franklinsijo:
Le travail MapReduce échoue parce qu'il est incapable de HDFS d'accès depuis There are 0 datanode(s) running and 0 node(s) are excluded in this operation.
Et à partir des journaux de DataNode, il est entendu que le Datanodedémon est incapable de s'inscrire auprès du groupe en raison de HDFS Incompatible clusterIDs.
Lorsqu'un NameNode est formaté (lors de l' installation et la configuration), un clusterIDest généré et ce clusterid est stocké dans le VERSIONfichier de chaque démon quand ils initialize. Ce clusterid agit comme identifiant pour les DataNodes, leur permettant de rejoindre le cluster quand ils sont arrêtés et ont commencé.
Incompatible clusterIDs entre les nœuds peuvent se produire lorsque le NameNode est formaté sur un cluster actif et les autres daemons ne sont pas réinitialisée.
Pour obtenir le retour du cluster sous forme,
- Arrêtez le cluster
- Supprimez le contenu des répertoires suivants
C:\hadoop\hdfstmp,C:\hadoop\data\namenode,C:\hadoop\data\datanode - Format du NameNode
- Démarrez le cluster
Vous avez recopie les données requises pour le poste MapReduce et exécuter le travail.
