有没有办法从命令行获取所有可用YARN队列的列表,而无需求助于解析capacity-scheduler.xml
文件?
我正在使用Hadoop 2.7.2版
一种方法是使用ResourceManager REST API,例如:
curl '<resourcemanager_host>:<http_port>/ws/v1/cluster/scheduler' | jq '.scheduler.schedulerInfo.queues.queue[] | .queueName’
将列出所有顶级队列。
curl '<resourcemanager_host>:<http_port>/ws/v1/cluster/scheduler' | jq .
为您提供有关调度程序/队列的所有信息,因此使用jq
您可以从中获取任何信息。
您也可以使用mapred
命令行工具
[email protected]$ mapred queue -list
======================
Queue Name : root.tenant1
Queue State : running
Scheduling Info : Capacity: 0.0, MaximumCapacity: UNDEFINED, CurrentCapacity: 0.0
======================
Queue Name : root.tenant1.default
Queue State : running
Scheduling Info : Capacity: 0.0, MaximumCapacity: UNDEFINED, CurrentCapacity: 0.0
======================
Queue Name : root.tenant1.users
Queue State : running
Scheduling Info : Capacity: 0.0, MaximumCapacity: UNDEFINED, CurrentCapacity: 0.0
======================
Queue Name : root.tenant2
Queue State : running
Scheduling Info : Capacity: 0.0, MaximumCapacity: UNDEFINED, CurrentCapacity: 0.0
======================
Queue Name : root.tenant2.default
Queue State : running
Scheduling Info : Capacity: 0.0, MaximumCapacity: UNDEFINED, CurrentCapacity: 0.0
======================
Queue Name : root.tenant2.users
Queue State : running
Scheduling Info : Capacity: 0.0, MaximumCapacity: UNDEFINED, CurrentCapacity: 0.0
======================
它提供了一个很好的输出与层次结构
