             Summary: The default map/reduce cache configuration should have state transfer enabled
                 Key: ISPN-3401
                 URL: https://issues.jboss.org/browse/ISPN-3401
             Project: Infinispan
          Issue Type: Bug
          Components: Distributed Execution and Map/Reduce
    Affects Versions: 6.0.0.Alpha2
            Reporter: Dan Berindei
            Assignee: Mircea Markus
             Fix For: 6.0.0.Final


Map/Reduce uses a CreateCacheCommand to create an intermediate cache for the mapper/combiner results. The default configuration for the intermediate cache has fetchInMemoryState disabled, which is probably not a good idea.

CreateCacheCommand also seems too tightly linked to M/R, it contains both the default intermediate cache configuration and a mechanism to check that the cache has started that adds random keys to the cache (and so it can't be re-purposed for creating regular caches).
