> from comments at the end of MRUNIT-66:
> Hadoop allows null keys and values, when not used as intermediate keys,values between
mappers and reducers. MRUnit should also allow allow null keys and values as output and expected
output. The Serialization class will need to be modified to not try to copy null's into the
output, expected output
