STDERR
Connection to hadoop2 closed.
Registering with the server...
Registration with the server failed.

--------------------------

Questions:
- why does Ambari not install missing packets (get the required repo, yum clean all, yum install
"foo" -y)
- what causes Ambari server to think there is not agent, when the agent say "No commands from
server"?

Thoughts?

Best,
 Alex
