Hbase复制不复制数据

我有2个名为A和B的hbase集群,每个集群有3台机器,我想在2集群之间启用复制,这里是步骤

将配置添加到 hbase-site.xml

<property>
    <name>hbase.replication</name>
    <value>true</value>
</property>

在主群集A中,添加对等

add_peer '2',"wxmaster1,wxmaster2,wxslave1:2181:/hbase2"

这个返回成功,正如我在日志中看到的那样,集群主日志已经初始化了与集群B区域服务器的会话连接。

在群集A和B中创建相同的表

create 'test_replication', {NAME => 'cf', REPLICATION_SCOPE => '1', VERSIONS => '2', KEEP_DELETED_CELLS => 'TRUE'}

然后我认为一切都应该没问题,集群A表的任何变化&#39; test_replication&#39;将复制到集群B,而不是,并且没有任何错误日志。

以下是status 'replication'的结果 enter image description here

任何人都可以帮助我吗?

而且,我正在使用

Hadoop的2.5.2
HBase的-1.0.1
动物园管理员-3.4.6

答案 0 :(得分:0)

finnaly我解决了这个问题,由于我的add_peer命令错误,znode不存在,应该是

add_peer&#39; 2&#39;,&#34; wxmaster1,wxmaster2,wxslave1:2181:/ hbase&#34;
