-----------------------------------------------------------
[~aldrin] [~alopresto] thanks for your help.
You were correct in that jenv versions were different between my account using
sudo and root.
Interestingly there is no "sudo Jenv versions" atleast on my machine.
'sudo jenv versions
sudo: jenv: command not found'
But when I opened the terminal as root 'jenv versions' showed a different
version
as root, opening a Jenv shell with java_home set to java8 and then launching
nifi it picked up the correct java version.

> Key: NIFI-6584
> URL: https://issues.apache.org/jira/browse/NIFI-6584
> Project: Apache NiFi
> Issue Type: Improvement
> Environment: Distributor ID: Ubuntu
> Description: Ubuntu 18.04.3 LTS
> Release: 18.04
> Codename: bionic
> https://github.com/jenv/jenv
> Reporter: Ben Stuart
> Priority: Major
> Fix For: 1.9.1
>
>
> I've been notified NiFi dosen't support java11 yet and suspect that is the
> reason Nifi won't lunch.
> I am trying to get around this by using jenv.
> Having a look at the screenshot below you can see when I launch NiFi it
> believes the java home is still set to Java11.
> I suspected it's realted to this: [https://github.com/jenv/jenv/issues/224]
> in summary, I suspect NiFi is pointing to a full static path to the java file
> opposed to referencing $JAVA_HOME
> I'm hoping if this is the case, it can be improved to recognize the change
> better.
