I'm not getting the JAVA_HOME error now. I was able to run the example
However, when I run the command hadoop jar
$HADOOP_HOME/hadoop-*-examples.jar wordcount input output1
I get the following output

I'm running the Hadoop on a Google compute engine with 1 SecondaryNameNode<http://220.127.116.11:7180/cmf/services/8/instances/36/status
1 NameNode <http://18.104.22.168:7180/cmf/services/8/instances/34/status
I also want to know where the input and output files are located and how
can I check for logs.

The /etc/hadoop/conf directory is managed by alternatives, so simply
deploying the client configurations will fix it. It's safe to either
leave the package in place or remove it, your choice.

Ok I will try that. But by mistake I installed hadoop-0.20-conf-pseudo

the wrong configuration.
What you want to do instead is to go the CM GUI and tell it to deploy
the client configuration
Please do that and try again.
If you're still having issues, please send more details on how you
installed and what your current configuration looks like (number of
nodes, IP scheme, DNS setup, etc.).

I have several doubts regarding this installation.
Is it true that the manager will install Hadoop on all 8 VMs?
