Sumit Mohanty commented on AMBARI-11940:
----------------------------------------

All relevant server side unit tests passed. Manually tested and verified that retry is only used for the initial phase of cluster install and add host.

> The automatic retry of the tasks at the agent should be limited to the initial INSTALL and START commands only.
> Retry is only needed during the initial install using blueprints to get around the lack of role command order enforcements. Beyond the initial install/start automatic retry can actually be hinderance to debugging errors. While it is possible to modify {{cluster-env}} to disable this capability, by default disabling auto-retry post initial INSTALL/START makes more sense.
