> Project: Oozie
> Issue Type: Bug

> Affects Versions: 3.3.2
> Reporter: Robert Kanter

> The OozieClient looks for {{mapred.mapper.class}} and
> {{mapred.reducer.class}} so they have to be specified. If a user wants to use
> a mapper/reducer that inherits from mapreduce.Mapper/Reducer (i.e. mapreduce
> API), Oozie will force them to use mapred.mapper/reducer.class to specify
> their mapper/reducer, which will make Hadoop throw an exception during the
> job.
> We should update the checking to allow either {{mapred.mapper/reducer.class}}
> or {{mapreduce.mapper/reducer.class}} as long as one or the other is
> specified.
> This isn't a problem for a regular MR action or the REST API because its
> purely an Oozie client check (OozieCLI#mrCommand).
