Subject How does org.apache.hadoop.mapred.join work?
Date Mon, 14 Jul 2008 16:20:35 GMT

I find limited information about this package which looks like could
do "equi?" join. "Given a set of sorted datasets keyed with the same
class and yielding equal partitions, it is possible to effect a join
of those datasets prior to the map. " What does "yielding equal
partitions" mean?

Thank you.
