MRunit ReduceDriver does not fully replicate the reducers behaviour with
reusing pointers over the iterator
-----------------------------------------------------------------------------------------------------------
Key: MAPREDUCE-2546
URL: https://issues.apache.org/jira/browse/MAPREDUCE-2546
Project: Hadoop Map/Reduce
Issue Type: Bug
Components: contrib/mrunit
Affects Versions: 0.21.0, 0.20.2, 0.20.1
Reporter: Dan Harvey
Priority: Minor
The MRunit ReduceDriver does not replicate the behaviour of re-using the
pointer to the returned values as they are iterated over. This is a problem for
testing as it does not fail when you are incorrectly storing this pointer for a
value if you want to use it later on in the iteration over the values.
The behaviour should be modified so the iterator will return the same pointer
every time.
