Hadoop and Ambari alerts (Sandbox)

I am trying to make a virtual environment with Oracle VM Virtualbox to use the Hadoop Environment... everything seems to work fine but then I find 26 alerts... The system does not allow me to fix the alerts... Somebody nows what is going on?

Solution

You need to start everything and allow some times for alert states to reset. Additionally, you have a bunch of services in maintenance mode which may have already thrown an alert before maintenance mode. Last but not least, having all of services installed in same sandbox, I assume single node, can cause some of them to throw alerts and errors as the environment is not sufficient to operate everything at the same time.
