  17. queues within queues - a feature called hierarchical queues. All queues are
  18. defined within the 'queues' tag which is the top level element for this
  19. XML document. The queue acls configured here for different queues are
  20. checked for authorization only if the configuration property
  21. mapreduce.cluster.acls.enabled is set to true. -->

  35. If set to '*', it allows all users to submit jobs to the queue.
  36. If set to ' '(i.e. space), no user will be allowed to do this
  37. operation. The default value for any queue acl is ' '.
  38. For specifying a list of users and groups the format to use is
  39. user1,user2 group1,group2
  40. It is only used if authorization is enabled in Map/Reduce by setting
  41. the configuration property mapreduce.cluster.acls.enabled to true.

  43. cluster and cluster administrators configured via
