yarn DistributedCache用的有问题

```
private void setupResource(Path resourcePath, LocalResource localResource) throws IOException {
FileStatus fileStatus;
fileStatus = FileSystem.get(conf).getFileStatus(resourcePath);

localResource.setResource(URL.fromPath(resourcePath));
localResource.setSize(fileStatus.getLen());
localResource.setTimestamp(fileStatus.getModificationTime());
localResource.setType(LocalResourceType.FILE);
localResource.setVisibility(LocalResourceVisibility.PUBLIC);
}
```
LocalResourceVisibility.PUBLIC应该是LocalResourceVisibility.PRIVATE
上传到/user/xxx/.xdl除非每一层路径都是755

Locate the setupResource method shown in the issue and inspect how LocalResourceVisibility is assigned. Verify the behavior for resources uploaded under /user/xxx/.xdl, where the issue says PUBLIC requires every parent path to be 755. Done means the resource uses private visibility and the relevant behavior is covered by the project's existing checks.
