在我的设置中，由于电源中断，我的VM在重新启动所有虚拟机后都处于关闭状态 我无法启动Hbase，所有其他服务可以重新启动/停止/启动但在UI中用于CM 在hbase ACTIONS选项卡中，所有选项都被隐藏了..
以下是我的hbase主日志，现在处于退出模式

感谢您的关注......

从日志中我们可以看到它无法连接ZooKeeper服务器。您可能需要启动ZooKeeper服务并尝试重新启动HBase
答案 1 :(得分：0)
正如zhutoulala之前所说，我也会建议，如果它仍然不起作用，你应该删除HBase的znode：
使用运行HBase服务的其中一台服务器上的'hbase zkcli'命令。进入ZooKeeper CLI后，您可以运行'rmr / hbase'来删除znode。
