             Summary: Eliminate file rename in insert-only compactor
                 Key: HIVE-22971
                 URL: https://issues.apache.org/jira/browse/HIVE-22971
             Project: Hive
          Issue Type: Improvement
            Reporter: Karen Coppage


File rename is expensive for object stores, so MM (insert-only) compaction 
should skip that step when committing and write directly to base_x_cZ or 
delta_x_y_cZ.
