Description

There are many user cases that one user owns many queues in his organization's cluster for different business usages in practice. These queues often share the same properties, such as minimum-user-limit-percent and user-limit-factor. Users have to write one property for every queue they use if they want to use customized these shared properties. Adding default queue properties for these cases will simplify capacity scheduler's configuration file and make it easy to adjust queue's common properties. 
 
  CHANGES:

Add two properties as queue's default value in capacity scheduler's configuration:

• yarn.scheduler.capacity.minimum-user-limit-percent
• yarn.scheduler.capacity.user-limit-factor
