-------------------------------------
Summary: Hive on Tez: Shuffle joins do not choose the right 'big'
table.
Key: HIVE-13518
URL: https://issues.apache.org/jira/browse/HIVE-13518
Project: Hive
Issue Type: Bug
Reporter: Vikram Dixit K
Assignee: Vikram Dixit K
Currently the big table is always assumed to be at position 0 but this isn't
efficient for some queries as the big table at position 1 could have a lot more
keys/skew. We already have a mechanism of choosing the big table that can be
leveraged to make the right choice.
