Review comment:
You need to check if the `GenericSchema` is AVRO or not before casting it to
`GenericAvroSchema`.
```
checkArgument(genericSchema.getSchemaInfo().getSchemaType() ==
SchemaType.AVRO,
"The field is expected to be using AVRO schema but " +
genericSchema.getSchemaInfo().getSchemaType() + " schema is found");
GenericAvroSchema genericAvroSchema = (GenericAvroSchema) genericSchema;
```
