> Cannot submit multiple streaming involving JDBC drivers
> -------------------------------------------------------
>
> Key: FLINK-3228
> URL: https://issues.apache.org/jira/browse/FLINK-3228
> Project: Flink
> Issue Type: Bug
> Components: API / DataStream
> Affects Versions: 0.10.1
> Reporter: Nick Dimiduk
> Priority: Major
> Labels: stale-major
>
> 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.
