Devaraj Das updated MAPREDUCE-744:
----------------------------------

    Attachment: 744-5.patch

bq. 1. DistributedCache.get*Visibiliteies - are deprecated. Why do we add 
deprecated methods?
Ok it looks like we don't have to really add the methods in DistributedCache 
since the methods are used only by the framework. So i moved the accessors 
(getFileVisibilities/getArchiveVisibilities) to TrackerDistributedCacheManager 
where the setters are defined.
This seems like the right thing to do ..
