Looks like Hazelcast will enable the Multicast Joinger[1] if autodetect is
enabled. And it is by default [2]. This causes Multicast to be enabled when
this is run locally
{code:java}
2024-02-20 19:14:41,547 INFO [Timer-Driven Process Thread-6]
com.hazelcast.instance.impl.Node [192.168.56.1]:5701 [nifi] [5.3.5] Using
Multicast discovery {code}
By disabling the auto detect this does not happen
[https://github.com/apache/nifi/pull/8440]
I get the following in the logs which I believe is expected.
{code:java}
2024-02-20 19:23:15,870 WARN [Timer-Driven Process Thread-2]
com.hazelcast.instance.impl.Node [192.168.56.1]:5701 [nifi] [5.3.5] No join
method is enabled! Starting standalone. {code}
This should also address the issue above since it appears to be hitting a
usecase where the DiscoveryJoiner is enabled. This should also be suppressed
by autodetect being disabled [3]. This appears to happen in both 1.x and 2.x
