> Potential bug with Fetch Parquet
> --------------------------------
>
> Key: NIFI-5316
> URL: https://issues.apache.org/jira/browse/NIFI-5316
> Project: Apache NiFi
> Issue Type: Bug
> Affects Versions: 1.6.0
> Reporter: Robert Bruno
> Priority: Major
>
> I have used PutParquet to create Parquet files from Nifi Records. In trying
> to convert the parquet back to json by using FetchParquet, I keep getting
> errors on what seems like any array field. I have had successes on data that
> contained no arrays.
> The error in the log is cannont convert a value [xxx, yyy] where xxx and yyy
> are random strings of type class java.util.ArrayList because no compatible
> type exist in the UNION of field z.
> I am also see the same error when the value is [] (empty array) as well.
> I have been successful gong from json to avro and avro to json with the same
> schema registry values.
> I am defining array fields as follows:
> "type" : [
> "null",
> {
> "type" : "array",
> "items" : "string"
> }
> ],
> "default": null
> }
