我有一个名称节点，其fsimage损坏了，并且目录中只有一个fsimage可用。我想从命令“ hdfs namenode -recover”中恢复它。但是，出现以下错误。

我试图使节点退出安全模式，但它不起作用，并出现以下错误
./ hdfs dfsadmin -safemode离开 安全模式：由于发生连接异常而从rakeshbharadwaj-VirtualBox / 127.0.1.1到localhost：9001的调用失败：java.net.ConnectException：连接被拒绝；有关更多详细信息，请参见：http://wiki.apache.org/hadoop/ConnectionRefused
询问：我需要恢复fsimage并启动namenode的帮助。
