Can a webserver be implemented using mapreduce?

Could mapreduce be used to implement a web开发者_StackOverflow中文版server?

I'm thinking something like when a request comes in then the request sits on a queue, until a server is free to process it? Or am I missing the point here?

I think you're missing the point. MapReduce is a way of breaking up a large data set so that it can be distributed among a number of compute nodes for parallel processing.
