- 使用注意:
- yarn任务会默认分配给production队列。
- 开发时可以指定任务运行队列
- 集群组件队列参数设置
- yarn 容量调度器参数说明和示例
- yarn.scheduler.capacity.default.minimum-user-limit-percent=1 每个任务占用的最少资源
- yarn.scheduler.capacity.maximum-am-resource-percent=0.2 设置有多少资源可以用来运行app master,即控制当前激活状态的应用。默认是10%。
- yarn.scheduler.capacity.maximum-applications=10000 设置系统中可以同时运行和等待的应用数量。默认是10000.
- yarn.scheduler.capacity.node-locality-delay=40 调度器尝试进行调度的次数。一般都是跟集群的节点数量有关。默认40(一个机架上的节点数)
- yarn.scheduler.capacity.resource-calculator=org.apache.hadoop.yarn.util.resource.DefaultResourceCalculator 资源计算方法,默认是
- yarn.scheduler.capacity.root.accessible-node-labels=*
- yarn.scheduler.capacity.root.acl_administer_queue=* 哪些用户或用户组可以管理队列
- yarn.scheduler.capacity.root.acl_submit_applications=* 访问控制列表ACL控制谁可以向该队列提交任务。如果一个用户可以向该队列提交,那么也可以提交任务到它的子队列
- yarn.scheduler.capacity.root.capacity=100 一个百分比的值,表示占用整个集群的百分之多少比例的资源,这个queue-path下所有的capacity之和是100
- yarn.scheduler.capacity.root.queues=default,workflow
- yarn.scheduler.capacity.root.default.acl_administer_jobs=* 哪些用户或用户组可以管理队列
- yarn.scheduler.capacity.root.default.acl_submit_applications=* 哪些用户或用户组可以提交人物
- yarn.scheduler.capacity.root.default.capacity=20 一个百分比的值,表示占用整个集群的百分之多少比例的资源,这个queue-path下所有的capacity之和是100
- yarn.scheduler.capacity.root.default.maximum-capacity=100 弹性设置,最大时占用多少比例资源
- yarn.scheduler.capacity.root.default.state=RUNNING 队列状态,可以是RUNNING或STOPPED
- yarn.scheduler.capacity.root.default.user-limit-factor=1 每个用户的低保百分比,比如设置为1,则表示无论有多少用户在跑任务,每个用户占用资源最低不会少于1%的资源
- yarn.scheduler.capacity.root.workflow.acl_administer_jobs=* 哪些用户或用户组可以管理队列
- yarn.scheduler.capacity.root.workflow.acl_submit_applications=* 哪些用户或用户组可以提交人物
- yarn.scheduler.capacity.root.workflow.capacity=80 一个百分比的值,表示占用整个集群的百分之多少比例的资源,这个queue-path下所有的capacity之和是100
