No, it is not normal. You should click on the "Warning encountered" link to see what went wrong (Ignoring these warnings and clicking to "Next" may have some consequences later). It will also be good to take a look at your ambari server logs to see if there is any warning/error.

Looking at the Agent logs of that particular host also will give us more idea.

I will suggest that you try to start those services one by one. Like try starting HDFS services first then try YARN services.

One by one starting services will help in finding where we meet the resource limitation. Also we can keep checking the logs to find out what is going wrong if the service startup fails.

Other services which you do not want to use immediately (might have installed just for testing), you can put them in "Maintenance Mode" So that you won't see the alerts.
