[jira] [Created] (HIVE-14947) Add support for Acid 2 in Merge

Eugene Koifman created HIVE-14947:
-------------------------------------

             Summary: Add support for Acid 2 in Merge
                 Key: HIVE-14947
                 URL: https://issues.apache.org/jira/browse/HIVE-14947
             Project: Hive
          Issue Type: Sub-task
          Components: Transactions
            Reporter: Eugene Koifman
            Assignee: Eugene Koifman


HIVE-14035 etc introduced a more efficient data layout for acid tables
Additional work is needed to support Merge for these tables
Need to make sure we generate unique ROW__IDs in each branch of the multi-insert statement.  StatementId was introduced in HIVE-11030 but it's not surfaced from storage layer.  It needs to be made part of ROW__ID to ensure unique ROW__ID from concurrent writes from the same query.
