Hi Andy, I have tested it with NIFI 1.8.0 I get the a diferent error. Unable to get the state for the specified component afc9148c-0167-1000-ffff-ffffa97bf4b6: java.io.IOException: Failed to obtain value from ZooKeeper for component with ID afc9148c-0167-1000-ffff-ffffa97bf4b6 with exception code CONNECTIONLOSS
Thanks, Milan Das On 11/8/18, 6:41 PM, "Andy LoPresto" <alopre...@apache.org> wrote: There was an issue with malformed replicated requests causing a timeout [1] in previous versions, and this was resolved in 1.8.0. Could you try against 1.8.0? This issue had nothing to do with ZK though, so if the only difference between working/failing is whether ZK is secured, I think the problem is there. Are you sure that your ZK configs are correct?
