RE: Where are map and reduce functions from the Gridmix2 examples

[stanley.shi]

I was just reading the gridmix2 code, happy to find that I can answer this 
question:
For javasort, I see these two lines of code:
                                        
jobConf.setMapperClass(IdentityMapper.class);
                                        
jobConf.setReducerClass(IdentityReducer.class);
for Monsterquery, webdatascan, webdatasort:
        job.setMapperClass(SampleMapper.class);
    job.setReducerClass(SampleReducer.class);
For combiner,
        conf.setMapperClass(MapClass.class);
    conf.setCombinerClass(Reduce.class);
    conf.setReducerClass(Reduce.class);

seems that they have done nothing...
can anyone further explain that?

Thanks,
stanley

Subject: Where are map and reduce functions from the Gridmix2 examples

Hi,


1 - I'm looking for the map and reduce functions of the several
examples of the Gridmix2 platform (Webdatasort, Webdatascan,
Monsterquery, javasort and combiner) and I can't find it? Where can I
find these functions?

2 - Does anyone know what the Webdatasort, Webdatascan, Monsterquery,
javasort and combiner examples from the Gridmix2 does?


Thanks,
