【问题描述】:
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 个集群之间启用复制,这是步骤
将配置添加到 hbase-site.xml
<property>
<name>hbase.replication</name>
<value>true</value>
</property>
在master集群A中,添加peer
add_peer '2',"wxmaster1,wxmaster2,wxslave1:2181:/hbase2"
这返回成功,正如我在日志中看到的那样,集群 A 主日志已初始化到集群 B 区域服务器的会话连接。
在集群 A 和 B 中创建同一张表
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 'test_replication' 的任何更改都会复制到集群 B,而它不会,并且没有任何错误日志。

有人可以帮助我吗?
而且,我正在使用
hadoop-2.5.2
hbase-1.0.1
zookeeper-3.4.6
