Thanks Tom,
well now that is strange. I will look into that again. I suspect some classpath/eclipse problems here.

Hi Martin,

Neither Tool nor ToolRunner is deprecated in 0.21.0. I don't think
they have ever been deprecated. You should be able to use them without
problems.

Hello,
I am trying to move to Hadoop MapReduce 0.21.0.
The corresponding tutorial still uses Tool and ToolRunner.
Yet both are deprecated. What would be the correct way to implement,
configure and submit a Job now? I was thinking in terms of:
     Configuration configuration = new Configuration();         Cluster
cluster = new Cluster(configuration);     Job job =
Job.getInstance(cluster);
     job.setJarByClass(WordCount.class);     job.setMapperClass(Map.class);
     job.setCombinerClass(Reduce.class);
job.setReducerClass(Reduce.class);     job.setOutputKeyClass(Text.class);
     job.setOutputValueClass(IntWritable.class);
     FileInputFormat.addInputPath(job, new Path(INPUT));
FileOutputFormat.setOutputPath(job, new Path(OUTPUT));
     System.exit(job.waitForCompletion(true) ? 0 : 1); Thanks in advance,
Martin
