Chao commented on HIVE-9026:
----------------------------
What I've found is:
- test result depends on the # of reducers. When the # of reducers is larger
than 1, the result may be wrong.
- # of reducers may depends on whether a query is executed alone, or together
with other queries.
subquery_in.q is an example for the above issues. Right now,
ppd_multi_insert.q, subquery_in.q and join_nullsafe.q all have different
results because of the above.
The same issue also present in the trunk. To reproduce, just add "set
mapred.reduce.tasks=3" to subquery_in.q, and run the test. I'm still not sure
what is the exact reason for this.
> Re-enable remaining tests after HIVE-8970 [Spark Branch]
