[jira] [Commented] (PHOENIX-1580) Support UNION ALL

    [ https://issues.apache.org/jira/browse/PHOENIX-1580?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14305940#comment-14305940 ] 

Alicia Ying Shu commented on PHOENIX-1580:
------------------------------------------

Attached please find the implementation for supporting chained top level Union Alls. It is work in-progress. I tested it with multiple Union all selects (select * from t1 union all select * from t2 union all select * from t3) and got correct results back.
