unable to check nodes on hadoop
If I type 'http://localhost:50070' or 'http://localhost:9000' to see the
nodes,my browser shows me nothing I think it can't connect to the server. I
tested my hadoop with this command:
hadoop jar hadoop-*test*.jar TestDFSIO -write -nrFiles 10 -fileSize 1000
but too didn't work and it tries to connect to the server,this is the
output:
12/06/06 17:25:24 INFO mapred.FileInputFormat: nrFiles = 10
12/06/06 17:25:24 INFO mapred.FileInputFormat: fileSize (MB) = 1000

I changed some files like this: in conf/core-site.xml:
<configuration>
<property>
<name>fs.default.name</name>
<value>hdfs://localhost:9000</value>
</property>
in conf/hdfs-site.xml:
<configuration>
<property>
<name>dfs.replication</name>
<value>1</value>
</property>
</configuration>
</configuration>
in conf/mapred-site.xml:
<configuration>
<property>
<name>mapred.job.tracker</name>
<value>localhost:9001</value>
</property>
</configuration>
but no effect !Have you any Idee,How can I solve my problem?

By default the logs are in /var/log/hadoop or /var/logs/hadoop
Which mode are u running? Standalone? Pseudo distributed? Distributed?

Thank you for your answer,where is the log of namemode?How can I control it?
if I type hadoop -version as result I have:
java version "1.6.0_26"
Java(TM) SE Runtime Environment (build 1.6.0_26-b03)
Java HotSpot(TM) Server VM (build 20.1-b02, mixed mode)
and I downloaded hadoop 0.20.2

Babak,
Probably, your namenode is not up. Check the logs of namenode first.
Also, please specify the version? the mode in which you are running hadoop?
