Hadoop YARN: Get a list of available queues

Is there a way to get a list of all available YARN queues from the command line, without resorting to parsing the capacity-scheduler.xml file?

I'm using Hadoop version 2.7.2

Solution

  • One way is to use ResourceManager REST API, for example:

    curl '<resourcemanager_host>:<http_port>/ws/v1/cluster/scheduler' | jq '.scheduler.schedulerInfo.queues.queue[] | .queueName’

    will list all top level queues.

    curl '<resourcemanager_host>:<http_port>/ws/v1/cluster/scheduler' | jq .

    gives you all kind of information about scheduler/queues, thus using jq you can get any information out of it.
