Hi, all I've got a question about how to make different mappers execute different processing on a same data?
Here is my scenario: I got to process a data, however, there multiple choices to process this data and I have no idea which one is better, so I was thinking that maybe I could execute multiple mappers, in which different processing solution is applied, and eventually the best one is chosen according to some evaluation functions. But I'm not sure whether this could be done in MapReduce. Any help would be appreciated. -- YANG, Lin
