Prasanth J commented on HIVE-8740: ---------------------------------- [~alangates] Can you look at the test case that I added in this patch? Its related to ACID DELETE operation. After deleting a newly added row, the select count\(*\) query return 0 rows instead of actual 1000 rows. Is this a bug/known issue or am I doing something wrong? > Sorted dynamic partition does not work correctly with constant folding > ---------------------------------------------------------------------- > > Key: HIVE-8740 > URL: https://issues.apache.org/jira/browse/HIVE-8740 > Project: Hive > Issue Type: Bug > Affects Versions: 0.14.0 > Reporter: Prasanth J > Assignee: Prasanth J > Attachments: HIVE-8740.1.patch > > > Sorted dynamic partition optimization looks for partition columns from the > operator above FileSinkOperator. As per hive convention it expects partition > columns at the last. But with HIVE-8585 equality filters on partition columns > gets folded to constant. The column pruner then prunes the constant > expression as they don't reference any columns. This in some cases will yield > unexpected results (throw ArrayIndexOutOfBounds exception) with sorted > dynamic partition insert optimization. In such we don't really need sorted > dynamic partition optimization. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
