----------------------------------
Resolution: Not A Problem
> Fast fail with explicit err msg when calling withWatermark on non-streaming
> dataset
> -----------------------------------------------------------------------------------
>
> Key: SPARK-36954
> URL: https://issues.apache.org/jira/browse/SPARK-36954
> Project: Spark
> Issue Type: Improvement
> Components: SQL, Structured Streaming
> Affects Versions: 3.1.2
> Reporter: huangtengfei
> Priority: Minor
>
> [Dataset.withWatermark|https://github.com/apache/spark/blob/v3.2.0-rc7/sql/core/src/main/scala/org/apache/spark/sql/Dataset.scala#L740]
> is a function specific for SS.
> Now it could be triggered on a batch dataset, and add a specific rule to
> eliminate in analyze phase. User can call this API and nothing happens, it
> may be a little bit confused.
> If the usage is not as expected, maybe we can just fast fail it with explicit
> message, and also we do not have to keep on extra rule to do this.
