Vikram Dixit K commented on HIVE-9038:
--------------------------------------
This issue as Navis mentioned, stems from the fact that tez does not make
filterTag. FilterTag is generated in case of MR by the HashTableSinkOperator
which is not used in case of tez. The right solution would be to have a select
operator that adds the filtertag to the value field so as to work without
sacrificing the increased stages by moving this to a shuffle join instead of
map join. However, since this only happens in the case where there are multiple
joins on the same key with an outer join doing the filtering, I have this patch
that changes the join to a shuffle join in this case for the time being so as
to get away from the asserts. I will be raising a different jira for the good
fix.
