Installing Custom Processors
This section describes the original process for installing custom processors that requires a restart to NiFi. To use the Autoloading feature, see the below Autoloading Custom Processors section.
Firstly, we will configure a directory for the custom processors. See Available Configuration Options for more about these configuration options.
Ensure that this directory exists and has appropriate permissions for the nifi user and group.
Now, we must place our custom processor nar in the configured directory. The configured directory is relative to the NiFi Home directory; for example, let us say that our NiFi Home Dir is
/var/lib/nifi, we would place our custom processor nar in
Ensure that the file has appropriate permissions for the nifi user and group.
Restart NiFi and the custom processor should now be available when adding a new Processor to your flow.
