Deepak Jaiswal created HIVE-16947: ------------------------------------- Summary: Semijoin Reduction : Task cycle created due to multiple semijoins in conjunction with hashjoin Key: HIVE-16947 URL: https://issues.apache.org/jira/browse/HIVE-16947 Project: Hive Issue Type: Bug Reporter: Deepak Jaiswal Assignee: Deepak Jaiswal
Typically a semijoin branch and a mapjoin may create a cycle when on same operator tree. This is already handled, however, a semijoin branch can serve more than one filters and the cycle detection logic currently only handles the 1st one causing cycles preventing the queries from running. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
