>
> While debugging an issue I noticed that during EXPLAIN the following methods
> throw a NullPointerException:
> VectorColumnOutputMapping::finalize
> AbstractOperatorDesc::getUserLevelStatistics
> AbstractOperatorDesc::getColumnExprMapForExplain
> The exceptions do end up getting caught but we should add null checks and
> gracefully to be less wasteful and to aid future debugging.
