[jira] [Commented] (HIVE-8474) Vectorized reads of transactional
tables fail when not all columns are selected
[ https://issues.apache.org/jira/browse/HIVE-8474?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14175664#comment-14175664 ]
Alan Gates commented on HIVE-8474:
----------------------------------
Further testing has also determined that attempts to select a partition column in vectorization results in a NPE as well.
