             Summary: Make the default-application-priority attribute of queues 
globally configurable
                 Key: YARN-11858
                 URL: https://issues.apache.org/jira/browse/YARN-11858
             Project: Hadoop YARN
          Issue Type: Improvement
    Affects Versions: 3.4.2, 3.4.1, 3.3.6, 3.3.3
            Reporter: wangzhongwei
            Assignee: wangzhongwei


 Currently, if the yarn.cluster.max-application-priority is set to 10, and we 
want the default application priority of queues to be configured as 5—allowing 
tasks to lower their application priority if they are less important or raise 
it if they are more important—the current behavior is that if the 
default-application-priority of a queue is not explicitly set, it defaults to 
0. To achieve the desired effect, each queue must be individually set to 5, 
which is cumbersome. There is a need for a global default configuration that 
sets this value to 5.
