Subject [jira] [Commented] (DRILL-911) Group by queries don't work with hbase
Date Thu, 05 Jun 2014 17:33:02 GMT

    [ https://issues.apache.org/jira/browse/DRILL-911?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14019000#comment-14019000
] 

Norris Lee commented on DRILL-911:
----------------------------------

Ah, ok. It works. The reason I filed this is because when you try and query data from an hbase
table using Tableau, Tableau generates this query:
{code}
SELECT `TableauSQL`.`account` AS `none_account_nk`
FROM (
  select * from `hbase`.`students`
) 
`TableauSQL`
GROUP BY `TableauSQL`.`account`
{code}

> Group by queries don't work with hbase
