This JIRA extends > the ActiveStandbyElector which adds an extra non-ephemeral node into the ZK > directory, which acts as a second copy of the active node's information. > Then, if the active loses its ZK session, the next active to be elected may > easily locate the unfenced node to take the appropriate actions. -- This message is automatically generated by JIRA.
