Disowning a topic does not terminate subscriptions
---------------------------------------------------
Key: BOOKKEEPER-75
URL: https://issues.apache.org/jira/browse/BOOKKEEPER-75
Project: Bookkeeper
Issue Type: Bug
Reporter: Ivan Kelly
When a topic is dropped by the owning hub (e.g. due to a regularly scheduled
topic relinquishing), subscribers are not
notified. AbstractSubscriptionManager.lostTopic() simply removes the topic
from the local table. This only prevents
the system from being able to update subscription states for that topic (on
consume calls); subscribers remain
oblivious to this fact, as the failed attempts do not result in errors.
ActiveSubscriptionStates furthermore remain
present in the FIFODeliveryManager.
Proposed fix: notify subscribers with an error message so that they know to
resubscribe (with whoever the new topic
owner is).
