Please could you give some details. Is the databse up and running?

- Operating System

- HDP version
- Fresh Install or Upgrade.

Hi @Geoffrey Shelton Okot,

Operating System : CentOS 6.6

Ambari Version = 2.5.0.3

HDP Version = 2.3

Upgrading from 2.2*

Database is up running..

After upgrade it was working fine. I have installed urllib python package in my system and ambari-agent in the edge node stopped working due to module conflict. So i removed urllib package and ambari-agent started working, after restart I tried to start the server and those above mentioned error occurred.

Thanks

Ashik
