             Summary: Allow non-emitting Mapper  
                 Key: ISPN-2353
                 URL: https://issues.jboss.org/browse/ISPN-2353
             Project: Infinispan
          Issue Type: Bug
          Components: Distributed Execution and Map/Reduce
    Affects Versions: 5.2.0.Alpha4
            Reporter: Vladimir Blagojevic
            Assignee: Vladimir Blagojevic
             Fix For: 5.2.0.Beta1, 5.2.0.Final

In some cases Mapper being executed on remote nodes might not produce any intermediate KOut/VOut pairs and we should allow/account for that possibility. Currently such tasks fail with NPE.
