Hi, Averell I found you’re using scala so I reproduced your case local in Scala 2.11.12 with Flink 1.10.0 and it works too. From your picture it’s wired that line`.withBucketAssigner(new DateTimeBucketAssigner)` hint is `Any`, it should be `RowFormatBuilder` otherwise you can not call `#build` function from an `Any` object. You can debug this line and to see what happened.
