Issue in nifi clustering

[#1]

i am trying to setup 3 different nifi instance on 3 node hadoop cluster.one on each machine, but getting below error -

i am getting this error on node2. All three nifi instances are up but they are not connected. i didn't see anything in NCM graph in connected node tag.

i have a feeling that i am missing some important property.

Although when i tried setting these 3 instance on same machine than it worked fine with same set of config.

Can anyone please help. Thanks in advance.

Thanks @mclark i was not setting these two properties.

1. # Site to Site properties
2. nifi.remote.input.socket.host=<--Set to the FQDN for the Node musty be resolvable by all other instances.
3. nifi.remote.input.socket.port=<--Set to unused port on Node.

Now my nifi cluster is up. Thanks for you help.
