在多节点集群中运行Hadoop无法正常工作

我安装了HDFS并在3台计算机上工作，然后我尝试向现有集群中添加5台PC，但之后尝试在主节点上启动hadoop得到下面提到的这个错误。在多节点集群中运行Hadoop无法正常工作

它清楚地说'FileNotFoundException'和'权限被拒绝'并告诉你路径。你不能为自己解决吗？ –

我会像

sudo touch /usr/local/hadoop/bin/logs/hadoop-hduser-namenode-dellnode1.pictlibrary.log

手动创建日志文件。如果你的路径是

/usr/local/hadoop/bin/../logs/hadoop-hduser-namenode-dellnode1.pictlibrary.log

更好的修复，因为我在写第一行。

然后更改文件的权限：

sudo chmod 750 /usr/local/hadoop/bin/logs/hadoop-hduser-namenode-dellnode1.pictlibrary.log

，然后再试一次。它应该这次工作;-)
