Rui Li commented on HIVE-18831:
-------------------------------
How about we register a custom serializer for {{JobResult}}, which can try to
serialize the Throwable like {{JavaSerializer}} and fall back to stack trace
string if that fails? And we can use an extra boolean to indicate whether the
Throwable is serialized, so that the deserializer can deserialize accordingly.
> Differentiate errors that are thrown by Spark tasks

> We propagate exceptions from Spark task failures to the client well, but we
> don't differentiate between errors from HS2 / RSC vs. errors thrown by
> individual tasks.
> Main motivation is that when the client sees a propagated Spark exception its
> difficult to know what part of the excution threw the exception.
