@regie canada The extractText processor creates FlowFile attributes from the extracted text. NiFi has an AttributesToJSON processor you can use to generate JSON form these created attributes. For new questions, please open a new question. It makes it easier for community users to search for answers. Thanks, Matt ... View more

@Muhammad Umar When NiFi starts and has not been configured with a specific hostname or IP in the (nifi.web.http.host=) in the nifi.properties file, it looks to bind to the IP address registered to every NIC card present on the host system. If you try to specify a hostname or IP that does not resolve or match the IP registered to any of your NIC cards, NiFi will fail to start. NiFi can not bind to a port that belongs to an IP it does not own. You can run the "ifconfig" command on the host running NiFi to see all NICs and the IP registered to them. You should see the 172.17.x.x address and not the 192.168.x.x address shown. It definitely sounds like there is some network address translation going on here. The fact that you can reach NiFi over http://192.68.x.x:8078// confirms this. It is simply routing all traffic from the 192.169.x.x address to the internal 172.17.x.x address. We confirmed already your browser cannot resolve a path directly to 172.17.x.x, because if you could, NiFi's UI would have opened. NiFi is in fact bound to 172.17.x.x and not 192.168.x.x. NiFi cannot control how traffic is being routed to this endpoint by the network. Thanks, Matt ... View more

In my understanding, everything is based anyhow on "processGroup". and there is a "root" process group that is shared among all the users. It would be nice to allow the creation of multiple "root" process group and define for a user or a group of user what is the root "processGroup". Of course, super users or users belonging to different groups, should have the possibilty to see the list of root "processGroup" they can access and enter it. what do you think? for real multi-tenancy this would be quite interesting. ...

Based on what you provided above it looks like you installed via the nifi tar.gz file. By default NiFi runs unsecure on port 8080. So yes, you want to change that port to some unused port on your server. Thanks, Matt ... View more
