I just ran a simple program, and got the error below:

The code is CreatePartition.java:

import java.io.IOException;
import org.apache.hadoop.fs.Path;
import org.apache.hadoop.io.IntWritable;
import org.apache.hadoop.fs.FileSystem;
import org.apache.hadoop.conf.Configuration;
import org.apache.hadoop.io.SequenceFile.Writer;
import org.apache.hadoop.io.SequenceFile;

public class CreatePartition
 public static void main(String args[]) throws IOException
   Configuration conf = new Configuration();
   FileSystem fs = FileSystem.get(conf);
   SequenceFile.Writer wr = SequenceFile.createWriter(fs, conf, new Path("_sortPartitioning"), IntWritable.class, IntWritable.class);
   IntWritable k = new IntWritable(123);
   IntWritable v = new IntWritable(123);
   wr.append(k, v);
