Gyula Fora commented on FLINK-3228:
-----------------------------------

I remember having similar issues. What worked for me is to explicitly call 
Class.forName(driverClass) before trying to create the connection with the 
DriverManager.

Could you please try this?

>             Project: Flink
>          Issue Type: Bug

> I have a streaming pipeline that writes to JDBC in its SinkFunction. When 
> testing in local mode, I cannot submit the same job multiple times without 
> restarting flink. Failing to restart flink results in 
> {{java.sql.SQLException: No suitable driver found}}. I think this has to do 
> with how flink loads user classes and how the {{DriverManager}} resolves the 
> JDBC Connection class.
> I'm not sure if this is only when running in local mode, or in general. I've 
> been using YARN for cluster jobs, where I have 1:1 cluster to jobs. I suspect 
> it will impact any cluster mode where processes are recycled between jobs.
