> Faling to re-raise exceptions
> -----------------------------
>
> Key: BEAM-1901
> URL: https://issues.apache.org/jira/browse/BEAM-1901
> Project: Beam
> Issue Type: Bug
> Components: sdk-py-core
> Reporter: Ahmet Altay
> Priority: P3
>
> In runners common.py {{reraise_augmented}} fails to re-raise exceptions in
> some case.
> {{raise type(exn), args, sys.exc_info()[2]}}
> The above code assumes that the Exception can be reconstructed from its
> arguments but this is not always true for custom exception classes. (e.g.
> {{RPCError}} in
> https://github.com/GoogleCloudPlatform/google-cloud-datastore/blob/master/python/googledatastore/connection.py#L226
> This re-raising could first attempt to re-create the exception and if that
> does not fail raise otherwise raise the original exception as is.
