Hi @prswamy t, please follow the steps from here:

  • Login into Ambari Server host.
  • Clear the database. At the command line, type: "ambari-server reset"
  • Clear your browser cache.
  • Re-run the Install Wizard.

Hi @prswamy t

After ambari reset run host cleanup script and following yum remove commands on all hosts

python /usr/lib/python2.6/site-packages/ambari_agent/HostCleanup.py --silent

yum remove zookeep*

yum remove hdp-select hdp*

Now you are good to restart the installation.

@prswamy t

May be you should first find why they are not running and identify the root cause - else you might hit upon the same issue post re-installation.
