------------------------------------

             Summary: Parameters update not taken into account in controller services
                 Key: NIFI-7242
                 URL: https://issues.apache.org/jira/browse/NIFI-7242
             Project: Apache NiFi
          Issue Type: Bug
          Components: Core Framework
            Reporter: Pierre Villard
             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.
