> If there is a column reference within subquery which doesn't exist Hive throws misleading error message.
> e.g.
> {code:sql}
> select * from table1 where table1.col1 IN (select col2 from table2 where table2.col1=table1.non_existing_column) and table1.col1 IN (select 4);
> {code}
> The above query, assuming table1 doesn't have non_existing_column, will throw following misleading error:
> {noformat}
> FAILED: SemanticException Line 0:-1 Unsupported SubQuery Expression 'col1': Only 1 SubQuery expression is supported.
> {noformat}
