我更改了一些配置，需要重新启动nodemanager。我收到以下错误消息：
Error starting NodeManager

谢谢

是的，有一个解决办法。您可以进入yarn配置并更改java使用的tmp目录。在Yarn配置中，将'-djava.io.tmpdir=/path/to/other/temp/dir'附加到以下属性：1。ApplicationMasterJava选择base 2。jobhistory server 3的java配置选项。nodemanager 4的java配置选项。resourcemanager的java配置选项
对于作业：cloudera manager-->yarn-->搜索：gateway client environment advanced configuration snippet（safety valve）for hadoop-env.sh并添加以下内容：hadoop\u client\u opts=“-djava.io.tmpdir=/path/to/other/temp/dir”
现在重新部署yarn客户端配置。

也许，将leveldbjniwin64-1.8和leveldbjni-1.8下载到java.library.path中就可以了
你可以运行代码
System.out.println(System.getProperty("java.library.path"));获取java.library.path。
