-----------------------------------
Labels: pull-request-available (was: )
> Preserve root causes for RTM async operation failures
> -----------------------------------------------------
>
> Key: SPARK-59844
> URL: https://issues.apache.org/jira/browse/SPARK-59844
> Project: Spark
> Issue Type: Improvement
> Components: Structured Streaming
> Affects Versions: 4.4.0
> Reporter: Boyang Jerry Peng
> Priority: Major
> Labels: pull-request-available
>
> Async progress tracking writes checkpoint offset and commit logs on a
> background thread. In Real-Time Mode, a failure in that thread interrupts the
> query execution thread.
> ErrorNotifier retains the first asynchronous error it observes. If it had
> already retained an earlier, non-interrupting error, the query could report
> that earlier error instead of the
> checkpoint-log failure that caused the interruption. A race with the
> foreground error check could also make the reported exception shape depend on
> timing.
> Additionally, asynchronous futures can introduce nested CompletionException
> or ExecutionException wrappers that obscure an already-categorized Spark
> error. Attaching related exceptions
> as suppressed errors could create cyclic or overlapping throwable graphs,
> producing [CIRCULAR REFERENCE] in rendered stack traces.
> This change makes the primary cause deterministic and exposes the actionable
> checkpoint-storage exception while retaining independent diagnostic context.
