Add a option to run task to check map-join possibility in non-local mode ------------------------------------------------------------------------
Key: HIVE-1831 URL: https://issues.apache.org/jira/browse/HIVE-1831 Project: Hive Issue Type: Improvement Components: Query Processor Reporter: Namit Jain Assignee: Liyin Tang In HIVE-1642, we run a local task to figure out if the small table can be held in memory, and then convert the join into a map-join. However, this can be a good idea for thin clients (which may not have enough memory). This should be made configurable - where the default can still be to run the task locally on the client machine, but an option should be added for thin clients, where the task would be run as a map-only task -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
