500 status code received on POST method for API: /api/v1/stacks/HDP/versions/2.5/recommendations Error message: Server Error

[#1]

First of all thanks to all who answer this question as i am struggling with this issue from many hours but unable to resolve it.

I have HDP2.5 running on my dev environment. After making a cleanup of all services except ZooKeeper i am not able to add any service using Ambari UI. The error message is below:-

500 status code received on POST method for API: /api/v1/stacks/HDP/versions/2.5/recommendations Error message: Server Error

Error screen shot is also attached for reference.

I have restarted the Ambari-server many times but no success.

Thanks again.

Ambari server log will have detailed exception for this issue. Please check what is the complete exception you see in /var/log/ambari-server/ambari-server.log while you are attempting to add a service.

Most probably this might be due to Ambari DB issues which you can identify from ambari-server.log
