无法连接到远程服务器使用Hbase

Question

无法连接到远程服务器使用Hbase

4

我对Hadoop和Hbase非常陌生。我正在尝试使用Java代码创建一个表并连接到我的远程服务器(Hbase)，该服务器的IP地址是172.80.72.86。它是一台Linux机器(172.80.72.86)。我尝试了以上操作，但是遇到了以下错误：

更好的方法是加载您的配置文件，而不是手动设置。

当出现错误“服务器null的Session 0x0”时，可能的一个问题是您的HBase代码不知道要连接到哪里。解决此问题的最佳方法是加载您的hbase-site.xml配置文件。

Configuration config = HBaseConfiguration.create();
config.addResource(new Path("/XXXX/hbase/hbase-0.98.9/conf/hbase-site.xml"));

指定zookeeper的IP并继续。客户端电脑必须知道zookeeper正在运行的位置。
在您的程序中，将以下行附加到配置旁边。

config.set("hbase.zookeeper.quorum", "172.80.72.86");  // Your remote Pc where the zookeeper is running. Mention the port if needed."172.80.72.86:60020"

- Balaji

你在哪个操作系统上配置了Hbase？你是否进行了SSH连接？ - Balaji

删除此并重新启动HBase。 <property> <name>hbase.zookeeper.property.clientPort</name> <value>60020</value> </property> - Balaji

Linux机器，我的Hadoop已安装，删除后仍然出现相同的错误。 - Navyah
