Apache Spark reassigned SPARK-8625:
-----------------------------------
Assignee: Apache Spark
> Propagate user exceptions in tasks back to driver
> -------------------------------------------------
>
> Key: SPARK-8625
> URL: https://issues.apache.org/jira/browse/SPARK-8625
> Project: Spark
> Issue Type: Improvement
> Components: Spark Core
> Affects Versions: 1.4.0
> Reporter: Tom White
> Assignee: Apache Spark
>
> Runtime exceptions that are thrown by user code in Spark are presented to the
> user as strings (message and stacktrace), rather than the exception object
> itself. If the exception stores information about the error in fields then
> these cannot be retrieved.
> Exceptions are Serializable, so it would be feasible to return the original
> object back to the driver as the cause field in SparkException. This would
> allow the client to retrieve information from the original exception.
