Question

我正在Windows Azure上设置Hadoop（v1.1.1）群集。我试图使用：

启动namenode进程

service hadoop-namenode start

但是，我一直收到以下错误，该错误与VM重新启动时的擦除有关。我将此目录移出，因此每次都不会删除它但仍然会发生。我们将非常感激地提供任何帮助。

Answer 1

将您指定为hdfs-site.xml文件中“dfs.name.dir”属性值的目录的权限更改为755，并将此目录的用户更改为当前用户.BTW，您是否能够成功制作格式？

由于InconsistentFSSStateException，Hadoop Namenode启动失败
