Review comment:
Given more exception information, e.g. : when choose
`ByteArrayDeserializer `?

> Add support ByteArrayDeserializer in AvroKafkaSource
> ----------------------------------------------------
>
> Key: HUDI-2320
> URL: https://issues.apache.org/jira/browse/HUDI-2320
> Project: Apache Hudi
> Issue Type: Improvement
> Components: DeltaStreamer
> Reporter: 董可伦
> Assignee: 董可伦
> Priority: Major
> Labels: pull-request-available
> Fix For: 0.10.0
>
>
> When the 'value.serializer' of Kafka Avro Producer is
> 'org.apache.kafka.common.serialization.ByteArraySerializer',Use the following
> configuration
> {code:java}
> --source-class org.apache.hudi.utilities.sources.AvroKafkaSource \
> --schemaprovider-class
> org.apache.hudi.utilities.schema.JdbcbasedSchemaProvider \
> --hoodie-conf
> "hoodie.deltastreamer.source.kafka.value.deserializer.class=org.apache.kafka.common.serialization.ByteArrayDeserializer"
> {code}
> For now,It will throw an exception::
> {code:java}
> java.lang.ClassCastException: [B cannot be cast to
> org.apache.avro.generic.GenericRecord{code}
> After support ByteArrayDeserializer,Use the configuration above，It works
> properly.And there is no need to provide 'schema.registry.url',For example,
> we can use the JdbcbasedSchemaProvider to get the sourceSchema
