> Extend PluginLoader to allow closing of backing ClassLoader
> -----------------------------------------------------------
>
> Key: FLINK-23029
> URL: https://issues.apache.org/jira/browse/FLINK-23029
> Project: Flink
> Issue Type: Improvement
> Components: Runtime / Coordination
> Reporter: Chesnay Schepler
> Assignee: Chesnay Schepler
> Priority: Major
> Labels: pull-request-available
> Fix For: 1.14.0
>
>
> The PluginLoader is currently never closing the backing classloader, which
> means that plugins remain loaded until the application shuts down.
> This for example makes it impossible to use the plugins in the mini cluster
> IT cases, because they would be loaded multiple times, eventually failing
> with an OOM.
