Subject Ynt: Re: Cannot access Jobtracker and namenode
Date Sun, 12 Apr 2009 20:30:00 GMT
I followed these steps:

$ bin/stop-all.sh
$ rm -ri /tmp/hadoop-root
$ bin/hadoop namenode -format
$ bin/start-all.sh

and looked "localhost:50070" and "localhost:50030" in my browser that the
result was not different. Again "Error 404". I looked these files:

$ gedit hadoop-0.19.0/logs/hadoop-root-namenode-debian.out1
$ gedit hadoop-0.19.0/logs/hadoop-root-namenode-debian.out2
$ gedit hadoop-0.19.0/logs/hadoop-root-namenode-debian.out3
$ gedit hadoop-0.19.0/logs/hadoop-root-namenode-debian.out4

4th file is the last one related to namenode logs in the logs directory.
All of them are empty. I don't understand what is wrong.

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

&gt; I typed:
&gt;
&gt; $ ssh-keygen -t dsa -P '' -f ~/.ssh/id_dsa
&gt; $ cat ~/.ssh/id_dsa.pub &gt;&gt; ~/.ssh/authorized_keys
&gt;
&gt; Deleted this directory:
&gt;
&gt; $ rm -ri /tmp/hadoop-root
&gt;
&gt; Formatted namenode again:
&gt;
&gt; $ /bin/hadoop namenode -format
&gt;
&gt; Stopped:
&gt;
&gt; $ /bin/stop-all.sh
&gt;
&gt;
&gt; then typed:
&gt;
&gt;
&gt;
&gt; $ ssh localhost
&gt;
&gt; so it didn't want me to enter a password. I started:
&gt;
&gt; $ /bin/start-all.sh
&gt;
&gt; But nothing changed :(

&gt; There are two commands in hadoop quick start, used for passwordless
ssh.
&gt; Try those.
&gt;
&gt; $ ssh-keygen -t dsa -P '' -f ~/.ssh/id_dsa
&gt; $ cat ~/.ssh/id_dsa.pub &gt;&gt; ~/.ssh/authorized_keys
