> In Submitter.java,
> {noformat}
> 228 setIfUnset(conf, "mapred.output.key.class", textClassname);
> 229 setIfUnset(conf, "mapred.output.value.class", textClassname);
> 230 setIfUnset(conf, "mapred.output.key.class", textClassname);
> 231 setIfUnset(conf, "mapred.output.value.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.)
