Todd Lipcon commented on MAPREDUCE-2422:
----------------------------------------
It looks like most of these deprecated methods that are being removed were only
deprecated in 0.21. As I understand it, the community has decided that we can't
remove these until after the next *stable* release (i.e 0.21 didn't count as a
release as far as API removal goes). Do you think that, instead of removing
these methods, we could keep them around as simple forwarding stubs?

> DistributedCache has a number of deprecated methods that are no longer used
> ever since TrackerDistributedCacheManager was introduced in MAPREDUCE-476.
> Removing these methods (which are not user-facing) will make it possible to
> complete MAPREDUCE-1638 by keeping DistributedCache in the API tree, and
> TrackerDistributedCacheManager, TaskDistributedCacheManager in the
> implementation tree.
