[jira] [Updated] (NIFI-5690) JsonRecordSetWriter: coercion RECORD/MAP/CHOICE/ARRAY to json string

     [ https://issues.apache.org/jira/browse/NIFI-5690?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

David Voit updated NIFI-5690:
-----------------------------
    Description: 
Hi All,

Having the following json:

{"bla": \{"fasel": "bla"}}

with the following AVRO reading schema:

{
 "type" : "record",
 "name" : "BlaRecord",
 "fields" : [ {
 "name" : "bla",
 "type" : {
 "type" : "record",
 "name" : "faselRecord",
 "fields" : [

{ "name" : "fasel", "type" : "string" }

]
 }
 } ]
 }

Using a ConvertRecord with JsonRecordSetWriter and the following output schema:

{
 "type" : "record",
 "name" : "BlaRecord",
 "fields" : [

{ "name" : "bla", "type" : "string" }

]
 }

 

a output like the following would be nice/expected:

{"bla": "\{\"fasel\": \"bla\"}"}

But we are getting:

[{"bla":"MapRecord[

{fasel=bla}

]"}]

Which seems completly useless this way. We needs this functionality to save a record in a hbase column as a json string.

 

Regards and Thanks,

David
