Description

Steps to reproduce :

1) Create a healthy cluster
2) Stop a service and delete it(say Kafka or Zookeeper)
3) Try to reinstall the same service and the action fails.

Seeing below error in ambari-agent.log

Attaching the screenshot.

I have tried the same action for Zookeeper and it fails with similar exception.
