> Pig already has couple of map-side join implementations: Merge Join and
> Fragmented-Replicate Join. But both of them are pretty restrictive. Merge
> Join can only join two tables and that too can only do inner join. FR Join
> can join multiple relations, but it can also only do inner and left outer
> joins. Further it restricts the sizes of side relations. It will be nice if
> we can do map side joins on multiple tables as well do inner, left outer,
> right outer and full outer joins.
> Lot of groundwork for this has already been done in PIG-1309. Remaining will
> be tracked in this jira.
