Errori di "Autorizzazione negata" all'avvio di un cluster a nodo singolo in Hadoop

Sto lavorando in Ubuntu 10.10 e sto cercando di avviare un cluster a nodo singolo in Hadoop.

Non ho idea di cosa stia facendo di sbagliato o cosa suggeriscano alcuni di questi errori.

hadoop@abraham-Dimension-3000:/usr/local/hadoop$ jps
5099 Jps

Chiunque può diagnosticare il problema.

Gli errori suggeriscono un problema di autorizzazioni.

Assicurati che l'utente hadoop disponga dei privilegi adeguati /usr/local/hadoop. Provare:

sudo chown -R hadoop / usr / local / hadoop /

hai specificato la directory di lavoro per il file system hadoop con un utente diverso da quello di hadoop, quindi imposta la directory che ha letto, scrivi le autorizzazioni per l'utente di hadoop o modifica il ower della directory
Try ::

sudo chown -R hadoop-user /user/hadoop_project/

o

sudo chmod 777 /user/hadoop_project

dove nome utente 'hadoop-user' per l'ambiente hadoop. 'hadoop-project' ha specificato la directory di lavoro per il file system hadoop. (specifica il tuo login e la tua directory che stai usando per l'installazione di hadoop)
