UNION ALL should create different destination directories for different
operands
Key: HIVE-308
URL: https://issues.apache.org/jira/browse/HIVE-308
Project: Hadoop Hive
Issue Type: Bug
Components: Query Processor
Affects Versions: 0.3.0
Reporter: Zheng Shao
Assignee: Zheng Shao
Priority: Blocker
Fix For: 0.3.0
Attachments: HIVE-308.1.patch
The following query hangs:
{code}
select * from (select 1 from zshao_lazy union all select 2 from zshao_lazy) a;
{code}
The following query produce wrong results: (one map-reduce job
overwrite/cannot overwrite the result of the other)
{code}
select * from (select 1 as id from zshao_lazy cluster by id union all select
2 as id from zshao_meta) a;
{code}
The reason of both is that the destination directory of the file sink
operator conflicts with each other.

Zheng, there are a lot of problems with union, and I am in the process of
fixing them in:
https://issues.apache.org/jira/browse/HIVE-318
Some corner cases are not working, and I should be done hopefully in a day or 2.
Can you hold on to this patch - let us look at these 2 patches together and
then decide

Explain extended also shows 2 file sink operator. But it's possible that there
is only 2 and get displayed TWICE (and also initialized TWICE during query
execution)
