Hello Leonard, Sivaprasanna, But my code was working fine with Flink v1.8. I also tried with a simple String DataStream, and got the same error. / StreamingFileSink .forRowFormat(new Path(path), new SimpleStringEncoder[String]()) .withRollingPolicy(DefaultRollingPolicy.builder().build()) .withBucketAssigner(new DateTimeBucketAssigner) .build()/ (screenshot below) <http://apache-flink-user-mailing-list-archive.2336050.n4.nabble.com/file/t1586/FlinkError.png>
It's weird. At first I thought it's something wrong with IntelliJ, but I got the same error when running mvn from commandline. -- Sent from: http://apache-flink-user-mailing-list-archive.2336050.n4.nabble.com/
