Hello,
I'm having trouble running the java/GettingStarted project. When I run BasicStreamingJob.main(), I get the error java.lang.NoClassDefFoundError: org/apache/flink/streaming/api/functions/source/SourceFunction. See the java version check and full error below.
What can I do to fix this error?

Process finished with exit code 1Hi there,
I was reading through the https://github.com/aws-samples/amazon-managed-service-for-apache-flink-examples/tree/main/java/S3ParquetSink/src/main/resources, and found that there is flink-conf.yaml and core-site.xml and trying to specify s3.endpoint in the code.
Does MSF now support CX to specify the flink configuration file directly?
Remove TableAPI dependencies from https://github.com/aws-samples/amazon-kinesis-data-analytics-examples/blob/master/KafkaConnectors/pom.xml
There has been iceberg example,can you give stream sink hudi example?
On both GettingStarted and GettingStartedTable, add support to load configuration from runtime properties or command line
