Good evening, I have a certain value output from a mapper and I want to concatenate the string outputs using a Reducer (one reducer).But the order of the concatenated string values is not in order. How can I use a reducer that receives a value from a mapper output and concatenate the strings in order. waiting your response and thanks in advance.
