# Proposed changes
when nereids translates PhysicalHashAggreg node to original plan, if the
input fragment root is exchange node, nereids assumes that this exchanged node
is generated by PhyscialDistirbute node.
But this assumption is not true. For example, sort node could be translated
to exchange(merge phase)+sort(local phase).
Issue Number: close #xxx
