$which java
make sure the paths are valid for your installation (change if using 32bit version):
/usr/lib/jvm/java-6-openjdk-amd64/jre/bin/java
/usr/lib/jvm/java-6-openjdk-amd64/bin/javac
Setup update-alternatives:
sudo update-alternatives --install "/usr/bin/java" "java" "/usr/lib/jvm/java-6-openjdk-amd64/jre/bin/java" 1
sudo update-alternatives --install "/usr/bin/javac" "javac" "/usr/lib/jvm/java-6-openjdk-amd64/bin/javac" 1
sudo update-alternatives --set java /usr/lib/jvm/java-6-openjdk-amd64/jre/bin/java
sudo update-alternatives --set javac /usr/lib/jvm/java-6-openjdk-amd64/bin/javac
Alternatively, make sure the correct version is checked for both Java and compiler:
sudo update-alternatives --config java
sudo update-alternatives --config javac
List the installed Java alternatives with:
sudo update-alternatives --list java
sudo update-alternatives --list javac

Hi,
Creating batch program will not have the same effect. 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.

Mr. Ravindra:
This is visible, however I am unable to modify it, eventhough I have admin priveleges. I am new to the Linux environment. Shall be glad if you did advise. However, as I told you earlier, I have created a batch program which contains, JAVA_HOME setting, HADOOP_INSTALL setting and PATH setting. I have rfun this file but I am still unable to start the daemons. I am following Tom Whyte's -Hadoop definitive Guide book instructions on how to install Hadoop.
at $hadoop version works. I am able to format namenode, but fail to start daemons.
Reply most welcome.

I am using Ubuntu 14. Can you please provide the full path. I am logged in as root and it is not found in /etc. In any case what you have suggested I have tried creating a batch file and it does not work in my installation.

I dont find any etc/environment. Can you be more specific please. I have done whatever you are saying in a user created batch program and run it, followed by running hadoop-env.sh and it still does not work.

Hi,
If you are using Ubuntu then add these lines to /etc/environment
JAVA_HOME=<actual path to jdk>
PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:$JAVA_HOME/bin"
Please put the actual path to JDK in the first line.

Anand,
Sorry about that, I was assuming Redhat/Centos.
For Ubuntu, try sudo update-alternatives --config java.

Dear Mr.Roland:
The alternatives command errors out. I have the extracted version of the Oracle JDK7. However I am ignorant regarding its installation on Ubuntu. Can you point me to installation material so that I can look up and try.
Thanks

Anand,
My guess is that your alternatives setup isn’t complete.
At a prompt, as su, run the command ‘alternatives - - config java’. Make sure that the oracle version is listed and is marked as the active one.
If it is not, go through the steps to make sure it is.
