Robert Kanter commented on YARN-1877:
-------------------------------------

Discussed with Karthik offline.  There's no need to add an additional property 
for the auth for the root node as all auths are added the same way to the 
ZooKeeper client (i.e. it's not for a specific node; only the ACLs are) and we 
already have {{yarn.resourcemanager.zk-auth}} which can be used for passing in 
a list of auths.  

However, {{yarn.resourcemanager.zk-auth}} is not documented in 
yarn-default.xml, so we can repurpose this JIRA to document this property, 
including the fact that it accepts auths for both 
{{yarn.resourcemanager.zk-acl}} and 
{{yarn.resourcemanager.zk-state-store.root-node.acl}}.

> ZK store: Add yarn.resourcemanager.zk-state-store.root-node.auth for root 
> node auth
