Doğacan Güney updated HBASE-1725:
---------------------------------
Attachment: mapred.patch
Simple patch that relaxes to WritableComparable<? super K>.
Sorry this is a git patch.
> Old TableMap interface's definitions are not generic enough
> -----------------------------------------------------------
>
> Key: HBASE-1725
> URL: https://issues.apache.org/jira/browse/HBASE-1725
> Project: Hadoop HBase
> Issue Type: Improvement
> Affects Versions: 0.20.0
> Reporter: Doğacan Güney
> Priority: Minor
> Attachments: mapred.patch
>
>
> 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>.
