------------------------------------
Summary: Proxysubmission from the Oozie client doesn't allow the
mapreduce API
Key: OOZIE-1387
URL: https://issues.apache.org/jira/browse/OOZIE-1387
Project: Oozie
Issue Type: Bug
Components: client
Affects Versions: 3.3.2
Reporter: Robert Kanter
Assignee: Robert Kanter
Fix For: trunk
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).
