-------------------------------------

             Summary: delete_deleta_x_x cannot modify delta_x_x
                 Key: HIVE-17127
                 URL: https://issues.apache.org/jira/browse/HIVE-17127
             Project: Hive
          Issue Type: Improvement
    Affects Versions: 2.2.0
            Reporter: Eugene Koifman
            Assignee: Eugene Koifman
            Priority: Minor


with split update an update statement will produce delete_deleta_x_x and delta_x_x for any
auto commit txn.  For multi-statement txn delete_delta_x_x_k may modify delta_x_x_j for j
< k.
Since we generate splits from delta_x_x there may be a small optimization here.
