Subject: Reducer to concatenate string values


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.
