      Description

      In hive for union alls the query has to be wrapped in an sub query as shown below:

      select * from
      (select c1 from t1
      union all
      select c2 from t2);

      This JIRA proposes to fix that to support

      select c1 from t1
      union all
      select c2 from t2;
