从接口复制的说明: ReplicationQueuesClient

Get a list of all region servers that have outstanding replication queues. These servers could be alive, dead or from a previous run of the cluster.

指定者:

getListOfReplicators 在接口中 ReplicationQueuesClient

返回:

a list of server names

抛出:

org.apache.zookeeper.KeeperException - zookeeper exception

getLogsInQueue

public List<String> getLogsInQueue(String serverName,
                          String queueId)
                            throws org.apache.zookeeper.KeeperException

从接口复制的说明: ReplicationQueuesClient

Get a list of all WALs in the given queue on the given region server.

指定者:
