HiveSimpleConnectionFactory is used by HMSFollower to get notifications from
HMS server. It is not used for any other purposes in Sentry.
If we following your suggestion, the user will be the login user, it could be
"root" for one run, and "jenkins" for another run. How to make sure fetching
notification from sentry works in your suggested approach?
That is why I have this solution here. Make sure the user is "sentry" in
insecured mode, and add "sentry" as services in HMS server.
