### Search before asking - [X] I had searched in the [issues](https://github.com/apache/doris/issues?q=is%3Aissue) and found no similar issues. ### Version 2.1.0-rc11 ### What's Wrong? There are two reasons lead to this bug: <br /> 1. The package name of the `AuditEvent` class has been changed from `org.apache.doris.plugin` to `org.apache.doris.plugin.audit`, when worker in `AuditEventProcessor` pass audit event to the old external audit loader plugin, it causes `AbstractMethodError` due to method signature mismatched, and this also makes worker thread down. <br /> 2. The package name of the built-in `AuditLoaderPlugin` class is same with the external one, when try to use `DynamicPluginLoader` to load the external audit loader plugin, it always loads the built-in one due to parent delegation model mechanism. <br /> Code location: org.apache.doris.plugin.audit.AuditEvent ```java package org.apache.doris.plugin.audit; ``` <br /> org.apache.doris.qe.AuditEventProcessor ```java public class Worker implements Runnable { @Override public void run() { ... for (Plugin plugin : auditPlugins) { if (((AuditPlugin) plugin).eventFilter(auditEvent.type)) { ((AuditPlugin) plugin).exec(auditEvent); } } ... } } ``` <br /> org.apache.doris.plugin.DynamicPluginLoader ```java Plugin dynamicLoadPlugin(boolean closePreviousPlugin) throws IOException, UserException { ... ClassLoader parentLoader = PluginClassLoader.createLoader(getClass().getClassLoader(), Collections.EMPTY_LIST); ClassLoader loader = URLClassLoader.newInstance(jarList.toArray(new URL[0]), parentLoader); Class<? extends Plugin> pluginClass; try { pluginClass = loader.loadClass(pluginInfo.getClassName()).asSubclass(Plugin.class); } catch (ClassNotFoundException e) { throw new UserException("Could not find plugin class [" + pluginInfo.getClassName() + "]", e); } ... } ``` ### What You Expected? the external audit loader plugin can still work after upgrading ### How to Reproduce? install audit loader plugin before 2.1.0, then upgrade to 2.1.0 ### Anything Else? I'd like to submit a PR to add `.ext` in the end of package name of external audit loader plugin, so that it can be loaded by class loader ### Are you willing to submit PR? - [X] Yes I am willing to submit a PR! ### Code of Conduct - [X] I agree to follow this project's [Code of Conduct](https://www.apache.org/foundation/policies/conduct) -- This is an automated message from the Apache Git Service.
