ASF GitHub Bot updated SPARK-49070:
-----------------------------------
Labels: pull-request-available (was: )
> TransformWithStateExec.initialState is rewritten incorrectly to produce
> invalid query plan
> ------------------------------------------------------------------------------------------
>
> Key: SPARK-49070
> URL: https://issues.apache.org/jira/browse/SPARK-49070
> Project: Spark
> Issue Type: Bug
> Components: SQL, Structured Streaming
> Affects Versions: 4.0.0
> Reporter: L. C. Hsieh
> Priority: Major
> Labels: pull-request-available
>
> SPARK-47363 added the support for users to provide initial state for
> streaming query. Such query operators like `TransformWithStateExec` might
> have `hasInitialState` as false which means the initial state related
> parameters are not used. But when query planner applies rules on the query,
> it will still apply on the initial state query plan. When `hasInitialState`
> is false, some related parameters like `initialStateGroupingAttrs` are
> invalid and some rules will use these invalid parameters to transform the
> initial state query plan.
> For example, `EnsureRequirements` may apply invalid Sort and Exchange on the
> initial query plan. We encountered these invalid query plan in our extension
> rules.
