Dear Mr.RagavendraGanesh I did first try setting JAVA_HOME to the JDK path in hadoop-env.sh. It still does not work. I have been looking for lower versions of Hadoop on apache, but they have removed them except 1.X, which is antiquated. Suggestions welcome.

The problem is, from what I remember, that the start-dfs.sh script calls hadoop-daemons.sh with the necessary options to start the Hadoop daemons. hadoop-daemons.sh in turn calls hadoop-daemon.sh with the necessary options via ssh, in an non-interactive fashion. When you are executing a command via ssh in a non-interactive manner (ex. ssh host1 ‘ls -la’ ) you have a minimal environment and you do not source the .profile file, and other environment related files. But the /etc/environment is sourced so you could set JAVA_HOME there. Technically you should set BASH_ENV there which should point to a file containing the environment variables you need.
