> Key: AMBARI-13825

> Project: Ambari

> Priority: Minor

> ssh-exkeys is setup to be executed as part of installation for the service.
> There is no install time dependencies for HAWQ components, so if hawq master
> install is triggered first, it will execute ssh keys with slaves but incase
> if hawq segment install is not invoked by ambari yet, gpadmin user will not
> be present and hawq master install may fail during it while exchanging keys.
> We need to put exchange keys during start of master service and not install.
