Hadoop name node format says "JAVA_HOME" not set

Machine: Linux Santiago

Hadoop Version: Apache hadoop 2.7.1

Mode Of Installation: Pseudo Distributed

Done: I downloaded the tar file and just extracted

Checks: I just set my JAVA_HOME in bashrc file and checked by echoing JAVA_HOME. It works.

Stmt which caused error: bin/hadoop namenode -format

Error: JAVA_HOME is not set

Any idea?

Note down the following things

1) Set JAVA_HOME in hadoop-env.sh

2) For newbie, don't forget to export JAVA_HOME

Then Formatting will be successful.
