Hello!
The source csv file is:
123456TextValue1
654321TextValue2
where 123456 and TextValue1 are different values, separated by binary delimiter (\u0001)
Similar, 654321 and TextValue2 have non-visible at Web-UI binary delimiter (\u0001)
I use ConvertRecord for updating the delimiter from "\u0001" to ";"
RecordReader is CSVReader with the following properties:
- Schema Access Strategy: Use 'Schema Text' Property
- Schema Text: #{test_schema}
- Value Separator: \u0001
- Treat First Line as Header: false
- Ignore CSV Header Column Names: true
RecordWriter is CSVRecordSetWriter:
- Schema Access Strategy: Use 'Schema Text' Property
- Schema Text: #{test_schema}
- Value Separator: ;
- Include Header Line: true
test_schema is
{
"type": "record",
"name": "test_schema",
"fields": [
{
"name": "FIELD_1",
"type": ["int","null"],
"description": "FIELD_1"
},
{
"name": "FIELD_2",
"type": ["string","null"],
"description": "FIELD_2"
}
]
}
Expected output is:
FIELD_1;FIELD_2;
123456;TextValue1
654321;TextValue2
But I got the following error:
ERROR
ConvertRecord[id=01931001-0d7e-1e43-146d-1a380e6d43b7] Failed to process FlowFile[filename=7365b509-7100-4bc2-a070- 4cc8ce8377b9]; will route to failure: org.apache.nifi.processor.exception.ProcessException: Could not parse incoming data
