DataDrivenInputFormat setInput with boundingQuery

[Edward Capriolo]

I am working with DataDrivenOutputFormat from trunk. None of the unit
tests seem to test the bounded queries

Configuration conf = new Configuration();
                Job job = new Job(conf);
                job.setJarByClass(TestZ.class);

                job.setInputFormatClass(DataDrivenDBInputFormat.class);
                job.setMapperClass(PrintlnMapper.class);
                job.setOutputFormatClass(NullOutputFormat.class);
                job.setMapOutputKeyClass(NullWritable.class);
                job.setMapOutputValueClass(NullDBWritable.class);
                job.setOutputKeyClass(NullWritable.class);
                job.setOutputValueClass(NullWritable.class);

                job.setNumReduceTasks(0);

                job.getConfiguration().setInt("mapreduce.map.tasks", 2);

                DBConfiguration.configureDB(conf, "com.mysql.jdbc.Driver",
                                "jdbc:mysql://localhost:3306/test", null, null);

                DataDrivenDBInputFormat.setInput(job, NullDBWritable.class,
                                "SELECT * FROM name WHERE $CONDITIONS",
                                "SELECT MIN(id),MAX(id) FROM name");
                int ret = job.waitForCompletion(true) ? 0 : 1;

Exception in thread "main" java.lang.RuntimeException:
java.lang.RuntimeException: java.lang.NullPointerException
        at 
org.apache.hadoop.mapreduce.lib.db.DBInputFormat.setConf(DBInputFormat.java:165)

Can someone tell me what I am missing here?
Thanks,
Edward
