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.
