Hi Devs
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 isTableEnaled() 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 () ]. I think this will be an
issue.
