Description

I have tested the latest Calcite snapshot against Hive.

We get the following exception when we create a Project
operator copy, that we were not getting in 1.2:

The assertion that is not met is the following:

  @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());
  }
