> After YARN-2656, if people set hadoop.proxyuser for the client<-->RM RPC
> interface, it's not going to work, because ProxyUsers#sip is a singleton per
> daemon. After YARN-2656, RM has both channels that want to set this
> configuration: RPC and HTTP. RPC interface sets it first by reading
> hadoop.proxyuser, but it is overwritten by HTTP interface, who sets it to
> empty because yarn.resourcemanager.webapp.proxyuser doesn't exist.
> The fix for it could be similar to what we've done for YARN-2676: make the
> HTTP interface anyway source hadoop.proxyuser first, then
> yarn.resourcemanager.webapp.proxyuser.
