It didn't vectorize merge-into statements using parquet files. Example select and the problematic output are in the ticket description: https://issues.apache.org/jira/browse/HIVE-26997 Sample qtest in the PR. ### What changes were proposed in this pull request? Allow vectorization for virtual column, PARTITION__SPEC__ID. Actually, when we vectorize partition spec id, it brings in extra virtual columns as well (see the change in Vectorizer.java ### Why are the changes needed? `Map notVectorizedReason: Select expression for SELECT operator: Virtual column PARTITION__SPEC__ID is not supported ` ### Does this PR introduce _any_ user-facing change? Only if they use `explain vectorization only detail` statement. ### How was this patch tested? With qtests added. -- This is an automated message from the Apache Git Service.
