             Summary: MM tables: add exchange partition test after ACID 
integration
                 Key: HIVE-16052
                 URL: https://issues.apache.org/jira/browse/HIVE-16052
             Project: Hive
          Issue Type: Sub-task
            Reporter: Sergey Shelukhin


exchgpartition2lel test fails if all tables are changed to MM, because of write 
ID mismatch between directories and tables when exchanging partition 
directories between tables. ACID should probably fix this because transaction 
IDs are global.
We should add a test after integrating with ACID; if it doesn't work for some 
other reason, we can either implement it as moving to a new mm_id/txn_id in 
each affected partition, or block it on MM tables.
