> In JobClient:
> {code}
> public RunningJob submitJobInternal(final JobConf conf)
>       throws FileNotFoundException, IOException {
>     try {
>       conf.setBooleanIfUnset("mapred.mapper.new-api", false);
>       conf.setBooleanIfUnset("mapred.reducer.new-api", false);
>       Job job = clientUgi.doAs(new PrivilegedExceptionAction<Job> () {
>         @Override
>         public Job run() throws IOException, ClassNotFoundException, 
>           InterruptedException {
>           Job job = Job.getInstance(conf);
>           job.submit();
>           return job;
>         }
>       });
>       // update our Cluster instance with the one created by Job for submission
>       // (we can't pass our Cluster instance to Job, since Job wraps the config
>       // instance, and the two configs would then diverge)
>       cluster = job.getCluster();
>       return new NetworkedJob(job);
>     } catch (InterruptedException ie) {
>       throw new IOException("interrupted", ie);
>     }
>   }
> {code}
> We will replace the cluster object with the cluster object from Job, but the previous
old cluster object would never be closed.
