Key: HIVE-20142 URL: https://issues.apache.org/jira/browse/HIVE-20142 Project: Hive Issue Type: Task Reporter: Deepak Jaiswal Assignee: Deepak Jaiswal
The semijoin reduction removal logic is spread out into multiple functions. Currently, the cost based removal logic is applied before the rule based(dumb) ones. Instead, apply the rule based removal logic and then apply the cost based removal. cc [~jdere] [~jcamachorodriguez] -- This message was sent by Atlassian JIRA (v7.6.3#76005)
