Jason Dere commented on HIVE-6688:
----------------------------------
The following tests look like they can be fixed by adding order-by:
groupby1_limit
groupby1_map
groupby1_map_skew
groupby1_noskew
groupby2_limit
groupby2_map
groupby2_map_multi_distinct
groupby2_map_skew
groupby2_noskew
groupby2_noskew_multi_distinct
groupby4_noskew
groupby5_noskew
groupby6_map
groupby6_map_skew
groupby6_noskew
groupby7_map
groupby7_map_multi_single_reducer
groupby7_map_skew
groupby7_noskew
groupby7_noskew_multi_single_reducer
groupby8_map
groupby8_map_skew
groupby8_noskew
groupby_map_ppr
groupby_map_ppr_multi_distinct
groupby_resolution
The following 3 tests cases seem to be failing due to different issues:
groupby3_map_skew: variance result seems to have different number of double
digits
groupby_sort_1: numfiles different
groupby_sort_skew_1: numfiles different
> Fix groupby_* qfile failures in hadoop-2

> Bunch of the groupby_* tests fail on hadoop-2, many of them look like they
> require an order-by to be added in the queries to make the results repeatable
> between hadoop-1/hadoop-2.
