> The SplitCallable.call method in AbstractColumnFamilyInputFormat has the following code for building ColumnFamilySplits:
> {noformat}
>             for (TokenRange subSplit : subSplits.keySet())
>             {
>                 List<TokenRange> ranges = subSplit.unwrap();
>                 for (TokenRange subrange : ranges)
>                 {
>                     ColumnFamilySplit split =
>                             new ColumnFamilySplit(
>                                     subrange.getStart().toString().substring(2),
>                                     subrange.getEnd().toString().substring(2),
>                                     subSplits.get(subSplit),
>                                     endpoints);
>                     logger.debug("adding {}", split);
>                     splits.add(split);
>                 }
>             }
> {noformat}
> The subrange.getStart().toString().substring(2) works for the OrderPreservingPartitioner because the toString for the OPPToken in the java driver returns a hex value preceded by 0x. It doesn't work for the Murmur3Partitioner because the toString for the M3PToken returns Long.toString.
> As a result the tokens lose their first 2 digits.
