yes, o.a.m.df.mapred.* uses the old APIs and o.a.m.df.mapreduce.* uses the new ones. In fact all my latest work have been done in o.a.m.df.mapreduce.* I just kept o.a.m.df.mapred.* for compatibility with the old APIs and in case we decide to not use the APIs (I remember we had quite a trouble with the new APIs).
you can safely remove o.a.m.df.mapred.* and its related tests On Mon, Jun 14, 2010 at 6:43 PM, Sean Owen <[email protected]> wrote: > I'm about to make one of those big patches again.
