Installing Hadoop -- export JAVA_HOME=/usr/java/latest

I am following instructions on website to install Hadoop. However, I am stuck on the "# set to the root of your Java installation export JAVA_HOME=/usr/java/latest " part. How do I figure out the root on Ubuntu?

set to the root of your Java installation

Above statement is saying you to point to the jdk installation folder. Lets say you have jdk extracted to /opt/java/ as jdk1.8.0_60 then the export option should be 

export JAVA_HOME=/opt/java/jdk1.8.0_60

But if you have installed java using ubuntu commands then you can find the java installed path with whereis or which commands. for example 

$ which java
/usr/bin/java

Which showed that java is installed in /usr/bin/java so your export line should be 

export JAVA_HOME=/usr

But I suggest you to follow the first step by downloading the appropriate version of java, and following the first way I mentioned above.

Hope the answer is helpful
