[Ramesh Reddy (JIRA)]

     [ https://issues.jboss.org/browse/TEIID-2647?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Ramesh Reddy updated TEIID-2647:
--------------------------------

    Fix Version/s: 8.7.1
         Assignee: Ramesh Reddy  (was: Steven Hawkins)


Impala uses same JDBC driver as Hive, however Impala implements a different engine on the server side than Hive. That is difference between both offerings.

The JDBC driver is designed more of a pass though of your SQL/HQL queries, so vendor specific extensions are not highlighted.  As long as user uses generic queries they works fine, as soon as they use specific query to match vendor specification Hive translator fails. Thus writing a Impala translator is required.
