[kgf@hadoop21 hadoop-3.1.3]$

3.2、打印ApplicationAttemp状态：yarn applicationattempt -status <ApplicationAttemptId>

[kgf@hadoop21 hadoop-3.1.3]$ yarn applicationattempt -status appattempt_1655215095011_0001_000001
2022-06-14 14:41:30,992 INFO client.RMProxy: Connecting to ResourceManager at hadoop21/192.168.56.21:8032

4、yarn container查看容器

4.1、列出所有Container：yarn container -list <ApplicationAttemptId>

[kgf@hadoop21 hadoop-3.1.3]$ yarn container -list appattempt_1655215095011_0001_000001
2022-06-14 14:45:20,569 INFO client.RMProxy: Connecting to ResourceManager at hadoop21/192.168.56.21:8032
Total number of containers :0
                  Container-Id            Start Time             Finish Time                   State                    Host       Node Http Address                                LOG-URL
[kgf@hadoop21 hadoop-3.1.3]$

4.2、打印Container状态： yarn container -status <ContainerId>

[atguigu@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

5.1、列出所有节点：yarn node -list -all

[kgf@hadoop21 hadoop-3.1.3]$ yarn node -list -all
2022-06-14 14:47:23,197 INFO client.RMProxy: Connecting to ResourceManager at hadoop21/192.168.56.21:8032
Total Nodes:3
         Node-Id             Node-State Node-Http-Address       Number-of-Running-Containers

[kgf@hadoop21 hadoop-3.1.3]$

6、yarn queue查看队列

打印队列信息：yarn queue -status <QueueName>

[kgf@hadoop21 hadoop-3.1.3]$ yarn queue -status default
2022-06-14 14:48:36,392 INFO client.RMProxy: Connecting to ResourceManager at hadoop21/192.168.56.21:8032
Queue Information :
