The function named assign conjuncts has been invoked before creating aggregation plan node. If the empty set node is the child of aggregation node, the conjuncts will be assign to empty set node which could not be executed correctly in Backend. It will thrown the exception "couldn't resolve slot descriptor" for query which has both empty set node and aggregation node. For example: select sum(pv) from test where type != 1 and 1=0 group by type; This commit fix this bug. It remove conjuncts for empty set node.
