Vikram Dixit K created HIVE-5270: ------------------------------------ Summary: Enable hash joins using tez Key: HIVE-5270 URL: https://issues.apache.org/jira/browse/HIVE-5270 Project: Hive Issue Type: Sub-task Components: Tez Affects Versions: tez-branch Reporter: Vikram Dixit K Assignee: Vikram Dixit K
Since hash join involves replicating a hash table to all the map tasks, an equivalent operation needs to be performed in tez. In the tez world, such an operation is done via a broadcast edge (TEZ-410). We need to rework the planning and execution phases within hive for this. -- This message is automatically generated by JIRA.
