Summary: Fix migration of credential properties in AWS processors
Key: NIFI-12736
URL: https://issues.apache.org/jira/browse/NIFI-12736
Project: Apache NiFi
Issue Type: Bug
Reporter: Peter Turcsanyi
Assignee: Peter Turcsanyi
In AWS processors the processor level credential properties were removed in 2.0
in favour of AWS Credentials Provider Service. Migration code was added in
NIFI-12220.
The 1.x processors allowed to configure both the processor level Access Key ID
+ Secret Access Key and AWS Credentials Provider Service properties
({{{}customValidate(){}}} did not check it for some reason). In this case the
controller service took precedence.
The migration process first checks if Access Key ID + Secret Access Key are
configured and if they are, it creates a new controller service even if there
was another one already in use (and the new may have outdated migrated
credential values as the pre-existing service was used effectively in the flow).
Modify the migration logic to avoid controller service duplication and to use
the existing service.
Also modify the default credential to

as it was used if no properties were configured at all.
