> Ran into this one today: Writables.registerComparable won't actually change the sorting
strategy for custom writables inside of tuples b/c we don't necessarily initialize the WRITABLE_CODES
with the serialized contents of the Configuration instance in the map/reduce phases of the
job, where the codes are actually written out.
> Adding the initialization to the TupleTWMapFn and TWTupleMapFn inside of Writables.java
fixes the problem.
