Can anyone offer me some insight. It may have been due to me trying to run the start-all.sh script instead of starting the services. Not sure.

Thanks

Hello Sean,

Welcome to the hadoop mailing lists, and thanks for asking your
question supplied with good data!

Moving this to cdh-user@cloudera.org list as you're using the CDH3
version of Apache Hadoop. (bcc'd common-user@hadoop.apache.org and
cc'd you)

Some questions below:

- Can you run "sudo -u hdfs df -kh /var/lib/hadoop-0.20/cache/dfs"?
What does the output carry?

To start hadoop I do:


$ for service in /etc/init.d/hadoop-0.20-*

running "sudo -u hdfs df -kh /var/lib/hadoop-0.20/cache/dfs"

Also, please paste contents of your hdfs-site.xml and core-site.xml? I
believe I have reproduced this issue and found a solution, and would
like to confirm.
