Демон Datanode не работает в Hadoop 2.5.0

Я устанавливаю Hadoop 2.5.0 на одну машину, у меня проблема с узлом данных, который не работает, как показано в выводе команды jps:

$ jps
3404 Jps
2661 NodeManager
2606 ResourceManager
2484 NameNode

Когда я пытаюсь запустить его вручную, я получаю следующее:

$HADOOP_HOME/sbin/hadoop-daemon.sh start datanode
starting datanode, logging to /home/arbi/Programs/hadoop-2.5.0/logs/hadoop-arbi-datanode-ElOued.out

Тогда еще ничего, вот содержимое hadoop-arbi-datanode-ElOued.out:

Также в http://oued.souf.dz:50070/dfshealth.html#tab-datanode нет видимого узла данных.

И когда я отправляю задания Hadoop, я вижу следующее исключение:

14/08/26 17:41:59 WARN mapreduce.JobSubmitter: Hadoop command-line option parsing not performed. Implement the Tool interface and execute your application with ToolRunner to remedy this.
