Andre Araujo commented on NIFI-7043:
------------------------------------
The [^UpdateRecord.xml] template has a sample flow to demonstrate the problem.
It works fine on 1.9.
The schema stored on the registry is the one below:
{code:json}
{
"type": "record",
"name": "TestIP",
"namespace": "com.cloudera.example",
"doc": "This is a test",
"fields": [
{
"name": "id",
"doc": "Sensor identification number.",
"type": "int"
},
{
"name": "new",
"doc": "Sensor identification number.",
"type": "int",
"default": 0
},
{
"name": "response",
"doc": "response record",
"type": {
"type": "record",
"name": "RestResponse",
"namespace": "com.cloudera.example",
"doc": "This is a response",
"fields": [
{
"name": "now",
"doc": "bla",
"type": "string"
}
]
}
}
]
}

> URL: https://issues.apache.org/jira/browse/NIFI-7043
> Project: Apache NiFi
> Issue Type: Bug
> Components: Core Framework
> Affects Versions: 1.10.0
> Reporter: Andre Araujo
> Priority: Major
> Attachments: UpdateRecord.xml
>
>
> When using an UpdateRecord processor with JsonRecordSetWriter, with Schema
> Access Strategy set to Inherit Record Schema, I get the exception shown below.
> This is a regression. The same flow works on NiFi 1.9.x without problems.
> As a workaround, if I change the record writer's to get the schema directly
> from Schema Registry, instead of inheriting it, the flow works fine.
