> In case of secure cluster, we allow the HBase clients to read the zk nodes by
> providing the global read permissions to all for certain nodes. These nodes
> are the master address znode, root server znode and the clusterId znode. In
> ZKUtil.createACL() , we can see these node names are specially handled.
> But there are some other client side admin APIs which makes a read call into
> the zookeeper from the client. This include the isTableEnabled() call (May be
> some other. I have seen this). Here the client directly reads a node in the
> zookeeper ( node created for this table ) and the data is matched to know
> whether this is enabled or not.
> Now in secure cluster case any client can read zookeeper nodes which it needs
> for its normal operation like the master address and root server address.
> But what if the client calls this API? [isTableEnaled () ].
