> Key: FLINK-20657

> Project: Flink
> Issue Type: Improvement
> Components: Connectors / JDBC, Table SQL / Ecosystem
> Affects Versions: 1.13.0
> Reporter: Kezhu Wang
> Priority: Major
>
> Currently, there are multiple places to establish jdbc connection, several of
> them were written before introducing of {{JdbcConnectionProvider}} in
> FLINK-15782. We need to migrate these classes for reasons:
> * Code reusability.
> * Circumvent pitfalls of {{DriverManager}} such as FLINK-19435 and possible
> [others|https://ci.apache.org/projects/tomcat/tomcat85/docs/jndi-datasource-examples-howto.html#DriverManager,_the_service_provider_mechanism_and_memory_leaks]
> in one place.
