namenode格式期间的Hadoop单节点集群设置错误答案

【问题标题】：Hadoop Single Node Cluster setup error during namenode formatnamenode格式期间的Hadoop单节点集群设置错误
【发布时间】：2018-12-26 14:13:41
【问题描述】：

我已在 Windows 10 中安装了 Apache Hadoop 2.6.0。我一直在尝试解决此问题，但未能理解错误或我的任何错误。

我已正确设置所有路径，Hadoop 版本在命令提示符中正确显示版本。

我已经在 hadoop 目录中创建了temp 目录，例如c:\hadoop\temp。

当我尝试格式化 Namenode 时，我收到此错误：

C:\hadoop\bin>hdfs namenode -format
