First You may have to add your HADOOP_HOME variable in .bashrc file .
for examplel:

export HADOOP_HOME=/usr/local/bigdata/hadoop/hadoop-1.2.1
export CLASSPATH=$JAVA_HOME:/usr/local/bigdata/hadoop/hadoop-1.2.1/hadoop-core-1.2.1.jar
export PATH=$PATH:$HADOOP_HOME/bin  

Then open a new session and execute ./start-all.sh

then run your commands again.
