Hi Hive developers, Could anyone please review the two issues below or assign familiarized persons? I have opened two issues and created patches. They would fix lines that have no recent changes and I have no idea who should review them. So I would like someone familiar to take a look when they have a chance.
1. HIVE-22601 This issue can eliminate columns from a result when multiple aliases and UNION are combined. I have observed this one when I used Hivemall which provides many useful ML features. The following PR would prevent ParseUtils from rewriting an AST in the wrong manner. https://github.com/apache/hive/pull/2042 2. HIVE-24606 This issue can silently drop rows generated by previous and dependent tasks. I faced this issue when CTE materialization is enabled. The next major version will probably enable it by default. The following PR would let SemanticAnalyzer link correct dependencies between tasks. https://github.com/apache/hive/pull/1873 Please feel free to ask me on JIRA or GitHub if you have questions. Thanks, Okumin
