I am tired, Error, Not a host:port pair: local
Hello,
I am following this blog,
http://www.michael-noll.com/wiki/Running_Hadoop_On_Ubuntu_Linux_%28Single-Node_Cluster%29,
instructions to get single hadoop node running. Unfortunately, I am getting
NullPointerException when I start hadoop with ./start-all.sh.
Another question I have is regarding hadoop-site.xml, where I have set
hadoop.tmp.dir to be /home/hadoop/hadoop-datastore. But hadoop is creating
dfs in /tmp/hadoop-hadoop/dfs?

Are you sure that hadoop-site.xml in your config directory/modified by
you is being used, not some default?
