> Fix caught NullPointerExceptions generated during EXPLAIN

> Key: HIVE-22252
> URL: https://issues.apache.org/jira/browse/HIVE-22252
> Project: Hive
> Issue Type: Bug
> Reporter: John Sherman
> Assignee: John Sherman
> Priority: Minor
> Attachments: HIVE-22252.1.patch
>
>
> 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.
