Description

I have a unit test that reuses the same ReduceDriver with 2 different sets of inputs. With 1.0.0, the second call to reduceDriver.run() returns the first run's outputs as well as the second's. This is a regression since 0.9.0-incubating.

Pseudocode:

// called twice
reduceDriver.setInputKey(key);
for (int i = 0; i < 5 ; ++i)

{ reduceDriver.addInputValue(v); }

List<Pair<K, V>> outputs = reduceDriver.run();
