As per the error, you need to check the logs to understand what's happening. The log is /var/log/ambari-server/ambari-server.log

If it doesn't make sense - don't hesitate to post them here.

Hi @ANSARI FAHEEM AHMED ,

looks like you are using MySQL as underlying db, and you need to set property 'max_allowed_packet' in mysql config file.

With a default installation, it would be in file /etc/my.cnf , where you can add/set the property like e.g.:

max_allowed_packet=256M

Then restart mysql and give the ambar-server start another try.

HTH, best regards
