Trouble sending files
Howdy
I'm trying to send files between 2 nifi instances on different computers.
I read a bunch of files, they are sitting in the Q. I wire them to an
output port. On the other machine I have an input port of the same name
which is happily waiting for the files. Nothing happens.
I have on both machines set:
nifi.remote.input.socket.port=1234
nifi.remote.input.secure=false
What else do I have to do to let Nifi know about another instance/instances
and cause them to communicate.
I don't see any errors in the logs.
thank you,
Patrick Jones

Hi Patrick.
There are generally two approaches to sending data between nifi instances...
- The sending instance brings data to a remote process group which is
pointing at the receiving nifi, the receiving nifi has an input port to
receive the data
- The sending instance brings data to an output port, and the receiving
instance has a remote process group pointing at the output port of the
sending instance
Basically push vs. pull. Either approach will work, but the advantage of
the first approach (pushing) is that the sending nifi is deciding where to
send its data, as opposed to data waiting at an output port for anyone to
consume.
You can add a remote process group from the top menu, and you will be
prompted to enter the url location of the remote nifi. Let us know if you
have any questions getting this to work.
