   I think I have found the way to solve the problem:
   I can use multi alter stmt like: 
   **alter table test_table add column another_col BIGINT SUM NULL default "0" to rollup1, add column another_col BIGINT SUM NULL default "0" to rollup2**
   It will lock table until 3 ddl tasks all finish 
   Maybe we can add some docs....
