Ricky Saltzer commented on NIFI-1598:
-------------------------------------
[~joewitt] - do you know of any way to do this without accessing the web API?
I've made a crude version, but it requires using the NiFi web API. I'm not a
fan of using the web API since it requires you to make assumptions on which
port the web API port the master is listening on.
Thanks!
