Hi Nifi Team, I've been attempting to install the Apache Nifi system for the better part of the day to no avail.
I installed it using brew with the following command on my Ubuntu virtual machine: brew install nifi After the installation, I ran nifi start, which appeared successful but didn't directly indicate so. Running nifi status gave me: 2018-06-17 16:39:45,534 INFO [main] org.apache.nifi.bootstrap.Command Apache NiFi is currently running, listening to Bootstrap on port 45631, PID=unknown Seems like it is running and should be accessible (although not sure why PID is unknown). However, http://domain:8080/nifi returns connection refused (I've confirmed port 8080 is accessible on my server). I did find this in the error log but have no idea what it means: java.util.ServiceConfigurationError: org.apache.nifi.authorization.UserGroupProvider: org.apache.nifi.authorization.FileUserGroupProvider Unable to get public no-arg constructor I also saw with certain installations you are supposed to verify the files using GPG or PGP. I did not take this step, but in the guide, it doesn't explicit state you do this when using brew. I must say the guide is quite vague. Could anyone shed some light on what I'm doing wrong or where my thinking is incorrect? Any help would be massively appreciated. Thank you, Evan
