Hallo everyone,
I have installed the hadoop 0.18.3 on three linux machines, I am trying to
run the
example of WordCountv1.0 on a cluster. But I guess I have a problem
somewhere.
*
Problem*
*After formating the name node:*
I am getting several STARTUP_MSG and at the end a "SHUTDOWN_MSG: shutting
down the namenode..."
is this normal?
*Afterwards I try starting the dfs:**
*I get a message "starting namenode..."* *afterwards I get another message
"starting secondary namenode"
at this stage the shell is blocked unless I press the enter key. Then the
system tries to start another secondary
namenode and the shell is then not blocked. What is going on?
*
Then I proceed an try starting the mapred:*
I get the two messages "starting jobtracker....." and "starting tasktracker"
*Following the tutorial for runnin WordCode v1.0, If I try to list the files
in the input folder I have created
*I get the famous error "Retrying connect to server:134.130.222.20:9000"
.what am I doing something wrong?
*Steps I have already verified*
*I have already checked the iptables of the three machines and they look**:
**
*Chain INPUT (policy ACCEPT)
target prot opt source destiantion
Chain FORWARD (policy ACCEPT)
target prot opt source destination
Chain OUTPUT (policy ACCEPT)
target prot opt source destination
*
My hadoop-site.xml file looks like this
* configuration>
<property>
<name>fs.default.name</name>
<value>134.130.222.20:9000/</value>
</property>
<property>
<name>mapred.job.tracker</name>
<value>134.130.222.18:9001</value>
</property>
........
</configuration>
*Can someone help me out?*
*Thank you, CJ*
