Not able to login to Ambari dashboard

Hi,

I downloaded the HDP 2.3 VM.

I was using it perfectly fine. But many times I would shutdown the machine with Poweroff option of VM.

Now I am not able to login to Ambari dashboard.

I have uploaded the video here (1.5 mins)  to show the issue

I have tried the following

• sudo service ambari-server restart
• sudo service ambari-agent restart
• sudo /etc/init.d/postgresql restart

All service i can see says OK in terminal.

However when i login on dashboard

http://127.0.0.1:8080 with username password admin/admin

The dashboard just does not allow me to login. It stays at the same page after refreshing once.

• How to fix this issue.
• What is the correct step to stop VM.

Thanks,
