-------------------------------------------

             Summary: Streaming Analytics Manager (SAM) not working with 
PostgreSQL
                 Key: AMBARI-22580
                 URL: https://issues.apache.org/jira/browse/AMBARI-22580
             Project: Ambari
          Issue Type: Bug
          Components: ambari-server
            Reporter: Unai P. Mendizabal


Hi!

I was trying to install SAM on my Ambari cluster and trying to use the same 
PostgreSQL database I use for Ambari server. The installation fails though, 
with error "KeyError: 'jdbc_driver_jar" coming from the params.py file of the 
Streamline service. I dived into it and realized that variable 
'jdbc_driver_jar' is never initialized for PostgreSQL databases, while it does 
when it comes to Oracle or MySQL.

The file is 
/var/lib/ambari-server/resources/common-services/STREAMLINE/0.5.0/package/scripts/params.py,
 you can see the problem from line 192 on. As a workaround, I think it should 
be possible to manually set 'jdbc_driver_jar' to the path to the jdbc driver on 
that same file.
