本文整理了Java中org.apache.hadoop.hbase.replication.ZKReplicationPeerStorage类的一些代码示例，展示了ZKReplicationPeerStorage类的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。ZKReplicationPeerStorage类的具体详情如下：
包路径：org.apache.hadoop.hbase.replication.ZKReplicationPeerStorage
类名称：ZKReplicationPeerStorage

ZKReplicationPeerStorage介绍

[英]ZK based replication peer storage.
[中]基于ZK的复制对等存储。

代码示例

/**
 * Create a new {@link ReplicationPeerStorage}.
 */
public static ReplicationPeerStorage getReplicationPeerStorage(ZKWatcher zk, Configuration conf) {
 return new ZKReplicationPeerStorage(zk, conf);
