So! I think that I have to be more explicit
I have run a test mapred query using two simple map functions, each one
returns the input object (in a list). but by runnin the query I get a
badmatch error
Map1 = fun(O,_,_) -> [O] end.
Map2 = fun(O, _,_) -> [O] end.
C:mapred_bucket(<<"b7bc1418-198d-44a3-8835-8aa9cb416d5b">>, [{map, {qfun,
Map1}, none, false}, {map, {qfun, Map2}, none, true}]).
{{badmatch,{r_object,<<"b7bc1418-198d-44a3-8835-8aa9cb416d5b">>,
<<255,230,193,167,254,7,246,64,154,190,36,236,32,232,189,
