Looks great for me. I've verified 'mvn clean install'.

> URL: https://issues.apache.org/jira/browse/TAJO-232
> Project: Tajo
> Issue Type: Improvement
> Components: physical operator
> Reporter: Hyunsik Choi
> Assignee: Hyunsik Choi
> Fix For: 0.2-incubating
>
> Attachments: TAJO-232_2.patch, TAJO-232.patch

>
> The current physical operators for join have different naming rules as
> follows:
> * LeftOuterHashJoin, FullOuterHashJoin, ...
> * HashSemiJoin, HashAntiJoin
> This patch renames join operators with consistency as follows:
> * {Algorithm}{Join Type} Join
> For example, outer joins will have the following names:
> * HashLeftOuterJoin
> * MergeRightOuterJoin
> * HashFullOuterJoin
> This patch adds other join algorithms (left semi/anti hash join) to physical
> operators and adds In-subquery clause and exists predicate to Tajo algebra.
