                Application-Id     Application-Name     Application-Type       User      Queue              State        Final-State        Progress                        Tracking-URL

（2）根据Application状态过滤：yarn application -list -appStates （所有状态：ALL、NEW、NEW_SAVING、SUBMITTED、ACCEPTED、RUNNING、FINISHED、FAILED、KILLED）

[hadoop102 hadoop-3.1.3]$ yarn application -list -appStates FINISHED

2024-02-06 10:22:20,029 INFO client.RMProxy: Connecting to ResourceManager at hadoop103/192.168.10.103:8032

2024-02-06 10:23:48,530 INFO client.RMProxy: Connecting to ResourceManager at hadoop103/192.168.10.103:8032

Application application_1612577921195_0001 has already finished

 

2、 yarn logs查看日志

（1）查询Application日志：yarn logs -applicationId <ApplicationId>

[hadoop102 hadoop-3.1.3]$ yarn logs -applicationId application_1612577921195_0001

（2）查询Container日志：yarn logs -applicationId <ApplicationId> -containerId <ContainerId>

[hadoop102 hadoop-3.1.3]$ yarn logs -applicationId application_1612577921195_0001 -containerId container_1612577921195_0001_01_000001

 

3、 yarn applicationattempt查看尝试运行的任务

（1）列出所有Application尝试的列表：yarn applicationattempt -list <ApplicationId>

[hadoop102 hadoop-3.1.3]$ yarn applicationattempt -list application_1612577921195_0001

2024-02-06 10:26:54,195 INFO client.RMProxy: Connecting to ResourceManager at hadoop103/192.168.10.103:8032

Total number of application attempts :1

         ApplicationAttempt-Id                State                     AM-Container-Id                        Tracking-URL

appattempt_1612577921195_0001_000001             FINISHED container_1612577921195_0001_01_000001hadoop103:8088/proxy/application_1612577921195_0001/

（2）打印ApplicationAttemp状态：yarn applicationattempt -status <ApplicationAttemptId>

[hadoop102 hadoop-3.1.3]$ yarn applicationattempt -status appattempt_1612577921195_0001_000001

2024-02-06 10:27:55,896 INFO client.RMProxy: Connecting to ResourceManager at hadoop103/192.168.10.103:8032

Application Attempt Report :

4、 yarn container查看容器

（1）列出所有Container：yarn container -list <ApplicationAttemptId>

[hadoop102 hadoop-3.1.3]$ yarn container -list appattempt_1612577921195_0001_000001

2024-02-06 10:28:41,396 INFO client.RMProxy: Connecting to ResourceManager at hadoop103/192.168.10.103:8032

Total number of containers :0

                  Container-Id           Start Time          Finish Time                State                 Host    Node Address

（2）打印Container状态： yarn container -status <ContainerId>

[hadoop102 hadoop-3.1.3]$ yarn container -status container_1612577921195_0001_01_000001

2021-02-06 10:29:58,554 INFO client.RMProxy: Connecting to ResourceManager at hadoop103/192.168.10.103:8032

Container with id 'container_1612577921195_0001_01_000001' doesn't exist in RM or Timeline Server.

    注：只有在任务跑的途中才能看到container的状态

 

5、 yarn node查看节点状态

列出所有节点：yarn node -list -all

[hadoop102 hadoop-3.1.3]$ yarn node -list -all

 hadoop104:39702         RUNNING    hadoop104:8042                            0

6、 yarn rmadmin更新配置

加载队列配置：yarn rmadmin -refreshQueues

[hadoop102 hadoop-3.1.3]$ yarn rmadmin -refreshQueues

2024-02-06 10:32:03,331 INFO client.RMProxy: Connecting to ResourceManager at hadoop103/192.168.10.103:8033

7、 yarn queue查看队列
