Thanks for the explanation. I found that [docs says
so](https://nifi.apache.org/docs/nifi-docs/html/administration-guide.html#clustering).
I have read `nifi.remote.input.socket.host` description before, and
wondered what's the reason of these difference:
```
By default, it is the value from InetAddress.getLocalHost().getHostName().
On UNIX-like operating systems, this is typically the output from the hostname
command.
```
I understand that as to keep how it was done in 0.x.
