@EnricoMi @cloud-fan Could we fix the `DeduplicateRelations`? It did not
generate different expression IDs for all conflicting attributes:
```
=== Applying Rule
org.apache.spark.sql.catalyst.analysis.DeduplicateRelations ===
Join LeftSemi Join LeftSemi
:- Project [(id#4 + 1) AS id#6] :- Project [(id#4 + 1) AS id#6]
: +- Deduplicate [id#4] : +- Deduplicate [id#4]
: +- Project [value#1 AS id#4] : +- Project [value#1 AS id#4]
: +- LocalRelation [value#1] : +- LocalRelation [value#1]
+- Deduplicate [id#4] +- Deduplicate [id#4]
! +- Project [value#1 AS id#4] +- Project [value#8 AS id#4]
! +- LocalRelation [value#1] +- LocalRelation [value#8]
```
