Jason Dere created HIVE-11262: --------------------------------- Summary: Skip MapJoin processing if the join hash table is empty Key: HIVE-11262 URL: https://issues.apache.org/jira/browse/HIVE-11262 Project: Hive Issue Type: Improvement Components: Query Processor Reporter: Jason Dere Assignee: Jason Dere
Currently the map join processor processes all rows of the big table, even when the hash table is empty. If it is an inner join, we should be able to skip the join processing, since the result should be empty. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
