Steve Loughran commented on HADOOP-5201:
----------------------------------------
I should add that I'd like this feature purely for better logging; no plans to
rethrow them. If this is also what Santhosh wants, we don't need to do the
tricks of creating a new Throwable chain, just have a general purpose writeable
representation of an exception.
This my SOAP stack equivalent

> Currently, getDiagnostics() returns Strings. When exceptions are thrown in
> user code and/or Hadoop, it would be cleaner to propagate the exception back
> to the application for better error handling. Hadoop should return the
> exceptions instead of returning string representations that correspond to
> printStackTrace() output.
