Hi Feargal,
I am new with NiFi as well, but I was able to run it easily. I use the
downloadable version, just simply extracted it into my Downloads folder for
testing purposes.
When I start it from terminal I also get the 'JAVA_HOME is not set' error,
but it works like charm.
The nifi.sh file is in the bin library for me, and 'nifi' is not a
recognisable command in my terminal, so your installation from brew was
successful.
It seems that Java is not installed on your machine properly. I installed
it from packages I downloaded from Oracle, but someone with better Java
knowledge may help.
Here is the java version from my terminal:
~/D/*nifi-1.9.2 * java -version
3464ms Thu Jul 25 14:27:51 2019
java version "1.8.0_212"
Java(TM) SE Runtime Environment (build 1.8.0_212-b10)
Java HotSpot(TM) 64-Bit Server VM (build 25.212-b10, mixed mode)
Regards,
Adam
