> When creating "history/done_intermediate", we seem to assume that the parent 
> directory of the folder exists and has the correct permissions. But when I 
> run it, it doesn't work. When the umask is too strict, the permission of the 
> parent directory will be wrong. Even under the default umask, the permission 
> of the parent directory cannot be guaranteed to be 777. This is because the 
> "history/done_intermediate" directory needs to be accessed by mapred, and the 
> user when the directory was created The group information is user1 and 
> supergroup, so mapred will access it as other user. It can be seen that at 
> the time of creation, only the permission setting of the last-level directory 
> is concerned (setPermission will only take effect for the last-level path), 
> and no permission is set for the parent path. In this patch, I have given 
> permissions to its parent path through the stack
