I'm trying to setup hadoop using these guides:
http://wiki.apache.org/nutch/NutchHadoopTutorial and
http://www.nabble.com/Nutch-Step-by-Step-Maybe-someone-will-find-this-useful---tf3526281.html
But i'm stuck at the early step: having a single machine running.
using nutch 0.8.1 and so the provided hadoop "hadoop-0.4.0-patched.jar"
JVM sun 1.5.0_11
When I start the namenode (using ./bin/start-all.sh) I have this in the
namenode-log:
2007-05-02 12:39:51,335 INFO util.Credential - Checking Resource aliases

and after I can't access it:
$ ./bin/hadoop dfs -ls
ls: Connection refused
hadoop.log:

[...]
1. I can't understant why there is this FileNotFound execption, I didn't
change anything in the hadoop nutch jar file.
2. It looks like the namenode is running (when I stop it I have the message
"stopping namenode"), but why I can't access it ? (is this ip from the log
correct? 0.0.0.0:50070)
all is on the same machine, and my conf file looks ok:
fs.default.name myhostname:9000
mapred.job.tracker myhostname:9001
mapred.map.tasks 2
mapred.reduce.tasks 2
dfs.name.dir /home/nutch/filesystem/name
