title: $HADOOP_HOME is deprecated
body: <p>I started a hadoop cluster.<br>
  I get this warning message: <code>$HADOOP_HOME is deprecated</code>      </p>
  
  <p>I already add <code>export HADOOP_HOME_WARN_SUPPRESS="TRUE"</code> into <code>hadoop-env.sh</code><br>
  When I started the cluster, I do not see any more warning message.<br>
  However, When I run <code>hadoop dfsadmin -report</code>, It shows again.    </p>
