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
2023-05-30 03:19:35,136 INFO org.apache.flink.runtime.resourcemanager.active.ActiveResourceManager [] - Registering TaskManager with ResourceID container_e03_1684463979345_0028_01_000003(hadoop03:45454) (akka.tcp://flink@hadoop03:43225/user/rpc/taskmanager_0) at ResourceManager 2023-05-30 03:19:35,147 INFO org.apache.flink.runtime.resourcemanager.active.ActiveResourceManager [] - Worker container_e03_1684463979345_0028_01_000003(hadoop03:45454) is registered.

taskmanager容器名：container_e03_1684463979345_0028_01_000003
taskmangerIp: hadoop03

http://hadoop02:19888/jobhistory/logs/{taskmangerIp}:45454/{taskmanager的容器名}/{taskmanager的容器名}/root
注意：应该会有好多个taskmanger
