URL: https://github.com/apache/hudi/pull/3502
## What is the purpose of the pull request
Add support ByteArrayDeserializer in AvroKafkaSource
## Verify this pull request
When the 'value.serializer' of Kafka Avro Producer is
'org.apache.kafka.common.serialization.ByteArraySerializer',Use the following
configuration
--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"
For now,It will throw an exception:
java.lang.ClassCastException: [B cannot be cast to
org.apache.avro.generic.GenericRecord
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
