missing jdbc driver error message in distributed mode

[Eugene Dvorkin]

One of my bolt should record data into SQL datastore. The application works fine in local mode. 

When I deploy it into cluster, even my cluster consist only on one server, I got 2013-03-20 09:39:33 STDIO [ERROR] java.sql.SQLException: No suitable driver found for jdbc:vertica:

I see error in worker log file.

My jar file contains all driver classes. I have verified it with 

 jar -tf build/libs/CPStorm-9.4.0.jar |grep vertica

and I got:

com/vertica/jdbc/

com/vertica/jdbc/AbstractDataSource.class

com/vertica/jdbc/AbstractDriver.class

com/vertica/jdbc/BaseConnectionFactory.class

com/vertica/jdbc/DataSource.class

com/vertica/jdbc/Driver.class

com/vertica/jdbc/JDBCObjectFactory.class

com/vertica/jdbc/SCallableStatement.class

com/vertica/jdbc/SConnection.class

and a lot of other classes.

What could be the reason for this error? 

Maybe driver was not transferred to the worker?

Thanks

Was my own problem:

I had to explicitly load jdbc driver before attempting to connect

log.info( 'try to load the vertica JDBC driver')

            Class.forName("com.vertica.jdbc.Driver");

            log.info("loaded vertica driver")

This is the difference from my local mode
