I am trying to use this fuctntion to get the highest number from given date.
My map is working fine but reduce function is giving me error. Please help me
curl -X POST http://x:8098/mapred -H "Content-Type: application/json" -d @-
function(value, keyData, arg){
var data = Riak.map.ValuesJson(value) [0];
return [data.High];
}
{"inputs":[["symc","2011-10-04"],
["symc","2011-09-02"],
["symc","2011-10-03"]],
"query":[{"map":{"language":"javascript",
"source":"function(value, keyData, arg) { var data =
Riak.mapValuesJson(value)[0]; return [data.High];}"
}}
{"reduce":{"language":"javascript","name":"Riak.reduceMax","keep":true}}]
}
--Ctrl-D to submit it
Output :
The POST body was not valid JSON.
The error from the parser was:
{{case_clause,<<"function(value, keyData, arg){ var data =
Riak.map.ValuesJson(value) [0]; return
[data.High];}{\"inputs\":[[\"symc\",\"2011-10-04\"],

\"query\":[{\"map\":{\"language\":\"javascript\",
\"source\":\"function(value, keyData, arg) { var data =
Riak.mapValuesJson(value)[0]; return [data.High];}\"
}}
{\"reduce\":{\"language\":\"javascript\",\"name\":\"Riak.reduceMax\",\"keep\":true}}]}">>},
