I have the following schema in my test flow:
`{
"type": "record",
"name": "A","fields": [
{"name": "a", "type": "string"},
{"name": "c", "type": [ "null", {"type" : "map","values" : "string"} ] }
]
}`
When I debug through the processor to AvroTypeUtil, I get a MapRecord as
the type of "value", not Map. If it could be either, we could just check for
either?
