Mark Payne commented on NIFI-4901:
----------------------------------
[~gardellajuanpablo] I believe the behavior that you describe above in this
Jira is the expected behavior. The schema that you provided indicates that
there is a single field named "isSwap" and that its type is either boolean or
null. So it would match something like:
{code:java}
{
"isSwap": true
}{code}
In the sample JSON that you provided, the "isSwap" field is itself a record
with a field named "boolean". So a matching schema would look like this:
{code:java}
{
"type":"record",
"name":"foo",
"fields":[
{
"name":"isSwap",
"type": {
"type": "record",
"name": "isSwapRecord",
"fields": [
{
"name": "boolean",
"type": [ "boolean", "null" ]
}
]
}
}
]
}{code}
> Json to Avro using Record framework does not support union types with boolean

> Key: NIFI-4901
> URL: https://issues.apache.org/jira/browse/NIFI-4901
> Project: Apache NiFi
> Issue Type: Bug
> Components: Core Framework
> Affects Versions: 1.5.0
> Environment: ALL
> Reporter: Gardella Juan Pablo
> Priority: Major
> Attachments: optiona-boolean.zip
>
>
> Given the following valid Avro Schema:
> {code}
> {
> "type":"record",
> "name":"foo",
> "fields":[
> {
> "name":"isSwap",
> "type":[
> "boolean",
> "null"
> ]
> }
> ]
> }
> {code}
> And the following JSON:
> {code}
> {
> "isSwap": {
> "boolean": true
> }
> }
> {code}
> When it is trying to be converted to Avro using ConvertRecord fails with:
> {{org.apache.nifi.serialization.MalformedRecordException: Successfully parsed
> a JSON object from input but failed to convert into a Record object with the
> given schema}}
> Attached a repository to reproduce the issue and also included the fix:
> * Run {{mvn clean test}} to reproduce the issue.
> * Run {{mvn clean test -Ppatch}} to test the fix.
