No, you are correct, I replied from memory rather than checking the API first,
sorry.

Hmmm. I believe that validation should have been removed since Riak 1.1
MapReduce can be executed without phases. I've raised an issue for that[1].
Until it is fixed you can't try the example I suggested.
Well you can. Just use the raw client and provide a JSON string to it
String jsonString = "{\"inputs\":{\"bucket\":\"mybucket\",
\"index\":\"myindex_bin\", \"key\":\"mykey\"}, \"query\": []}";
rawClient.mapReduce(new MapReduceSpec(jsonString));
If that is much faster then the reduce phases are to blame. Try adding back
one, then the other. I have a suspicion that the JS reduce is the problem.
