Hadoop: «ERROR : JAVA_HOME is not set»

Question

I\'m trying to install Hadoop on Ubuntu 11.10. I set the JAVA_HOME variable in the file conf/hadoop-env.sh to:

# export JAVA_HOME=         


        

Answer 1

Here we provide simple steps to setup JAVA_HOME while installing of Hadoop

Step1: Goto Java library path /lib jvm

Then set the JAVA_HOME & PATH in .bashrc file

Step 2 : Once it is done then go with Hadoop env file then update it.

After once it is done then stop the daemons and start daemons once again.
