Description

Given an Avro Schema that has a default array defined, it is not possible to be converted to a Nifi Record Schema.

To reproduce the bug, try to convert the following Avro schema to Record Schema:

{
    "type": "record",
    "name": "Foo1",
    "namespace": "foo.namespace",
    "fields": [
        {
            "name": "listOfInt",
            "type": {
                "type": "array",
                "items": "int"
            },
            "doc": "array of ints",
            "default": 0
        }
    ]
}

 
Using org.apache.nifi.avro.AvroTypeUtil class. Attached a maven project to reproduce the issue and also the fix.

• To reproduce the bug, run "mvn clean test"
• To test the fix, run "mvn clean test -Ppatch".
