>                 URL: https://issues.apache.org/jira/browse/NIFI-87
>             Project: Apache NiFi
>          Issue Type: Improvement
>          Components: Core Framework

> Currently each node must have different values in its nifi.properties file for the hostname
> nifi.web.http.host
> nifi.web.https.host
> nifi.cluster.node.address
> In order to be scalable it must be the case that all nodes can have the exact same configuration.  This should be achieved by removing any reference to the hostname from the properties file and instead use the name of the Network Interface (or interfaces)
> nifi.web.http.interfaces=etho0,eth1,...
> Generally, in order to quickly scale up and down VMs will be used and it is considered acceptable to expect that all VM's should use the same NIC for comms.  This means we must fully understand exactly how these properties are used.  They are used in the JettyServer class as well as in clustering.
