> Key: TAJO-609
> URL: https://issues.apache.org/jira/browse/TAJO-609
> Project: Tajo
> Issue Type: Bug
> Components: planner/optimizer
> Reporter: Hyunsik Choi
> Assignee: Hyunsik Choi
> Fix For: 0.8-incubating

> Attachments: TAJO-609.patch

>
> Currently, PlannerUtil::getRelationLineage ignores PartitionedTableScanNode.
> As a result, PlannerUtil::getRelationLineage can return empty relations. It
> results in wrong estimation of relation size. Finally, in the case where a
> broadcast join between a partitioned table and a small table, this problem
> causes the bug to choose the larger table instead of smaller one to be loaded
> on hash table.
> This patch fixes this bug, refactors inner-join related methods, and added
> more comments on them.
