Karthik Kambatla commented on YARN-1573:
----------------------------------------
The private password is only for create-delete perms. The admin still has admin
access and can reclaim all other kinds of accesses as well.
> ZK store should pick a private password for root-node-acls

> Currently, when HA is enabled, ZK store uses cluster-timestamp as the
> password for root node ACLs to give the Active RM exclusive access to the
> store. A more private value like a random number might be better.
