Re: newbie question
Don't you need to set this

     conf.setMapperClass(Mapper.class);

to BuildGraph?

I have a mapper
    public class BuildGraph{
       public void config(JobConf job){ <==this block doesnt seems to be exexcuting at all :(
        super.configure(job);
        this.currentId = job.getInt("currentId",0);
        if (this.currentId!=0){
        // I call a method from differnt class to build a distributed cache
        }
       }
      public void map(....){
    ....
    }
}

now the main code where this is called..

    public void run( String params,curId){
     JobConf conf = new JobConf(classname.class);
     conf.setInt("currentId",299); <--note this i am setting the value here
     conf.setMapperClass(Mapper.class);
     //....
      JobClient.runJob(conf);
    }

But the problem is config method in the code is not executing as though "currentId" returns 299 in main loop but it is not set at all in the mapper class.
what am i doing wrong
