I just wrote something quick that uses groovy scripts. my hope is to
be able to execute any arbitrary scripted mapper/reducer w/o needing

Ray, to avoid duplicate effort, I'm working on implementing "stored
scripts" for Infinispan based on ScriptEngine.
Scripts would be stored (compiled if possible) in a dedicated replicated
cache. The scripts can then be referred to by name in dist-exec and
map-reduce invocations. It will then be possible to invoke these scripts
both locally and remotely (over HotRod and REST).
