Subject Re: Programatic way to recursively chmod a directory
Date Tue, 16 Sep 2014 22:29:41 GMT
I did not try this.

What is the error or return code when you use FileUtil
https://hadoop.apache.org/docs/stable/api/org/apache/hadoop/fs/FileUtil.html#chmod(java.lang.String,
java.lang.String, boolean)

chmod

public static int *chmod*
<https://hadoop.apache.org/docs/stable/api/src-html/org/apache/hadoop/fs/FileUtil.html#line.865>(String
<http://download.oracle.com/javase/6/docs/api/java/lang/String.html?is-external=true>
filename,
                        String
<http://download.oracle.com/javase/6/docs/api/java/lang/String.html?is-external=true>
perm,
                        boolean recursive)
                 throws IOException

Change the permissions on a file / directory, recursively, if needed.

*Parameters:*filename - name of the file whose permissions are to changeperm -
permission stringrecursive - true, if permissions should be changed
