DB Tsai updated SPARK-61097:
----------------------------
Fix Version/s: connect-rust-4.3.0
> Preserve a session streaming listener manager across property access
> --------------------------------------------------------------------
>
> Key: SPARK-61097
> URL: https://issues.apache.org/jira/browse/SPARK-61097
> Project: Spark
> Issue Type: Bug
> Components: Connect
> Affects Versions: connect-rust-4.3.0
> Reporter: DB Tsai
> Priority: Major
> Fix For: connect-rust-4.3.0
>
>
> Repeated access to SparkSession.streams constructs independent
> StreamingQueryManager instances and listener registries. For example,
> spark.streams.addListener(listener) followed by spark.streams.close() closes
> a different empty registry; removeListener also addresses a different
> registry. Official PySpark caches the session manager. Preserve listener
> state for one session while keeping new sessions isolated, and close the bus
> with the session. Add regressions for repeated property access, listener
> removal and cleanup.
> Observed by source inspection of public apache/spark-connect-rust master
> 83d74462ec41012993176cf3af99017576688eb8. Runtime regression tests will
> accompany the fix.
