Allow dynamic addition/removal of server nodes in the client API ----------------------------------------------------------------
Key: ZOOKEEPER-762 URL: https://issues.apache.org/jira/browse/ZOOKEEPER-762 Project: Zookeeper Issue Type: Sub-task Components: c client, java client Reporter: Dave Wright Priority: Minor Currently the list of zookeeper servers needs to be provided to the client APIs at construction time, and cannot be changed without a complete shutdown/restart of the client API. However, there are scenarios that require the server list to be updated, such as removal or addition of a ZK cluster node, and it would be nice if the list could be updated via a simple API call. The general approach (in the Java client) would be to "RemoveServer()/AddServer()" functions for Zookeeper that calls down to ClientCnxn, where they are just maintained in a list. Of course if the server being removed is the one currently connected, we'd need to disconnect, but a simple call to disconnect() seems like it would resolve that and trigger the automatic re-connection logic. An equivalent change could be made in the C code. This change would also make dynamic cluster membership in ZOOKEEPER-107 easier to implement. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
