mapreduce to read hive table and write to hdfs location with context

Question

I am looking out for the mapreduce program to read from one hive table and write to hdfs location of first column value of each record. And it should contain only map phase not reducer phase.

Below is the mapper

public class Map extends Mapper<WritableComparable, HCatRecord, NullWritable, IntWritable> {

      protected void map( WritableComparable key,
                        HCatRecord value,
                        org.apache.hadoop.mapreduce.Mapper<WritableComparable, HCatRecord,
                        NullWritable, IntWritable>.Context context)
          throws IOException, InterruptedException {
          // The group table from /etc/group has name, 'x', id
        //  groupname = (String) value.get(0);
          int id = (Integer) value.get(1);
          // Just select and emit the name and ID
          context.write(null, new IntWritable(id));
      }
  }

Main class

public class mapper1   {


    public static void main(String[] args) throws Exception {
    mapper1 m=new mapper1();
        m.run(args);
    }

    public void run(String[] args) throws IOException, Exception, InterruptedException {
    Configuration conf =new  Configuration();


    // Get the input and output table names as arguments
    String inputTableName = args[0];

    // Assume the default database
    String dbName = "xademo";

    Job job = new Job(conf, "UseHCat");
    job.setJarByClass(mapper1.class);
    HCatInputFormat.setInput(job, dbName, inputTableName);

    job.setMapperClass(Map.class);

    // An HCatalog record as input
    job.setInputFormatClass(HCatInputFormat.class);

    // Mapper emits a string as key and an integer as value
    job.setMapOutputKeyClass(NullWritable.class);
    job.setMapOutputValueClass(IntWritable.class);


    FileOutputFormat.setOutputPath((JobConf) conf, new Path(args[1]));


    job.waitForCompletion(true);
    }
}

Is there anything wrong in this code?

This is giving some error as Numberformat exception from string 5s. I am not sure where it is being taken from. Showing error at below line HCatInputFormat.setInput()
