Hello,
I'm trying to write a simple MR job using _javascript_ and hit a wall right at start. I can't figure out how to specify "inputs". Here's the code: curl -XPOST "my_riak_server:8098/mapred" -H "Content-Type: application/json" -d @- <<EOF { "input": "my_bucket" "query":[{ "map":{ "language":"_javascript_", "source":"function(riakObject, keydata, arg) { var m = riakObject.values[0].data; return [m]; }" } }] } EOF this returns empty array. Aside: I know that listing all keys is slow but for now I can live with this. Note, that I'm using non-default bucket type, so the actual location of my keys is my_riak_server/types/my_bucket_type/buckets/my_bucket/my_key, but I can't figure out how to communicate this location properly in the "input" field. I have found this "documentation": https://github.com/basho/riak_kv/blob/2.1/src/riak_kv_mapred_json.erl#L101, but it does not explain how to specify bucket type and I'm not proficient enough in Erlang to follow the code easily. I did not find any other documentation on this field. Following returns all keys successfully, so data is there: Any pointers are highly appreciated. Thanks, Timur | ||
