Review comment:
Thanks. I guess it seems inconsistent to send the stdout/stderr information
along with the error in only one out of the three exceptions handled by this
method. Admittedly, I don't understand the codebase well enough to know why
this has been written this way. Approving as your changes address FLINK-12259
