As I set the password for the ambari server, the shell showed that 'Ambari Server 'start' completed successfully', and the postmaster, ambari-server is running, but I got problem when logging into ambari web UI (127.0.0.1:8080), the browser provide with the login interface requires you to input username (admin) and password(I set myself), but after input this information, the ambari UI will not show, instead, the login interface will show again without showing any error message or successful message, seems like I have input nothing. What may cause this problem? And how can I solve it? thanks! ... View more
