I want to run LineIndexer example, but I've got some problem. I want to use
both setMapperClass method and JobClient object. I impoted the following,
but It does not work. What's the matter?
--------------------------------------
import org.apache.hadoop.mapred.*;
import org.apache.hadoop.mapred.JobConf;
import org.apache.hadoop.mapred.JobClient;
--------------------------------------
conf.setMapperClass(LineIndexer.LineIndexerMapper.class);
conf.setReducerClass(LineIndexer.LineIndexerReducer.class);
if (args.length < 2) {
System.out.println("Usage: LineIndexer <input path> <output
path>");
System.exit(0);
}
conf.setInputPath(new Path(args[0]));
conf.setOutputPath(new Path(args[1]));
JobClient.runJob(conf);
--------------------------------------
