Testing the well functionality of hadoop might need large storage as 
hadoop is designed for big data:)
But at this moment I am not quite sure what exactly need to be tailored 
for hadoop case. I will come back
to this as soon as I figured it out.

I will add another hypervisor host. Is there any network requirement 
for the management server and hypervisor host?

May I know how does the management server know the hypervisor host and 
include it to its management?

Yes, this step works for me.

I create a file named under utils/conf. Put my 
root password inside it and it works!

The command "mvn -pl :cloud-client-ui jetty:run" gives me a 
error:[INFO] Couldn't find specified project dir: 

I notice that there is no cloud-client-ui directory under cloudstack. 
So I switched to "mvn -pl client jetty:run", however it told me the 
maven-jetty-plugin does not exist.

[INFO] Searching repository for plugin with prefix: 'jetty'.
[INFO] The plugin 'org.apache.maven.plugins:maven-jetty-plugin' does 
not exist or no valid version could be found

Any light on this?
