It's normal that they are all empty. Look at files with .log extension.

gt; Try looking at namenode logs (under logs directory). There should
be
gt; an exception. Paste it here if you don't understand what it means.

Cannot access Jobtracker and namenode

2009-04-12 Thread halilibrahimcakir


Hi

I am new at hadoop. I downloaded Hadoop-0.19.0 and followed the
instructions in the quick start
manual(http://hadoop.apache.org/core/docs/r0.19.1/quickstart.html). When I
came to Pseudo-Distributed Operation section there was no problem but
localhost:50070 and localhost:50030 couldn't be opened. It says localhost
reffused the connection. I tried this in another machine, but it says
like Http Error 404: /dfshealth.jsp  How can I see these pages and
continue using hadoop? Thanks.

Additional Information: 

OS: Debian 5.0 (latest version)
JDK: Sun-Java 1.6 (latest version)
 rsync and ssh installed
edited hadoop-site-xml properly

Yes, usually when I type ssh localhost in terminal.

Does your system request a password when you ssh to localhost outside
hadoop?

I typed:

$ ssh-keygen -t dsa -P '' -f ~/.ssh/id_dsa
$ cat ~/.ssh/id_dsa.pub gt;gt; ~/.ssh/authorized_keys

Deleted this directory:

$ rm -ri /tmp/hadoop-root

Formatted namenode again:

$ /bin/hadoop namenode -format

Stopped:

$ /bin/stop-all.sh


then typed:



$ ssh localhost

so it didn't want me to enter a password. I started:

$ /bin/start-all.sh

But nothing changed :(
