java - HBase 连接拒绝

转载作者：可可西里更新时间：2023-11-01 14:29:44

您好，我正在使用 hadoop 和 HBase。当我尝试启动 hadoop 时，它启动正常，但是当我尝试启动 HBase 时，它在日志文件中显示异常。在日志文件中，hadoop 拒绝本地主机端口 54310 上的连接。日志如下:

最佳答案

试试这个

使用 # 在/etc/hosts 文件中注释 127.0.1.1然后将您的 ip 和计算机名称放在新行中如果你想使用 localhost 确保 127.0.0.1 localhost 在你的主机文件中然后将配置文件中所有出现的 ip 替换为 localhost

如果您想使用 ip 而不是 localhost，请确保 ip 和等效域名存在于您的主机文件中，并将所有出现的 localhost 替换为您的 ip。

与namenode相关的问题一般是由于主机或IP配置错误导致
