pb lancement hadoop sous ubuntu 11.10

Question

Bonjour,  

J'ai installer hadoop sous ubuntu 11.10 avec le jdk java6u25 
$ java -version 
java version "1.6.0_25" 
Java(TM) SE Runtime Environment (build 1.6.0_25-b06) 
Java HotSpot(TM) Server VM (build 20.0-b11, mixed mode) 

j'ai crée un tunnel ssh et un utilisateur hadoop que j'ai appelée hduser pour la connexion en local. 
j'ai créé le système de fichier avec la commande hadoop namenode -format et tout c'est bien passé sans messages d'erreurs. 
Après j'ai modifier les fichier de configurations *-sites.xml en suivant le tutorial. 

Enfin, j'ai voulu lancer hadoop avec all-start.sh à partir du compte hduser mais il y a une erreur qui m'empêche de le faire et j'ai aucune idée comment corriger le problème . voilà le résultat : 


~$ /usr/local/hadoop/bin/start-all.sh 
starting namenode, logging to /usr/local/hadoop/bin/../logs/hadoop-hduser-namenode-ramzi-RV409-RV509-RV709.out

j'espère avoir votre aide .  
merci d'avance,
