I have installed hadoop 1.0.1 in my ubuntu laptop by a deb install file. the hadoop files are install into different directories, eg: config file are installed into /etc/hadoop, but the bin files are installed into /usr/sbin. So how can I specifiy the HADOOP_HOME?

HADOOP_HOME is the parent directory of the bin directory that holds the Hadoop scripts. see Getting started with Hadoop

I would not set HADOOP_HOME in this case. I am using 1.0.4 deb installation on Ubuntu as well, and the only *HOME I set is JAVA_HOME in /etc/hadoop/hadoop-env.sh
