Allow KOut/VOut emitting Mapper where VOut is null -------------------------------------------------- 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: Mircea Markus Fix For: 5.2.0.CR1, 5.2.0.Final In some cases Mapper being executed on remote nodes might produce intermediate KOut/VOut pairs where VOut is null. Should allow/account for that possibility? Currently such tasks fail with NPE.
