Szehon Ho commented on HIVE-8934:
---------------------------------
+1, Looked at test with Chao, for this test the table is bucketed and
partitioned and so it will have duplicate keys across bucket files, leading to
the overwrite.
> Investigate test failure on bucketmapjoin10.q and bucketmapjoin11.q [Spark
> Branch]

> 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.
