> {noformat}
> hive> select *, INPUT__FILE__NAME FROM t1, t2;
> FAILED: SemanticException Column INPUT__FILE__NAME Found in more than One Tables/Subqueries
> {noformat}
> The build-in functions {{input_file_name}}, {{input_file_block_start}}, {{input_file_block_length}} do not support more than one sources, like what Hive does. Currently, we do not block it and the outputs are ambiguous.
