Se si digita http://localhost:50070
o http://localhost:9000
per visualizzare i nodi, il mio browser non mi mostra nulla. Penso che non possa connettersi al server. ho provato il mio Hadoop con questo comando:impossibile controllare i nodi su hadoop [Connessione rifiutata]
hadoop jar hadoop-*test*.jar TestDFSIO -write -nrFiles 10 -fileSize 1000
ma troppo non ha funzionato e si tenta di connettersi al server, questo è l'output:

12/06/06 17:25:24 INFO mapred.FileInputFormat: fileSize (MB) = 1000

ho cambiato alcuni file in questo modo: in conf/core-site.xml:
<configuration>
<property>
<name>fs.default.name</name>
<value>hdfs://localhost:9000</value>

in conf/HDFS-site.xml:
<configuration>
<property>
<name>dfs.replication</name>
<value>1</value>

in conf/mapred-site.xml:

Hey thnks ragazzi per la vostra attenzione, Se corro questo comando
cat /etc/hosts
vedo:
127.0.0.1 localhost
127.0.1.1 ubuntu.ubuntu-domain ubuntu
# The following lines are desirable for IPv6 capable hosts
::1 ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
e se eseguo questo:
ps axww | grep hadoop
vedo questo risultato:
2170 pts/0 S+ 0:00 grep --color=auto hadoop
ma nessun effetto Avete qualche Idee, Come posso risolvere il mio problema?
Cosa c'è nel file/etc/hosts? –
Non l'ho trovato, sai, dov'è esattamente il file host? – Baper
nella cartella hadoop? – Baper
