Hadoop map throw "Filesystem closed" exception - hadoop

Question

I'm running a MapReduce task against Wikipedia dump with history using XmlInputFormat for parsing the XML.
"xxx_m_000053_0" always stop at 70% before it's kill due to time out.
in the console:
xxx_m_000053_0 failed to report status for 300 seconds. Killing!
I increase the timeout to 2 hours. It didn't work.
In xxx_m_000053_0 log file:
Processing split: hdfs://localhost:8020/user/martin/history/history.xml:3556769792+67108864
I was expecting something wrong in history.xml in offset [3556769792,3623878656]. I split the file from this offset and run it in hadoop. It worked... (???)
In xxx_m_000053_0 log file:

So I'm thinking it might be a configuration problem? Why is my file system stop?
Something wrong with XmlInputFormat ?
My empty mapper:
#Override
public void map(LongWritable key, Text value, Context context) throws IOException, InterruptedException
{
//nothing to do...
}
My Main:
public static void main(String[] args) throws IOException, ClassNotFoundException, InterruptedException {
Configuration conf = new Configuration();
conf.set("xmlinput.start", "<page>");
conf.set("xmlinput.end", "</page>");
Job job = new Job(conf, "wikipedia link history");
job.setJarByClass(Main.class);
job.setMapperClass(Map.class);
job.setReducerClass(Reduce.class);
job.setInputFormatClass(XmlInputFormat.class);
job.setMapOutputKeyClass(Text.class);
job.setMapOutputValueClass(IntWritable.class);
job.setOutputKeyClass(Text.class);
job.setOutputValueClass(Text.class);
job.setOutputFormatClass(TextOutputFormat.class);
FileInputFormat.addInputPath(job, new Path(args[0]));
FileOutputFormat.setOutputPath(job, new Path(args[1]));
boolean result = job.waitForCompletion(true);
System.exit(result ? 0 : 1);
