merlimat opened a new pull request #8273:
URL: https://github.com/apache/pulsar/pull/8273
### Motivation
When the broker is starting up, it might start getting lookup requests
before all the components of the service are fully initialized. In this
particular case a lookup will fail on NPE because the leader election service
is not ready yet (it gets instantiated after the broker service).
This NPE causes a series of rippling effects:
* The future for the request hitting NPE are not completed
* They stay stale in the `findingBundlesNotAuthoritative` cache map forever
* All other lookup requests are piggy-backing on the first futures (but
these will not complete)
* We reach the max number of pending lookup requests, after which the
broker rejects new lookup
