> RM fail with noAuth error if switched from non-failover mode to failover mode

> The scenario is that RM failover was initially enabled, so the zkRootNodeAcl is by default set with the *RM ID* in the ACL string
> If RM failover is then switched to be disabled, it cannot load data from ZK and fail with noAuth error. After I reset the root node ACL, it again can access.

> the problem may be that in non-failover mode, RM doesn't use the *RM-ID* to connect with ZK and thus fail with no Auth error.
> We should be able to switch failover on and off with no interruption to the user.
