Apache Spark reassigned SPARK-33814:
------------------------------------
Assignee: Apache Spark (was: L. C. Hsieh)
> Provide preferred locations for stateful operations without reported state
> store locations
> ------------------------------------------------------------------------------------------
>
> Key: SPARK-33814
> URL: https://issues.apache.org/jira/browse/SPARK-33814
> Project: Spark
> Issue Type: Improvement
> Components: Structured Streaming
> Affects Versions: 3.2.0
> Reporter: L. C. Hsieh
> Assignee: Apache Spark
> Priority: Major
>
> Stateful operators in SS provides preferred locations on the previous batches
> if any. However, if there is no previous batch to follow, Spark possibly
> schedules stateful tasks in inefficient distribution. As stateful operations
> probably need to maintain large state stores, it is better we schedule
> stateful tasks across all executors.
