   > Now, yarn queue can only be associate to tenant(租户),the tenant is a hadoop 
user in a hadoop cluster .
   > The yarn queue must be real and the hadoop user must have permission to 
submit jobs to the yarn queue.
   > Therefore, I think, if possible, the yarn queue that can be selected when 
creating the mr task must be the yarn queue associated with the tenant 
corresponding to the user.

   > In addition, the current tenant and yarn queue have a one-to-one 
relationship. So, it is meaningless to let users choose yarn queue. If a tenant 
can associate multiple yarn queues, it is a good idea to let users choose yarn 
queue when creating mr tasks.
   
   ----------------------------------
   
   In most of the yarn clusters, multi queue is used
   
   Now, a user can only use one queue, if you want to use other queues, there 
is no way
   
   It is very common that a user can use multiple queues, so this pr .
