Eric Hanson created HIVE-4472: --------------------------------- Summary: OR Filter logic can lose an array, and always takes time O(DEFAULT_BATCH_SIZE) Key: HIVE-4472 URL: https://issues.apache.org/jira/browse/HIVE-4472 Project: Hive Issue Type: Sub-task Reporter: Eric Hanson Assignee: Jitendra Nath Pandey
The issue is in file FilterExprOrExpr.java I posted a review for you at https://reviews.apache.org/r/10752/ I think there is a bug related to sharing of an array of integers. Also, one algorithm step takes O(DEFAULT_BATCH_SIZE) time always. If n<<DEFAULT_BATCH_SIZE then this is a performance issue. -- This message is automatically generated by JIRA.
