   Agree with @zentol to have a separate pattern config for plugins and exclude hadoop from it. A plugin should never rely on specific libraries (i.e. hadoop) in the system classloader. @pnowojski also proposed it in the [JIRA FLINK-15355](https://issues.apache.org/jira/browse/FLINK-15355?focusedCommentId=17006836&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-17006836).
   
   @wangyang0918 I think each plugin can use `PluginDescriptor#loaderExcludePatterns` to specify classes to load from parent first (though not ready yet, see `DirectoryBasedPluginFinder#createPluginDescriptorForSubDirectory`). It could be an optional file for each plugin.
