Parameterized InputFormats

Hello,

Are there any plans to change the JobConf API so that it takes an  
instance of an InputFormat rather than the InputFormat class? I am  
finding the inability to properly parameterize my InputFormats to be  
very restricting. What's the reasoning behind having the class as a  
parameter rather than an instance?

If your InputFormat implements Configurable you'll get access to the
JobConf via the setConf(Configuration) method when Hadoop creates an
instance of your class.
