My driver function looks like this -
public static void main(String[] args) throws IOException,
InterruptedException, ClassNotFoundException {
// TODO Auto-generated method stub
Configuration conf = new Configuration();
Job job = new Job();
conf.set("stream.recordreader.class",
"org.apache.hadoop.streaming.StreamXmlRecordReader");
conf.set("stream.recordreader.begin", "<info>");
conf.set("stream.recordreader.end", "</info>");
job.setInputFormatClass(StreamInputFormat.class);
job.setOutputKeyClass(Text.class);
job.setOutputValueClass(IntWritable.class);
FileInputFormat.addInputPath(job, new Path("/mapin/demo.xml"));
FileOutputFormat.setOutputPath(job, new Path("/mapout/demo"));
job.waitForCompletion(true);
}
Could you please out my mistake??
Regards,
Mohammad Tariq
