Nick Dimiduk created FLINK-3228:
-----------------------------------
Summary: 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: Streaming
Affects Versions: 0.10.1
Reporter: Nick Dimiduk
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.
