<>一、 yarn常用命令:

<>1.yarn application 查看任务

(1)列出所有Application

yarn application -list
(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)

<>2.yarn logs 查看日志

(1)查看Application 日志

yarn logs -applicationId

(2)查询Container 日志
yarn logs -applicationId -containerId

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

<>4. yarn container查看容器

(1)列出所有 Container yarn container -list ApplicationAttemptId>
(2)打印 Container 状态
yarn container -status ContainerId>

<>5.yarn node 查看节点状态

列出所有节点
yarn node -list -all

<>6.yarn rmadmin 跟新配置

yarn rmadmin -refreshQueues

<>7.yarn queue 查看队列

打印队列信息
yarn queue -status

<>二、常用命令汇总

<>1. yarn 命令行查看资源状态:

yarn top

<>2.查看指定queue使用情况:

yarn queue -status root.user.xxxx
示例: yarn queue -status root.j042x0

<>3.查看app状态:

yarn application -list -appStates 、 yarn application -list -appTypes

<>4.移动app到对应的队列:

示例:yarn application -movetoqueue application_1528080031923_0067 -queue
root.j042x0

<>5.kill掉某个app任务:
yarn application -kill applicationId 例如:要杀掉这个任务:yarn application -kill
application_1528080031923_0067
<>6.查看Application 日志:
yarn logs -applicationId 示例:yarn logs -applicationId
application_1528080031923_0064
<>7.查看app状态命令:

yarn applicationattempt -list applicationId

<>8.打印类路径:

yarn classpath --glob

<>9. 打印正在执行任务的容器信息:

yarn container -list appattemptId
示例:yarn container -list appattempt_1528080031923_0068_000001

<>10.打印当前容器信息:

yarn container -status containerId

<>11. 提交任务到yarn:

yarn jar [mainClass] args…

<>12. 查看yarn集群所有节点信息:

yarn node -all -list

<>13. yarn application -list 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)
示例:yarn application -list -appStates RUNNING 查看正在运行的应用的状态信息
