Thanks Gunther! > Enable hash joins using tez > --------------------------- > > Key: HIVE-5270 > URL: https://issues.apache.org/jira/browse/HIVE-5270 > Project: Hive > Issue Type: Bug > Components: Tez > Affects Versions: tez-branch > Reporter: Vikram Dixit K > Assignee: Vikram Dixit K > Attachments: BroadCastJoinsHiveOnTez.pdf, HIVE-5270.1.patch, HIVE-5270.2.patch, HIVE-5270.4.patch > > > 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 was sent by Atlassian JIRA (v6.1#6144)
