Summary: Add early termination for recursion in StatsRulesProcFactory$FilterStatsRule.evaluateExpression for OR expression Key: HIVE-11405 URL: https://issues.apache.org/jira/browse/HIVE-11405 Project: Hive Issue Type: Bug Reporter: Hari Sankar Sivarama Subramaniyan Assignee: Prasanth Jayachandran Thanks for [~gopalv] for uncovering this as part of HIVE-11330. Quoting him, "The recursion protection works well with an AND expr, but it doesn't work against (OR a=1 (OR a=2 (OR a=3 (OR ...) since the for the rows will never be reduced during recursion due to the nature of the OR. We need to execute a short-circuit to satisfy the OR properly - no case which matches a=1 qualifies for the rest of the filters. Recursion should pass in the numRows - branch1Rows for the branch-2." -- This message was sent by Atlassian JIRA (v6.3.4#6332)
