----------------------------------
Summary: ConvertAvroSchema should not require InputSchema
Key: NIFI-3457
URL: https://issues.apache.org/jira/browse/NIFI-3457
Project: Apache NiFi
Issue Type: Improvement
Components: Extensions
Reporter: Matt Burgess
Currently, the ConvertAvroSchema processor requires both an Input and Output
Schema in order to perform a conversion. The Input Schema should only be
necessary if the Avro file(s) coming in are "raw" (aka schema-less). Otherwise
the schema should be in the file and if the Input Schema property is left
blank, the processor should attempt to retrieve the schema from the incoming
Avro file. If the incoming file is schema-less and the property is left blank,
then an error bulletin can be issued, saying that no schema was found or
supplied.
The proposed changes are these:
1) Make the Input Schema property .required(false)
2) If the Input Schema property is empty, attempt to retrieve the schema from
the incoming flow file. If no schema exists, issue an error
3) Update the processor documentation to reflect this additional behavior.
