Mark Payne commented on NIFI-868:
---------------------------------
Chin,
I'd like to echo Joe's comments here: this is very nicely done and put
together. I tested it out and all appears to work as expected.
This property will only affect site-to-site communication when the NiFi
instance is not clustered. I have created a new ticket, NIFI-872 to take
advantage of this property when in a clustered environment also. This is a bit
more involved, though, as it requires notifying the NCM of the configured
hostname.
This is certainly a great improvement as-is, though! Many thanks for taking the
time to contribute this back. I have merged the pull request into master, so it
will go out soon, in version 0.3.0.
Thanks

> Configure advertised host name of Remote Process Group Input Port

> Project: Apache NiFi
> Issue Type: Improvement
> Components: Core Framework

> Environment: Linux
> Reporter: Chin Huang

>
> The host given out to clients to connect to a Remote Process Group Input Port
> is the host where the NiFi instance runs. However, sometimes the binding host
> is different from the host that clients connect to. For example, when a NiFi
> instance runs inside a Docker container, a client on a separate machine must
> connect to the Docker host which forwards the connection to the container.
> Kafka addresses this situation by allowing a broker to configure the host
> name given out to producers, consumers, and other brokers to connect to.
> Implement something similar in NiFi. Add a configuration property to specify
> the host name to give out to clients to connect to a Remote Process Group
> Input Port. If the property is not configured, then give out the name of host
> running the NiFi instance.
