> Web service authentication uses the yarn resourcemanager proxy initially to 
> deliver a security token. It needs to know the address of the proxy so that 
> it can verify that the initial request came from a legitimate source. To do 
> this it gets the address from the yarn.resourcemanager.webapps.address.<rmId> 
> property in HA scenarios. Sometimes this property is absent and only 
> yarn.resourcemanager.hostname.<rmId> is persent. In these scenarios use this 
> property to get the address.
