morgan created FLINK-16933:
------------------------------
Summary: No suitable driver found for jdbc:xxx
Key: FLINK-16933
URL: https://issues.apache.org/jira/browse/FLINK-16933
Project: Flink
Issue Type: Bug
Components: API / DataStream
Affects Versions: 1.9.0
Environment: CentOS Linux release 7.7.1908 (Core)
Reporter: morgan
For example, there are two streaming jobs A and B.
When A calculation is running, I submit B, at this time, an exception will be
thrown, Caused by: java.sql.SQLException: No suitable driver found for jdbc:
clickhouse: // host: 8123 / data. When stopping flink ./stop-cluster.sh. Then
restart ./start-cluster.sh. When flink is not running any tasks, submit B, and
B is successfully executed. But if you execute B multiple times, Caused by:
java.sql.SQLException: No suitable driver found for jdbc: clickhouse: // host:
8123 / data will also be thrown. Both B and A depend on clickhouse4j in the
common. A submission can run normally, but B can only be executed when restart
and flink does not contain other tasks, which seems strange. I checked flink /
lib / and clickhouse4j-1.4.1.jar has been added. I tried to package
clickhouse4j-1.4.1.jar into the job, but still couldn't solve this problem. I
tried to add it to jre / lib / ext and added it to the classpath. The problem
was not solved. But I executed in the local environment idea and did not throw
any exception.
