Matthew Tieman resolved SPARK-43819.
------------------------------------
Resolution: Not A Problem
> Barrier Executor Stage Not Retried on Task Failure
> --------------------------------------------------
>
> Key: SPARK-43819
> URL: https://issues.apache.org/jira/browse/SPARK-43819
> Project: Spark
> Issue Type: Bug
> Components: PySpark, Spark Core
> Affects Versions: 3.3.2
> Reporter: Matthew Tieman
> Priority: Major
>
> When running a stage using barrier executor, the expectation is that a
> failure in a task will result in the stage being retried. However, if an
> exception is thrown from a task, the stage is not retried and the job fails.
> Running the pyspark code below will cause a single task to fail, failing the
> stage without retrying.
> {code:java}
> def test_func(index: int) -> list:
> if index == 0:
> raise RuntimeError("Thrown from test func")
> return []
> start_rdd = sc.parallelize([i for i in range(10)], 10)
> result = start_rdd.barrier().mapPartitionsWithIndex(lambda i, c: test_func(i))
> result.collect(){code}
>
> This failure is seen running locally via the pyspark shell and on a K8s
> cluster.
