Review request for hive, Szehon Ho and Xuefu Zhang.
Bugs: HIVE-8610
https://issues.apache.org/jira/browse/HIVE-8610
Repository: hive-git
Description
-------
This patch adds QBJoinTree and colExprMap for the cloned join operator tree in
SkewJoinOptimizer, so that CommonJoinResolver can properly convert the cloned
join to map join.
The added tests are copied from skewjoinopt*.q, except that auto map join is
enabled.
