Harish Butani commented on HIVE-7283:
-------------------------------------
ok, sorry was running cbo_correctness.q w/o setting hive,enable.cbo=true on
command line.
I see the issue: for semiJoins joinType is set to Inner on JoinRelBase, so the
assertion that num cols in Join = left + right fails in
RelOptUtil.classifyFilters
For now going to bail in HivePushFilterPastJoinRule for SemiJoins. Should have
a patch soon.

> 1.
> HepPlanner initially used for:
> - Predicate Pushdown
> - Transitive Predicate inference
> - Partition Pruning
> 2. Use Optiq's FieldTrimmer for ColumnPruner
> To begin with the rules are copies of Optiq base rules. Once Optiq is
> refactored to work on Base RelNode classes, the copied rules will be removed.
