erlang - Mapreduce with Riak -

-

Does anyone have example code for cartridge for Riak which can be run on a riege node. 

  cd ~ / riak erl -name zed@127.0.0.1 -setup riak -pa apps / Riak / ebin

In Open: 

  Connect to Server & gt; {OK, Client} = Repeat: Client_connect ('RIK @ 127.0.0.1'). {OK, {riak_client, 'riak @ 127.0.0.1', & lt; 6,201,208,64 & gt; & Gt;}} Create and insert merchandise & gt; Customer: put (riak_object: new (<< groceries} >>  
  •  << <, < ]), 1). OK & gt; Client: put (riak_object: new (>   
  •  "yours"> gt; & gt; [["egg", "sausage" ]), 1). OK # Make maps and reduce the functions & gt; Calculation = Fun (live, 'undefined', 'none') - & gt; [DC: from_list ([[I, 1]) I & lt; - riak_object: get_value (g)])] end # Fun & LT; Erl_eval.18.105910772 & gt; & Gt; Merge = Fun (Gcounts, 'none') - & gt; [Lists: GUN (funny (G, ACC) -> Dict: Merge (funny (_, x, y) -> x + y and, g, acc) end, dictionary: new (), jicount)] end . # Fun & LT; Erl_eval.12.113037538 & gt; # Reduce the map & gt; {OK, [R]} = Client: Mapad ([[& lt; <"Grocery stuff">  << <,  dict: to_list (r). [{"Eggs", 2}, {"shasija", 1}, {"bacon", 1}]
    • < P> I have used default config for the server: 

      $ hg clone http://hg.basho.com/riak/ $ cd riak $ ./rebar compile $ Cd rel $ ./riak/bin/riak start

Object type can not be changed to type. (Not properly translated,) What is a clue from the convert format, why not? And the error indicates that it is trying to convert to a string, not from.
