The assertion that is not met is the following:
{code}
@Override
public Project copy(RelTraitSet traitSet, RelNode input, List<RexNode>
exps,
RelDataType rowType) {
assert traitSet.containsIfApplicable(HiveRelNode.CONVENTION);
return new HiveProject(getCluster(), traitSet, input, exps, rowType,
getFlags());
}
