Hi,

I was planning to use DataJoin jar (located in
$HADOOP_INSTALL/contrib/datajoin) for reduce-side join (version 1.0.3).

It looks like DataJoinMapperBase implements Mapper interface (according
to old API) and not extends it (according to new API). This is a problem
because I cannot write Map classes that extend DataJoinMapperBase.

Do we have newer version of data join jar?

Thanks.

Hi,

Do we not have any info on this? Join must be such a common scenario for
most of the people out on this list.

Thanks.

DataJoin is an example. Most people doing joins use Hive or Pig rather
then code them up themselves.
