Flink on yarn任务日志怎么看

1、jobmanager日志

    在yarn上可以直接看

2、taskmanager日志

     在flink的webui中可以看，但是flink任务失败后，webui就不存在了，那怎么看？

这是jobmanager的地址

hadoop02:19888/jobhistory/logs/hadoop02:45454/container_e03_1684463979345_0028_01_000001/container_e03_1684463979345_0028_01_000001/root

然你要看taskmanager的地址，首先我们要知道taskmanager运行在

打开Jobmanager日志

全局搜索

 Registering TaskManager with ResourceID 

后边就是taskmanager地址因此，替换一下url就可以得到这个taskmanger的地址

taskmanager容器名：container_e03_1684463979345_0028_01_000003

taskmangerIp: hadoop03

注意：应该会有好多个taskmanger
