Hbase:此服务器在失败的服务器列表中:localhost/127.0.0.1:38812

Question

我正在尝试连接到远程 HBase 服务器。远程服务器在 Ubuntu 上运行并且运行良好并且能够使用 Hbase 客户端(shell)以及 Java 客户端访问它。但是，当我尝试使用相同的 Java 客户端从 Windows 机器连接到该服务器时

 org.apache.hadoop.conf.Configuration hadoopConf = HBaseConfiguration.create();
 hadoopConf.set("hbase.zookeeper.quorum", "Paras-Lenovo");

出现以下错误:

请注意，窗口主机文件中的条目没有问题，我能够从 Windows 机器远程登录 hbase/zookeper 端口的 60010 和 2181 端口，所以问题不是因为连接。问题Hbase client do not able to connect with remote Hbase server与此类似，但这也没有解决问题。

今天在客户端远程访问hbase时出现了同样的错误，终于解决了。只是为了他人的利益而发布解决方法。

我在远程系统中用于 hbase java 客户端的库与 hadoop 系统中的库不同。一旦我使用了同一组库，问题就解决了。
