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.
