hadoop - 启动时关闭 NodeManager

Question

我在笔记本电脑上运行了 hadoop。当 hadoop 启动时，我执行命令 全部启动.cmd .然后它从 4 个守护进程开始。 cmd 显示 4 个进程中的 3 个

SHUTDOWN_MSG:在 DESKTOP-T7R9JV1/192.168.1.100 关闭 NameNode

我如何避免这种情况

Answer 1

Illegal character in opaque part at index 2

索引 2 是反斜杠，它不是有效的 URI 字符

在您的配置文件中，您需要使用正斜杠和文件 URI 协议(protocol)

例如，改变

 C:\BigData\hadoop-2.9.1\data\namenode

到

file:/C:/BigData/hadoop-2.9.1/data/namenode
