------------------------------------
Summary: SMB join small table side should use the same set of
serialized payloads across tasks
Key: HIVE-8597
URL: https://issues.apache.org/jira/browse/HIVE-8597
Project: Hive
Issue Type: Improvement
Components: Tez
Affects Versions: 0.14.0
Reporter: Siddharth Seth
Assignee: Siddharth Seth
Fix For: 0.14.0
Each task sees all splits belonging to the bucket being processed by the task.
At the moment, we end up using different instances of the same serialized split
which adds unnecessary memory pressure.
