Description

When we are validating AVRO schema against payload we just get one failed attribute information only. While in case of multiple attribute failure for a big schema it becomes difficult to correct the payload. Can it be corrected in the library so that we get all the information as in JSON we get.

Schema ::

{    "namespace": "tutorialspoint.com",    "type": "record",    "name": "emp",    "fields": [       \{"name": "name", "type": "string"}

,
      {"name": "id", "type": "int"},
      {"name": "salary", "type": "int"},
      {"name": "age", "type": "int"},
      {"name": "address", "type": "string"}
   ]
}

Test cases:
Test case 1.
Success Payload 
{"emp":{"name":"alex","id":2,"age":23,"salary":2000,"address":"xyz"}}

Test case 2.
Failure payload with 2 attributes wrong type(Address and salary)::
{"emp":{"name":"alex","id":2,"age":23,"salary":"Twenty thousand","address":123}}

Code implemented:
Schema schema = new Schema.Parser().parse(strSchema);
        try

{             JsonAvroConverter avroConverter = new JsonAvroConverter();             avroConverter.convertToGenericDataRecord(payload.getBytes(), schema);             LoggerUtility.writeLogger(SchemaValidator.class, LogLevel.INFO, "AVRO Schema successfully validated...");         }

catch (AvroRuntimeException e)

{             throw new SerializationException("AVRO does not match schema ", e);         }

Problem:

we want to get all the failures while validating the AVRO schema against payload. The avro library used in above code returns only one failure.
But in the Test case 2 in exception it just returns one failure not both.
