Description

hive> select *, INPUT__FILE__NAME FROM t1, t2;
FAILED: SemanticException Column INPUT__FILE__NAME Found in more than One Tables/Subqueries

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.
