Yin Zhi Qiang updated YARN-3173:
--------------------------------
    Description: When configuration more than one RM, for example in the HA 
cluster, using the start-yarn.sh script to start yarn cluster,but the cluster 
only start up with one resourcemanager  on the node which start-yarn.sh be 
executed. I think yarn should sense how many RMs been configured at the 
beginning, and start them all in start-yarn.sh script.  (was: When config more
