Bertrand Dechoux commented on MRUNIT-158:
-----------------------------------------
If the user don't want or can't change the implementations of the key/value
classes, a solution is to use the run() method of the drivers and check by
themselves that the outputs are what they should be.
List<Pair<?, ?>> outputs = driver.run();
But we agree that's quite a verbose solution for something that should be
trivial.
> withOutput doesn't generate useful information with MapWritable on error
