Hi,

I have done setup numerous times but this time i did after some break.

I managed to get the cluster up and running fine but when I do  hadoop dfs
-ls /

it actually shows me contents of linux file system

I am using hadoop-1.0.3 on rhel5.6

Can anyone suggest what I must have done wrong?

Hi Nitin

It's likely that your hadoop command isn't finding the right configuration.
In particular it doesn't know where your namenode is
(fs.default.namesetting in core-site.xml)

Maybe you need to set the HADOOP_CONF_DIR environment variable to point to
your conf directory.

Hi Nitin,

Normally your conf should reside in /etc/hadoop/conf (if you don't have one. Copy it from the namenode - and keep it sync)

hadoop (script) by default depends on hadoop-setup.sh which depends on hadoop-env.sh in /etc/hadoop/conf

Or during runtime specify the config dir

i.e:

[hdfs]$  hadoop [--config <path to your config dir>] <commands>

P.S. Some useful links:

I managed to solve this by moving contents on hdfs-site.xml to
core-site.xml
Thanks
