> Project: Sentry
> Issue Type: Bug
> Components: Sentry
> Affects Versions: 2.2.0
> Reporter: Na Li

>
> In insecure mode, the current login user name is passed from Sentry to HMS
> server when sentry HMSFollower gets full snapshot from HMS.
> The user name should be "sentry" instead of current login user.
> The followiong code shows how current login user name is used when subject is
> null.
> In UserGroupInformation, if the context does not have subject, the
> getLoginUser() is used as user name
> @Public
> @Evolving
> public static UserGroupInformation getCurrentUser() throws IOException {
> AccessControlContext context = AccessController.getContext();
> Subject subject = Subject.getSubject(context);
> return subject != null && !subject.getPrincipals(User.class).isEmpty() ?
> new UserGroupInformation(subject) : getLoginUser();
> }
> This issue should not happen in production because secure mode is always
> used. Insecure mode is only used in test.
