Hello,
I am installing hadoop according to this page:
https://cwiki.apache.org/BIGTOP/how-to-install-hadoop-distribution-from-bigtop.html
I think I have successfully installed hadoop on my Ubuntu 12.04 x64.
Then I go to step Running Hadoop, bellowing is my operation step,
why it prompts that my JAVA_HOME is not set?
------------------------------------------------------------------------------------------
root@ubuntu32:/usr/lib/hadoop# export
JAVA_HOME=/usr/lib/jvm/java-7-openjdk-i386/jre/bin/java
root@ubuntu32:/usr/lib/hadoop# sudo -u hdfs hadoop namenode -format
Error: JAVA_HOME is not set.
root@ubuntu32:/usr/lib/hadoop# ls $JAVA_HOME -al
-rwxr-xr-x 1 root root 5588 May 2 20:14
/usr/lib/jvm/java-7-openjdk-i386/jre/bin/java
root@ubuntu32:/usr/lib/hadoop#
