Matt McCline commented on HIVE-9743:
------------------------------------
[~vikram.dixit] I removed the annotations and the MR
vector_left_outer_join3.q.out and fiddled with environment variables so that it
now has "Sorted Merge Bucket Map Join Operator" operators; Tez has "Merge Join
Operator" as you said.
The original LEFT OUTER JOIN problem does not repro with
vector_left_outer_join3.q though.
> Incorrect result set for vectorized left outer join
