[infinispan-dev] MapReduceTask serialization

[Vladimir Blagojevic]

Hey,

I've sort of hit a snag with the current MapReduce design and 
serialization. Our MapReduceTask API allows users to specify Mapper, 
Reducer and Collator interfaces as anonymous classes [1]. However, we 
can not serialize instances of these classes as they are anonymous 
[2](see Note in section 1.10).

Of course, users can specify static implementations of these interfaces 
and we can put a big warning notice about anonymous class 
implementations of Mapper, Reducer and Collator but our MapReduceTask 
fluent API itself nudges users to use anonymous classes :-(

Not sure what to do! Ideas?
