flink版本1.13.6
1. 问题
flink 任务运行在yarn集群,plugins加载失效,导致通过扩展资源获取任务参数失效
2. 问题定位 yarn容器的jar包及插件信息,jar包是正常上传 源码定位 加载plugins入口TaskManagerRunner.class PluginUtils.createPluginManagerFromRootFolder 源码加载扩展资源参数入口TaskManagerRunner.class ExternalResourceUtils.createStaticExternalResourceInfoProviderFromConfig 日志信息 定位PluginConfig源码
3. 方案
重写覆盖集群的PluginConfig.java,优先从configurtaion获取
