> Open Add ResolveEventTimeWatermark to HiveSessionStateBuilder
> -------------------------------------------------------------

> Key: SPARK-56453
> URL: https://issues.apache.org/jira/browse/SPARK-56453
> Project: Spark
> Issue Type: Bug
> Components: Structured Streaming

> * {*}Add {{ResolveEventTimeWatermark}} to
> {{HiveSessionStateBuilder.extendedResolutionRules}}{*}: SPARK-53687
> introduced the {{UnresolvedEventTimeWatermark}} /
> {{ResolveEventTimeWatermark}} pattern for the SQL WATERMARK clause but only
> added the rule to {{{}BaseSessionStateBuilder{}}}.
> {{HiveSessionStateBuilder}} — used in all Databricks production environments
> (Hive catalog is the default) — was never updated. Without the rule,
> {{UnresolvedEventTimeWatermark}} (which has {{output = Nil}} per the
> {{UnresolvedNode}} contract) persists through analysis, blocking column
> resolution when WATERMARK is used with an alias in JOIN conditions.
> * *Add {{WatermarkColumnResolutionSuite}}* in both {{sql/core}}
> (BaseSessionStateBuilder) and {{sql/hive}} (HiveSessionStateBuilder) to cover
> STREAM + WATERMARK + alias column resolution through the production analyzer.
