Tom White updated MAPREDUCE-1623:
---------------------------------

    Attachment: MAPREDUCE-1623.patch

New patch which
* Leaves o.a.h.mapreduce.jobhistory as Private Unstable.
* Makes o.a.h.util Private.
* Makes mapreduce.filecache Private and moves the DistributedCache class 
javadoc back to o.a.h.filecache.DistributedCache. In doing this I noticed that 
the methods for o.a.h.filecache.DistributedCache have no javadoc, since they 
are inherited from o.a.h.mapreduce.filecache.DistributedCache which is now 
Private. I suggest sorting out the DistributedCache migration path in another 
JIRA, since this one is pretty unwieldly already.
* Makes the mapreduce.lib packages Evolving.

> There are lots of implementation classes in org.apache.hadoop.mapred which 
> makes it difficult to see the user-level MapReduce API classes in the 
> Javadoc. (See 
> http://hadoop.apache.org/common/docs/r0.20.2/api/org/apache/hadoop/mapred/package-summary.html
>  for example.) By marking these implementation classes with the 
> InterfaceAudience.Private annotation we can exclude them from user Javadoc 
> (using HADOOP-6658).
> Later work will move the implementation classes into o.a.h.mapreduce.server 
> and related packages (see MAPREDUCE-561), but applying the annotations is a 
> good first step.
