Phil Zampino created KNOX-1107:
Summary: Remote Configuration Registry Client Service
Project: Apache Knox
Issue Type: Bug
Affects Versions: 0.15.0
Reporter: Phil Zampino
Assignee: Phil Zampino
There are currently multiple ZooKeeper clients in Knox, in the form of HA
provider URL managers.
These clients has been added to Knox independently, each without concern for
the other. KNOX-1010 introduces yet another such client.
In order to manage the configuration of these clients, it would be good to have
a Client Service, from which these features can retrieve a ZooKeeper client.
Furthermore, in the future, Knox may support additional configuration
registries (e.g., consul, etcd), which these features may wish to employ. If
this service is abstracted sufficiently, the underlying registry type can be a
simple configuration change.
In addition to managing security configuration for these clients, the service
may also be able to enforce some ACL constraints on referenced znodes (or other
registry entries) to mitigate the consumption of untrusted configuration.
