Subject Global information in mapreduce
Date Mon, 19 Mar 2007 09:40:51 GMT
Hello! My question is about mapreduce. Is it possible to pass to the map
function some global information? For example I have a set of words and
a large set of documents. I want the map function to get each document
as value and emit pairs (word-frequency) for each word in the set, where
"frequency" is frequency of this word in the document. To do this I need
map function to have access to the set of words each time it runs. Is it
possible to do that?
