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.
