# Proposed changes
Issue Number: close #xxx
## Problem summary
cross join node has no output tuple for itself. Instead, use its children'
tuple info instead. The hash join node set the output slot's nullable info
based on its children' tuple info. So if the child is cross join node, hash
join node should check if the cross join node's tuples is out joined, then can
set the slots nullable info correctly.
