I have a problem which can be solvable using map-reduce technique. But, in my map step, I need to consider some extra information which depends on the input key,value pair. Can some one please help me what is the good way of taking this data? I am thinking of storing it in some HDFS and map code try to load it whenever it is processing a particular key, value pair. any other better approaches, please let me know. Thanks & Regards Pallavi
