-------------------------------
Attachment: PIG-3747-2.patch
Thanks Daniel. I changed the table names in the example query-
{code}
A = LOAD 'skewed_data' AS (a1,a2,a3);
B = LOAD 'data' AS (b1,b2,b3);
C = JOIN A BY a1, B BY b1 USING 'skewed';
{code}

> While working on Tez skewed join, I found two problems with the skewed join
> documentation-
> # The following is misleading because skewed join also works with left,
> right, and full outer joins.
> {quote}
> Skewed join works with two-table inner join.
> {quote}
> # In two-way join, the 1st table must be the skewed one because Pig samples
> on that. But this is not mentioned anywhere.
