-----------------------------------------

             Summary: JsonRecordAvroSchemaToAvroConverter does not reject unrecognized Enum symbols
                 Key: GOBBLIN-987
                 URL: https://issues.apache.org/jira/browse/GOBBLIN-987
             Project: Apache Gobblin
          Issue Type: Bug
            Reporter: Ahmed Abdul Hamid
         Attachments: invalid-enum-unit-test.patch

Here is a failing unit test that demonstrates the issue we encounter when we attempt to encode the records produced by {{JsonRecordAvroSchemaToAvroConverter}} with unrecognized Enum symbols: [^invalid-enum-unit-test.patch]

Here's how to apply the patch and run the test:
{code:bash}
$ git apply invalid-enum-unit-test.patch$ 
$ ./gradlew :gobblin-core:test --tests *testEnumConversion*  {code}
Here's the output:
{code:java}
java.lang.NullPointerException: null of string in field fieldToIgnore of org.apache.gobblin.test.TestRecord
      at org.apache.avro.generic.GenericDatumWriter.npe(GenericDatumWriter.java:132)
      at org.apache.avro.generic.GenericDatumWriter.writeWithoutConversion(GenericDatumWriter.java:126)
      at org.apache.avro.generic.GenericDatumWriter.write(GenericDatumWriter.java:73)
      at org.apache.avro.generic.GenericDatumWriter.write(GenericDatumWriter.java:60)
      at org.apache.gobblin.converter.avro.JsonRecordAvroSchemaToAvroConverterTest.testEnumConversion(JsonRecordAvroSchemaToAvroConverterTest.java:82) {code}
The root cause of the issue that {{JsonRecordAvroSchemaToAvroConverter}} allows unrecognized Enum symbols not declared in the specified Avro schema.
