MapReduce alternatives

Are there any alternative paradigms to MapReduce (Google, Hadoop)? Is there any other reasonable way how to split & merge big problems?

Definitively. Check out, for example, Bulk Synchronous Parallel. Map/Reduce is in fact a very restricted way of reducing problems, however that restriction makes it manageable in a framework like Hadoop. The question is if it is less trouble to press your problem into a Map/Reduce setting, or if its easier to create a domain-specific parallelization scheme and having to take care of all the implementation details yourself. Pig, in fact, is only an abstraction layer on top of Hadoop which automates many standard problem transformations from not-Map-Reduce-y to Map-Reduce-compatible.
