Collecting NiFi Registry database password
You need to migrate the NiFi Registry database password manually during the upgrade.
If you forget your database password, but you know your password which used to encrypt the NiFi
Registry password, you can decrypt the
nifi.registry.properties file properties
with the following command:
/usr/hdf/current/nifi-toolkit/bin/encrypt-config.sh -r /usr/hdf/current/nifi-registry/conf/nifi-registry.properties --decrypt --nifiRegistry -v -p <<password_used_for_encryption>>
The output of the command contains the database password.
