception of the package name.
I think committing this soon will unblock other work. So I propose going ahead
after running tests once more on the new trunk. We could change the package
name to o.a.h.mapreduce.distributedcache in a follow-up JIRA. As long as it
will be in Hadoop 0.21, we can change the package name without worrying about
compatibility.

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