[teiid-issues] [JBoss JIRA] (TEIID-2647) Add an impala translator

[Ramesh Reddy (JIRA)]

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

Ramesh Reddy resolved TEIID-2647.
---------------------------------

        Labels: alpha1  (was: )
    Resolution: Done


Added a new impala translator which derives from same code base as the hive translator. Modifications from Hive translator are
* data type support
* function support
* removed few capabilities like enhanced aggregation functions, array support
* added capabilities for having clause, with clause, row offset

Looked through Cloudera's SQL reference once for any more features to implemented, but they JOIN capability seems to be similar to Hive. Any other issues will be dealt as individual separate issues in terms of capabilities missing or different.
