> 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.
