Hi Guys:
I am just installation the hadoop 0.21.0 in a single node cluster.
I encounter the following error when I run bin/hadoop namenode -format
10/12/08 16:27:22 ERROR namenode.NameNode:
java.io.IOException: Cannot create directory
/your/path/to/hadoop/tmp/dir/hadoop-hadoop/dfs/name/current
Hi Richard -
First thing that comes to mind is a permissions issue. Can you verify that
your directories along the desired namenode path are writable by the
appropriate user(s)?
HTH,

I verified that I have the following permission set for the path:
ls -l tmp/dir/hadoop-hadoop/dfs/hadoop
total 4
drwxr-xr-x 2 hadoop hadoop 4096 2010-12-08 15:56 current
Thanks.

would that be the reason that 54310 port is not open?
I just used
* iptables -A INPUT -p tcp --dport 54310 -j ACCEPT
to open the port.
But it seems the same erorr exists.

it seems that you are looking at 2 different directories:
first post: /your/path/to/hadoop/tmp/dir/hadoop-hadoop/dfs/name/current
second: ls -l tmp/dir/hadoop-hadoop/dfs/hadoop

Hi:
/your/path/to/hadoop represents the location where hadoop is installed.
BTW, I believe this is a file writing permission problem. Because I use the
same *-site.xml setting to install with root and it works.
But when I use the dedicated user hadoop, it always introduces this problem.
But I do
Yeah, I figured that match. What I was referring to is the ending of the paths:
.../hadoop-hadoop/dfs/name/current
.../hadoop-hadoop/dfs/hadoop
They are different

oh, sorry. I corrected that typo

Even I remove the tmp I manually created and set all the Hadoop package to
be 777. Then I run
