    Details

      Description

      service check failing for some services if custom capacity scheduler is enabled with out default queue.

      Configure mydefault queue instead of default queue like below in YARN config.

      yarn.scheduler.capacity.root.queues=mydefault
      yarn.scheduler.capacity.root.mydefault.user-limit-factor=1
      yarn.scheduler.capacity.root.mydefault.state=RUNNING
      yarn.scheduler.capacity.root.mydefault.maximum-capacity=100
      yarn.scheduler.capacity.root.mydefault.capacity=100
      yarn.scheduler.capacity.root.mydefault.acl_administer_jobs=*
      yarn.scheduler.capacity.root.default.acl_submit_applications=*
      yarn.scheduler.capacity.root.capacity=100
      yarn.scheduler.capacity.root.acl_administer_queue=*
      yarn.scheduler.capacity.root.accessible-node-labels=*
      yarn.scheduler.capacity.node-locality-delay=40
      yarn.scheduler.capacity.mydefault.minimum-user-limit-percent=100
      yarn.scheduler.capacity.maximum-applications=10000
      yarn.scheduler.capacity.maximum-am-resource-percent=0.2

      and restart affected components.

      Run service check for oozie. You will see that fail.

      We need to maintain default queue just to test service check for some services.

      I can not have different name for my default queue. I have to allocate some resources for default queue for the sake of service checks.
