Re: help: InputFormat problem ?

[Owen O'Malley]

If your application that you are drawing from is doing some sort of  
web crawl that connects to lots of random servers, you may want to use  
MultiThreadedMapRunner and do the remote connections in the map. If  
you are just connecting to a small set of servers for each map, you  
should put it in the InputFormat.

Using MultiThreadedMapRunner means that each map can have multiple  
threads transferring data from the external sources.
