Override the "configure" method in your Mapper class to get a handle
to the proper configuration object. Do not instantiate a new
Configuration object, as you're doing below:
Wrong:
JobConf conf = new JobConf(new Configuration());
Right:
@Override
void configure(Configuration conf) {
this.conf = conf;
}
…
…
JobConf conf = new JobConf(conf);
