hi @Mamy D

have you checked the ambari-server.out file mentioned in the error message for additional detail that may reveal the root cause?

@Mamy D

it's hard to tell with provided information.

plz provide more details like

Ambari server version:

HDP Stack version:

Is mysql up and running?

which sql connector are you using? run below command and provide output

ls -lrt /usr/share/java/mysql-connector-java*

copy last 20 lines error message from amabri-server log, run below command for that.

tail -20 /var/log/ambari-server/ambari-server.log

Thanks,

Divakar

Hi thank you so much for your help.Actually, the issue was due to the Ambari Database.I reminded that I accidently dropped the Ambari Database.So I re-installed the Database and now everything working well. Thank you 🙂
