Hi.
I'm a bit confused: When launching my flink streaming application on EMR release 5.24 (which have flink 1.8 version) that write Kafka messages to s3 parquet files i'm getting the exception below, but when i'm installing flink 1.8 on EMR custom wise it works. What could be the difference behavior? Thanks, Yitzchak.
