Constructing a JobConf without a class leads to a very misleading error message.

    Description

      If this line from a typical map/reduce program

      JobConf conf = new JobConf(Flatten.class);

      has the argument deleted then I get a message that the input format that I specify cannot be found. That message leads a naive user on a rat chase. I only corrected this by bisecting against a working program.
