The specific processors you mention were never part of any distribution of Apache NiFi.

 

1. JSONToAttributes:
Typically when extracting json elements in to FlowFile Attrinutes you would use the EvaluateJsonPath processor.  There is an "AttributesToJson" processor, is that maybe what you mean?

2. ConvertJSONToAvro
NiFi ships with a ConvertAvroToJson processor, is that perhaps what you mean? If you trying to convert from one content format to another, the preferred processor to use would be "convertRecord".  In this processor's configuration you would select a Record Reader which reads the current format of the inbound FlowFile's content (JsonPathReader or JsonTreeReader in this case) and you then select a Record Writer (AvroRecordSetWriter in this case) which writes the content for the outbound FlowFile.

 

If the processor types you mentioned did exist for you, then they were added via a custom nar to your previous NiFi installations.

 

Hope this helps,

Matt

It seems more complicated than using JSONToAttributes or ConvertJSONToAvro processor (NiFi version lower 1.7 are supported)

@thuylevn 

As i mentioned, NiFi has never been released with either a "JSONToAttributes' or "ConvertJSONToAvro" processor.  All I can do is suggest existing processors which can hopefully accomplish what your use case requires.  The other option is for you to build your own custom processor implementations and add them to your NiFi.

 

Hope this helps.  

Thank you,

Matt
