URL: https://github.com/apache/hudi/pull/19760
… branch in AvroKafkaSource
AvroKafkaSource#readFromCheckpoint re-configures KafkaAvroSchemaDeserializer
before every read: it stamps the schema provider's current schema into
hoodie.streamer.source.kafka.value.deserializer.schema, rotates group.id with a
schema hash so Spark does not reuse a cached KafkaConsumer whose deserializer
holds the old schema, and rebuilds KafkaOffsetGen. The branch regressed in
#10118 and #12111 and no test fetched through it.
Add TestAvroKafkaSource#testSchemaDeserializerRefreshesSchemaBetweenFetches:
produce Confluent-framed records under the simple fixture schema through the
in-JVM mock:// registry, fetch, evolve the SchemaTestProvider to the evolved
fixture, produce again, fetch again on the same source instance from the first
checkpoint, and assert the second batch carries the evolved schema and the new
field's value. The topic has one partition so both fetches share a consumer
cache key; dropping either the per-fetch re-configure or the group.id rotation
makes the second fetch decode with the stale reader schema.
Closes #19421
