[jira] [Created] (HIVE-18132) Acid Table: Exchange Partition

Eugene Koifman created HIVE-18132:
-------------------------------------

             Summary: Acid Table: Exchange Partition
                 Key: HIVE-18132
                 URL: https://issues.apache.org/jira/browse/HIVE-18132
             Project: Hive
          Issue Type: New Feature
          Components: Transactions
            Reporter: Eugene Koifman


This command currently renames a directory under 1 table to be under another table's name space.  This can't work for Acid since data itself has embedded transaction info.

If src is not full acid, it could be added to target side like Load Data - into delta/base, but if source side is also Acid the IDs won't make sense in target table.  It could match if using global txn ids but may not match with per table write ids if some ID from src is committed but the same ID in target is aborted.


Does this command currently work with bucketed tables?
