Shen Yinjie updated YARN-6462:
------------------------------
    Description: 
we need a yarn command to list all leaf queues.

especially in large scale cluster ,there are a large amount of  queues in 
tree-format for various apps , we actually need a list-all-leaf-queues 
interface to get queues infomation immediately ,other than search in fair 
scheduler.xml or in yarn-scheduler web layer by layer.sometimes we should also 
vertify a new queue is successfully added in scheduer, instead of fail for some 
format error or other wise.

  was:we need a yarn command to list all leaf queues.
