> Key: NIFI-7242
> URL: https://issues.apache.org/jira/browse/NIFI-7242
> Project: Apache NiFi
> Issue Type: Bug
> Components: Core Framework
> Reporter: Pierre Villard
> Assignee: Mark Payne
> Priority: Blocker
> Fix For: 1.12.0, 1.11.4

> Attachments: parametersIssue.xml

> There is a bug with the parameters when used in Controller Services:
> * when updating a parameter that is referenced in a controller service (in
> this case avro schema registry), changing the value of the parameter does not
> seem to trigger the restart of the controller service
> * even if I do restart the components manually, the old value of the
> parameter is still used... NiFi restart is the only way to get the new value
> applied
> With the supplied template, create a Parameter Context with schema =
> {code:java}
> {
> "type" : "record",
> "name" : "myData",
> "namespace" : "myLine",
> "fields" : [
> {
> "name" : "myField1",
> "type" : "string"
> }
> ]
> }
> {code}
> The AvroSchemaRegistry contains the schema with:
> schema => #\{schema}
> Get everything running: output data has only one column. Then update the
> Parameter Context to have schema =
> {code:java}
> {
> "type" : "record",
> "name" : "myData",
> "namespace" : "myLine",
> "fields" : [
> {
> "name" : "myField1",
> "type" : "string"
> }, {
> "name" : "myField2",
> "type" : "string"
> }
> ]
> }
> {code}
> Output data has still one column only when it should have two with the new
> schema.
