> Batch queries with 'Dataset/DataFrame.withWatermark()` does not execute
> -----------------------------------------------------------------------
>
> Key: SPARK-20373
> URL: https://issues.apache.org/jira/browse/SPARK-20373
> Project: Spark
> Issue Type: Bug
> Components: Structured Streaming
> Affects Versions: 2.1.0, 2.2.0
> Reporter: Tathagata Das
> Priority: Minor
>
> Any Dataset/DataFrame batch query with the operation `withWatermark` does not
> execute because the batch planner does not have any rule to explicitly handle
> the EventTimeWatermark logical plan. The right solution is to simply remove
> the plan node, as the watermark should not affect any batch query in any way.
> {code}

> eventsDF = spark.createDataFrame([("2016-03-11 09:00:07", "dev1",
> 123)]).toDF("eventTime", "deviceId",
> "signal").select(col("eventTime").cast("timestamp").alias("eventTime"),
> "deviceId", "signal")
> windowedCountsDF = \
> eventsDF \
> .withWatermark("eventTime", "10 minutes") \
> .groupBy(
> "deviceId",
> window("eventTime", "5 minutes")) \
> .count()
> windowedCountsDF.collect()

> This throws as an error
