poorbarcode opened a new pull request, #23011:
URL: https://github.com/apache/pulsar/pull/23011
### Motivation
**background**
- Once a broker's(we call it `broker-1`) ZK session has expired, the topics
it owns will be assigned to other brokers
- And the `broker-1` will get a `BadVersionException`, then the topics will
be marked `fenced`.
- Other brokers will load up the topics
- At this moment there is more than one broker who owns the same topic.
- The clients who connected to `broker-1` will get a fenced error.
Issue: the topics on `broker-1` will not be unloaded until it restarts, so
we'd better change the default behavior of the action when ZK session expires
to `shutdown`, which will solve the issue automatically. We can set it back to
`reconnect` after we improve the behavior to unload the topic automatically in
the future.
### Modifications
Change default behavior when ZK session expired to `shutdown`.
