Summary: Exchange partition should not be supported with per table write ID. Key: HIVE-18750 URL: https://issues.apache.org/jira/browse/HIVE-18750 Project: Hive Issue Type: Sub-task Components: HiveServer2, Transactions Affects Versions: 3.0.0 Reporter: Sankar Hariappan Assignee: Sankar Hariappan Fix For: 3.0.0 Per table write id implementation (HIVE-18192) have introduced write ID per table and used write ID to name the delta/base files and also as primary key for each row. Now, exchange partition have to move delta/base files across tables without changing the write ID which causes incorrect results. Also, this exchange partition feature is there to support the use-case of atomic updates. But with ACID updates, we shall support atomic-updates and hence it makes sense to not support exchange partition for ACID and MM tables. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
