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

• hadoop ERROR : JAVA_HOME is not set

Above error is because of the space in between two words.

Eg: Java located in C:\Program Files\Java --> Space in between Program and files would cause the above problem. If you remove the space, it would not show any error.
