> In old mapred package, TableMap is defined like this:
> public interface TableMap<K extends WritableComparable<K>, V extends Writable>
> I think the "WritableComparable<K>" part is new, because some of my old code does not compile with hbase 0.20. Specifically, you can not output  a hadoop.io.Text from TableMap as Text implements WritableComparable<BinaryComparable> and not WritableComparable<Text>.
