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.
Thanks

{}-->Hello Anand, Set your Java home in hadoop-env.sh -
/usr/local/hadoop/etc/hadoop/hadoop-env.sh export
JAVA_HOME='/usr/lib/jvm/java-7-openjdk-amd64' It would resolve your error.

Subject: RE: Hadoop 2.6.0 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 ‘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. For more info see
http://stackoverflow.com/questions/216202/why-does-an-ssh-remote-command-get-fewer-environment-variables-then-when-run-man,
or man bash Thank you,Alex From: Olivier Renault

Subject: RE: Hadoop 2.6.0 Error HI
Ideally it should take effect , if you configure in .profile or hadoop-env.sh..
As you told that you set in .profile ( hope you did source ~/.profile ),,,
did you verify that take effect..? ( by checking echo $JAVA_HOME,, or
jps..etc )... Thanks & Regards Brahma Reddy Battula From: Anand Murali
