Subject [jira] [Commented] (MAPREDUCE-3507) Remove Cluster as a public API on the client side.

Robert Joseph Evans commented on MAPREDUCE-3507:
------------------------------------------------

When you say remove it I assume you mean to mark it a @Private, and not really delete it.

If you are going to delete it then we really have to deprecate it first (as it is part of
an official release now 0.23.0 and 0.22 is likely to be released with it too).  If you are
just going to mark it @Private then it would be good to deprecate it too, but I am not really
sure how to do that, and not get lots of warning messages.

The public API of cluster is very confusing and doesnt add any value to the client side. This
has caused more confusion with the current jobclient/job/cluster interaction currently in
the code base. It would be best to make this private before folks actually start using it
and we will end up supporting this broken API for a long time.
