我无法在分布式模式下设置 hbase。当我在一台机器上设置它时它工作正常（独立模式）。我的 Zookeeper、hmaster 和区域服务器正常启动。
但是当我去 hbase shell 并查找状态时。它向我显示 0 区域服务器。我正在附加我的区域服务器日志。加上我的主（namenode）和从属（datanode）的主机文件。我已经尝试了 stackoverflow 上提供的用于更改主机文件的所有 P&C，但对我不起作用。

从 hosts 文件中删除 127.0.1.1 并关闭 IPV6。那应该可以解决问题。

您的 Regionserver 正在 naresh-pc 上寻找 HMaster，但您的 /etc/hosts 文件中没有任何此类条目。请确保您的配置正确。

您可以尝试所有这些吗：

确保您的/conf/regionservers文件只有一个条目：slave

不确定您使用的是什么 HBase 版本，但不要在 hbase-site.xml中使用端口54310作为属性，而是使用端口hbase.rootdir9000

您的 /etc/hosts 文件，在主服务器和从服务器上应该只包含这些自定义条目：

127.0.0.1 本地主机
192.168.0.108 主机
192.168.0.126 从机

我担心您的日志状态Opening socket connection to server naresh-pc/192.168.0.108:2181

显然系统认为 zookeeper 在 host 上naresh-pc，但是在您的配置中，您将 zookeeper quorum 设置在 hostmaster上，HBase 将绑定到它。这是一个问题。根据我的经验，HBase 对主机名非常挑剔，因此请确保它们在所有配置和 /etc/hosts 文件中都同步。

此外，这可能是一个小问题，但在 .xml 文件中指定 zookeper 数据目录以具有应该使集群工作的最小设置集不会有什么坏处：hbase.zookeeper.property.dataDir
