> Key: TAJO-34
> URL: https://issues.apache.org/jira/browse/TAJO-34

> Issue Type: New Feature
> Reporter: Hyunsik Choi
> Assignee: camelia c
> Labels: gsoc, gsoc2013, join, mentor
>
> h3. Background
> The current Tajo does not support outer join. The parser part for outer join
> was already implemented.
> h3. Proposal
> In this issue, we should improve LogicalPlanner/LogicalOptimizer to deal with
> outer joins. Then, we should adopt outer join to existing physical join
> operators like HashJoinExec and MergeJoinExec.
