Left semi join does not allow filter on right table
---------------------------------------------------
Key: HIVE-2325
URL: https://issues.apache.org/jira/browse/HIVE-2325
Project: Hive
Issue Type: Bug
Components: Query Processor
Affects Versions: 0.7.1
Reporter: Charles Chen
Given
{noformat}
create table invites (foo int, bar string) partitioned by (ds string);
create table invites2 (foo int, bar string) partitioned by (ds string);
explain select * from invites left semi join invites2 on invites.ds=invites2.ds
where invites2.ds='2011-01-01';
{noformat}
an error:
{noformat}
FAILED: Error in semantic analysis: Line 1:86 Invalid table alias or column
reference 'invites2': (possible column names are: _col0, _col1, _col2)
{noformat}
is returned.
Presumably the groupby operation in the semi join doesn't preserve the column
names?
