apache - Recover NiFi project

Question

My Desktop crashed, and I recovered it.

However, my NiFi project disappeared. When I go to http://192.168.1.36:8080/nifi/ I see only a blank canvas. Is there a way to recure?

NiFi is installed on /opt/nifi-1.10.0/

Answer 1

you can recover it if you have the flow.xml.gz present in archive directory . You can open nifi.properties and search for the property- nifi.flow.configuration.file. This property defined the flow file that will be loaded while starting the nifi. Also, nifi takes the backup of flow.xml in a location which is defined by the propety nifi.flow.configuration.archive.dir.

You can replace the flow.xml.gz with the archive one and reboot the nifi. The older flows will be recovered.
