Nifi 1.5 Cluster

[Samuel Miller <sa...@usermind.com>]

Does anyone know how to cluster NiFi 1.5.0? I want to use
dataflow.mydomain.com but... I get this error when I try to hit the
loadbalancer that reads:
 "The request contained an invalid host header [dataflow.mydomain.com] in
the request [/nifi/]. Check for request manipulation or third-party
intercept."

According to one post that I read, the problem was that the value of
nifi.web.http.host had to match the value of the url.

If that's true, I don't understand how a cluster would be possible.

Thanks!

You need to give the host where the NiFi instance is running in
nifi.web.http.host. For ex, say you are clustering NiFi in three nodes:
10.8.18.41,  10.8.18.42, 10.8.18.43. The nifi.properties in the respective
nodes should have the node's hostname or IP for nifi.web.http.host. You
need to configure the loadbalancer saying the there are three nodes and
mention their IP and host. NiFi instance shouldn't be configured with the
VIP. And when you hit the VIP i.e. dataflow.mydomain.com, it will bring any
of the NiFi instance's UI. The idea of load-balancing is to actually
balance the load/traffic sent to the NiFi instances.
