Namit Jain commented on HIVE-4018:
----------------------------------
The following slightly simpler query also fails:
select * from fact
Left outer join dim1 on fact.d1= dim1.f1
Left outer Join dim3 on fact.d2= dim3.f5
Left outer Join dim4 on dim3.f6= dim4.f7
Left outer join dim5 on dim4.f8= dim5.f9
Left outer Join dim6 on dim3.f6= dim6.f11;
The basic problem is that MapJoinMetaData is a static - it should be per
HashTableSink operator.
This is a existing problem, and as such has nothing to do with the previous
cleanup.
I will try to fix this.
