The issue was that the ambari was not able to connect to the database which is running on different server.   I turned on the debug option in the ambari.properties file but it didnt tell me this. Leave the ambari server running for the night and unfortunately nothing in the logs.   Could you please guide me if this can improved in the future and where should I report this? I would love to see something like timeout to database or similar message in the logs.   Thanks. ... View more
