Programatic way to recursively chmod a directory
Hi,
Is there a *programatic* solution to do it recursively?
I'm using Hadoop 2.3.0.
I tried the followings:
1. I tried FileSystem.mkdirs( path, permission), it created the directory but the permission is not set correctly.
2. I tried FileSystem.setPermisison(path, permission), it changes only the current directory not recursively.
3. I tried to use FileUtil.chmod() with no luck,
4. new FsShell(conf).run(new String[]{"-chmod" , "-R", "777", "/tmp/mislam"}); it worked but looks like it is not a good solution to execute a shell.
Questions :
1. Is there a solution for this?
2. If not, is there any JIRA for this? I didn't find one.
3. What next?
Regards,
Mohammad

Hi Naga,
Thanks a lot for your answer.
I think it will definitely answer the part of my question.
For example, do you know if mkdirs works with permission?

Mohammad

Hi Mohammad,
If the user you are trying with has rights on the folder then you can try umask of 000 (like 777 - 000 =777 effective rights )
or you can check what is effective umask setting which you want to have, so that files created by this user by default has the desired rights.

Hi Mohammad,
If the user you are trying with has rights on the folder then you can try umask of 000 (like 777 - 000 =777 effective rights )
or you can check what is effective umask setting which you want to have, so that files created by this user by default has the desired rights.
