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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
