Re: Hadoop 2.6.0 Error
Mr. Reddy:
I tried both options, and it does not work. starting daemons fail with
JAVA_HOME not set error. However, if I $ECHO JAVA_HOME it points to the RIGHT
directory. Have you worked on a lower version of Hadoop, I see that on the
website they just have 1.2, 2.5 and 2.6. 1.2 does not have Yarn support. Is 2.5
stable. Path errors are a major issue in hadoop.
Thanks for your suggestions.

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.

Re: Hadoop 2.6.0 Error
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

/usr/local/hadoop/etc/hadoop/hadoop-env.sh export
JAVA_HOME='/usr/lib/jvm/java-7-openjdk-amd64' It would resolve your error.
