I want to add 3 extension to nifi (nifi-encryptMD5-nar-1.0.nar-unpacked,nifi-getOperator-nar-1.0-SNAPSHOT.nar-unpacked,nifi-splitAttributeValue-nar-1.0.nar-unpacked)
I added the extensions folder in the directory /opt/nifi/nifi-1.9.2/work/nar/extensions/
then when I restart the nifi service, nifi turns off and does not turn on, when I force the start with the user nifi, nifi turns on but the extentions have been deleted from the directory /opt/nifi/nifi-1.9.2/work/nar/extensions/
you have to put *.nar packages into nifi/lib directory.
nifi will extract it automatically on startup into nifi/work folder.
