Open your bash profile (~/.profile or ~/.bash_profile) for editing and add the following:

1. export HADOOP_HOME="/usr/local/Cellar/hadoop" then Replace with your own path

2. export HADOOP_CLASSPATH=$(find $HADOOP_HOME -name '*.jar' | xargs echo | tr ' ' ':') Save the changes and reload.

3. source ~/.profile
