NIFI-5284: Added JSON_TYPE support to RunMongoAggregation
----
> RunMongoAggregation uses ObjectIdSerializer & SimpleDateFormat
> --------------------------------------------------------------
>
> Key: NIFI-5284
> URL: https://issues.apache.org/jira/browse/NIFI-5284
> Project: Apache NiFi
> Issue Type: Improvement
> Components: Extensions
> Affects Versions: 1.6.0
> Reporter: Zambonilli
> Assignee: Sivaprasanna Sethuraman
> Priority: Minor
>
> The RunMongoAggregation processor uses Jackson to serialize the document to
> JSON. However, the default serialization for Jackson on Mongo ObjectId and
> dates leaves a lot to be desired. The ObjectId's are serialized into the
> decimal representation of each component of the ObjectId instead of the hex
> string of the full byte array. Mongo dates are being serialized as unix time
> as opposed to ISO8601 zulu string.
> It looks like the GetMongo processor has set the correct serializer flags on
> Jackson to fix this. The fix for GetMongo is here.
