Chao commented on HIVE-8934:
----------------------------
Xuefu, the change on MapJoinTableContainerSerDe is for Spark only, and the
change for MapJoinEagerRowContainer won't affect MR/Tez, I think.
In this test, the table is first partitioned and then bucketized. So the HTS
would still generate different files with same key.
> Investigate test failure on bucketmapjoin10.q and bucketmapjoin11.q [Spark

> With MapJoin enabled, these two tests will generate incorrect results.
> This seem to be related to the HiveInputFormat that these two are using.
> We need to investigate the issue.
