Ok, so if i run the command as root it works:

/var/lib/ambari-agent/cache/common-services/NIFI/1.0.0/package/files/nifi-toolkit-1.1.0.2.1.1.0-2/bin/encrypt-config.sh -v -b /usr/hdf/current/nifi/conf/bootstrap.conf -n /usr/hdf/current/nifi/conf/nifi.properties -f /var/lib/nifi/conf/flow.xml.gz -s 'mypassword!' -p 'mypassword!'

Ok here is the solution:

I modified the /var/lib/ambari-agent/cache/common-services/NIFI/1.0.0/package/files/nifi-toolkit-1.1.0.2.1.1.0-2/bin/encrypt-config.sh

Added the line:

echo "The place it is looking is: ${CLASSPATH}"

The place it is looking is: /var/lib/ambari-agent/cache/common-services/NIFI/1.0.0/package/files/nifi-toolkit-1.1.0.2.1.1.0-2/lib/*

Now I updated the permissions on the lib folder and contents, everything works now!
