>     228     setIfUnset(conf, "mapred.output.key.class", textClassname);

> {noformat}
> I think this meant to set mapred.*map*output.{key,value}.class instead of setting the same conf twice.
> (It doesn't really matter since mapred.mapoutput.{key,value}.class defaults to mapred.output.{key,value}.class.)
