I call MongoTemplate.mapReduce method with these codes:

MapReduceResults<Bar> results =


But I found in log file of mongodb, the mapReduce command was run with option { out: { inline: 1} ...}


I read the source code of mapReduce function, MongoTemplate, and found that the mapReduceOptions parameter was not used to create MapReduceIterable object, and outputCollection and outputType of mapReduceOptions has never been processed.
