MapReduceHi I was just going thro abt MapReduce for my final year project work..... I got confused in the middle.... What i thought is "MapReduce deals greatly with key/value pairs only... For fitting a problem into mapreduce we should find the key/value pairs" I want to know whether im right or wrong.... I got confused after looking at the explanation in wikipedia... The following is the content in wikipedia abt mapreduce... "Continuing the previous example, what if one wanted to know the average of the test scores? One could define a reduce function which halved the size of the list by adding an entry in the list to its neighbor, recursively continuing until there is only one (large) entry, and dividing the total sum by the original number of elements to get the average." Here in map function we are simply adding up the test scores.... we are not using any key/value pair..... Im totally confused.... I might be wrong at any point... please someone help me out..... Am i wrong in the basic understanding of MapReduce itself..... Ill be thankful if anyone explains me clearly... please help me out to successfully complete my final year project....
