> UniqueJoin was introduced in HIVE-591. Add Unique Join. (Emil Ibrishimov via
> namit). It sounds like that there is only one q test for unique join, i.e.,
> uniquejoin.q. In the q test, unique join source can only come from a table.
> However, in parser, its source can come from not only tableSource, but also
> {code}
> partitionedTableFunction | tableSource | subQuerySource | virtualTableSource
> {code}
> I think it would be better to change the parser and limit it to meet the
> user's real requirement.
