yihua opened a new pull request, #5353:
URL: https://github.com/apache/hudi/pull/5353
## What is the purpose of the pull request
This PR fixes the `NoClassDefFoundError` due to
`org.apache.hudi.schema.FilebasedSchemaProvider`. The class is not packaged to
the hudi-kafka-connect-bundle because of changes in flink modules (Right now,
Kafka Connect Sink for Hudi temporarily relies on schema provider classes in
Flink that do not use Spark context). The PR corrects the whitelist rule for
the flink module.
