Hello Anand,

 

Set your Java home in hadoop-env.sh = - /usr/local/hadoop/etc/hadoop/hadoop-env.sh

 

export = JAVA_HOME=3D'/usr/lib/jvm/java-7-openjdk-amd64'

 

It would resolve your error.

Hello,

 

I had a similar problem and my solution to this was setting JAVA_HOME = in /etc/environment.

 

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 = =E2=80=98ls -la=E2=80=99 ) 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.

 

For more info see http://stacko= verflow.com/questions/216202/why-does-an-ssh-remote-command-get-fewer-env= ironment-variables-then-when-run-man, or man bash

 

Thank you,
