> 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.
