Nathan Gough commented on NIFI-9294:
------------------------------------
As Wiktor states, you absolutely should never run NiFi as root. When you’re
using sudo ./bin/NiFi.sh, this creates a new shell environment which probably
does not have the same environment variables set as your ‘grivine’ user. So,
you will not have JAVA_HOME set when running with sudo. If you had included -E,
it would have preserved environment variables.
Basically, don't run NiFi as root user or with sudo, and you should not have
this issue.
I'll close this ticket as it's an individual issue with machine configuration
and not a NiFi bug. If you're still having the issue, feel free to ask for
assistance on our Apache NiFi slack channel or the mail list
us...@nifi.apache.org.
