Git Pull Request:
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: Dan Berindei
Fix For: 6.0.0.CR1
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).
