How to start the hadoop which i just install ,rather than the former version

Question

I want to installed the hadoop(3.2) in my linux system which has installed the hadoop(2.7).When I execute hadoop , I can only get the information of hadoop 2.7 ,even if I change the environment variable. And the most confused thing is when I run echo $HADOOP_HOME , sometimes I can get the path of hadoop 2.7,sometimes hadoop 3.2. I hope someone can help me.
