If you put the variables in /etc/environment then it will be available to all users on the operating system. HDFS doesn't run with root privileges. You need to open the application with *sudo* or with root privileges to modify it. e.g. If you are using vi editor then its just *sudo* *vim /etc/environment* (similar, if you are using other editors) and add environment variables there.
