Siddharth Seth created HIVE-8597: ------------------------------------ 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
