Alexander Kolbasov commented on SENTRY-1693:
--------------------------------------------

Note that this event was already processed by Hive and we can't communicate 
error back to Hive. If we throw an exception and fail to process this 
notification, the result will be a completely dysfunctional Hive which is bad. 
So my take is that Sentry should not refuse any notifications.

> Adding a view with create a notification with empty path. This is not handled 
> properly in HMS follower

> When a view is created in Hive, notification log generated would have empty 
> path. HMS Follower throws an exception on such notifications. HMS Follower 
> doesn't update the notification-id and will continue getting same 
> notification again and again. As a result HMS will not be able to process 
> subsequent notifications.
