This is good to know. Could you perhaps raise an issue in the Hive JIRA?

The implementation in hive does look wrong. The concept of VertexGroups was
added in Tez specifically for the case of union to support writing to same

Thanks Elliot. Nice christmas present. Those settings in that

Presumably this is to prevent multiple tasks from attempting to write the
same file?
We've experienced issues when switching from mr to tez; downstream jobs

Are there any exceptions in hive.log?. Is tmp_pv_v4* table part of the
select query?
Assuming you are creating the table in staging.db, it would have created
the table location as staging.db/foo (as you have not specified the
location).
Adding user@hive.apache.org as this is hive related.
