No Services Running on Practice Exam

[#1]

When I set up the Amazon Instance I followed the directions on the Java Developer Practice Exam except for Network type (which I assume to be the problem), because Classic-EC2 was not an option for me, I just went forward with the only option that I had.

When I'm on the instance Ambari shows lost heartbeat to all of the services and I cannot access the hdfs file system which gives me an Exception that the connection was lost to the namenode.

Extra info. The only option I have is the vpc network.

Make sure you are not using the free EC2 instance type - it is not big enough to run HDP. Log in and try restarting the Ambari agent, and then run the start_all_services.sh script:

# ssh namenode "ambari-server restart"
# /root/start_all_services.sh

Let me know if that works for you.
